Why Does Bono Always Wear His Signature Shades?

Ask our optometrist in Brookfield how Do Sunglasses Help People With Glaucoma?

Ever wonder why rock superstar Bono wears sunglasses, even when indoors? It’s not due to his “look”, but rather is related to managing his glaucoma.

Ever wonder why Bono always wears shades, even when indoors? U2’s frontman doesn’t wear sunglasses simply as part of his image. Bono has had glaucoma, a build-up of pressure in the eyeball, which can damage the optic nerve and potentially lead to blindness if untreated—for over two decades now.

The real reason he wears his trademark shades is due to this progressive, sight-robbing eye disease, to protect his sensitive eyes from light and glare.

How Do Sunglasses Help People With Glaucoma?

People with glaucoma experience sensitivity to light (or photophobia) and glare, among other symptoms. When the sun is strong, those with this condition will be more affected by glare emanating from a variety of surfaces, like water, snow, sand or pavement, than the average person. Furthermore, certain glaucoma medications constrict the pupils, which can further contribute to acute sensitivity to glare and light, as well as redness and irritation.

That’s why people with glaucoma — and lots of people without glaucoma — feel best wearing sunglasses when outdoors on a sunny day, in a bright indoor space, or while driving in the early evening.

Here’s How You Can Protect Your Eyes

By wearing sunglasses that offer 100% UV protection, you can reduce your risk of developing sight robbing diseases, like cataracts and macular degeneration, and reduce glaucoma symptoms. Polarized lenses, in particular, can help with glare. With yearly comprehensive eye exams, early diagnosis and consistent treatment, you can prevent vision deterioration from glaucoma or similar sight-threatening eye diseases.

Can glaucoma be cured?

While there is currently no cure for glaucoma, there are many effective treatment options available. Treatments that can help stop or slow the progression of glaucoma include eye drops, oral medications, as well as laser and surgical procedures.

How can glaucoma vision loss be prevented?

The best way to avoid glaucoma-related eyesight deterioration is to undergo regular eye exams, as glaucoma can be detected and treated even in its early stages, which can prevent significant vision loss or blindness. That’s why routine eye exams that include glaucoma testing are so important.

Parkinson's Awareness Month and Your Vision

April is Parkinson’s Awareness Month in the USA and Canada, a time when those living with the disorder, their family members, friends, and community come together to raise awareness and share helpful information. People with Parkinson’s Disease (PD) and their loved ones are encouraged to share their stories, struggles, and successes in order to educate and support others.

The Parkinson’s Foundation has announced this year’s theme: #KeyToPD and Parkinson Canada advocates the same involvement. What is the key to living a high quality of life while living with Parkinson’s? Patients, doctors, caregivers, and families are encouraged to use this hashtag on social media to give of their knowledge and experience.

In order to successfully manage the disorder, it’s essential to understand the disease, symptoms, and treatments. After all, knowledge is power.

What is Parkinson’s Disease?

Parkinson’s Disease is a neurological disorder that affects the brain’s ability to control physical movement. It typically affects middle aged people and the elderly. Parkinson’s causes a decrease in the brain’s natural levels of dopamine, which normally aids nerve cells in passing messages within the brain. According to The Parkinson’s Foundation and Statistics Canada, the disorder affects an estimated 1 million people in the United States, 55 000 Canadians, and 10 million globally.

What Causes Parkinson’s Disease?

Although much research has been done on the subject, the exact cause of the disease isn’t really known. What doctors and scientists do know is that certain nerve cells located in the brain somehow break down. This damage interferes with both motor and non-motor functions.

How Does Parkinson’s Affect Vision?

Parkinson’s can have a significant impact on vision and ocular health. Patients with PD often find themselves unable to control blinking. Blinking is good for the eyes as it moisturizes the surface and clears it from foreign substances. Less blinking can cause Dry Eye Syndrome, resulting in itchy, red, or gritty-feeling eyes. Other people blink too much or can’t keep their eyes open. 

In more serious cases, Parkinson’s affects the nerves that help us see. Someone with PD may experience blurry vision, double vision, difficulty seeing color and contrast, problems with focus, and other visual symptoms. 

In addition to the inherent impact of the disease, some of the medications used to treat Parkinson’s symptoms have known side effects including dry eyes, blurred eyesight and even hallucinations in advanced PD.

Common Visual Symptoms of Parkinson’s

Although the most recognized physical symptom is uncontrollable tremors, patients can experience other symptoms that affect their vision. These typically include:

  • Apraxia (inability to open the eyelids) 
  • Blurry or double vision
  • Difficulty with balance
  • Dry eyes
  • Eye twitching
  • Focusing problems

Parkinson’s Patients and Eye Exams

Eye exams can be particularly challenging for a PD patient, so choosing the right doctor is essential. Make sure your eye doctor regularly treats patients with PD. They’ll understand your or your loved ones’ unique needs and will take the time needed.

Common Non-Visual Symptoms of Parkinson’s

PD affects other areas of the body that may or may not – depending on each patient – be related to their eye health and visual needs. 

Some of the most common non-visual symptoms are:

  • Depression
  • Excessive saliva
  • Loss of smell
  • Moodiness
  • Muscle cramps
  • Sleep disturbance
  • Slow movement (bradykinesia)
  • Stiff limbs
  • Tremors

Coping With Vision Problems From Parkinson’s

Despite the struggles caused by this degenerative disease, there is hope. Talk to your eye doctor. He or she may recommend medicated ointments or drops, injections, therapeutic lenses, visual aids, vision therapy, or a combination thereof. Additionally, a Neuro-Optometric Rehabilitation doctor can provide comprehensive eye care specifically designed for neurological disorders like PD.

Treatment for Parkinson’s Disease

There is currently no cure for the disease itself, but there are options to treat the symptoms of PD. A combination of medications, physical and/or occupational therapy, support groups, and of course, top-quality vision care can give a PD patient relief for some of their symptoms and tools to help cope with the condition.

Research and clinical trials are continuing as doctors and others in the medical community work towards the goal of finding a cure for PD.

No two patients are alike, and each can experience PD differently from the other, so finding what works for you or your loved one is key. During this Parkinson’s Awareness Month, share your #KeyToPD and give your loved ones hope for a healthy and high quality of life.

Women's Health and Your Vision

March 8th is International Women’s Day, a day when women are honored and their accomplishments celebrated worldwide. From medicine to law, entrepreneurship to corporate leadership, education to the military, women are achieving great strides in areas of business like never before.

In addition to professional achievements, International Women’s Day is a time for women to focus inwards on their personal goals, relationships, and health. From the adolescent years to pregnancy, childbirth, and menopause, women’s bodies go through some major changes that can affect many areas of their health, especially their vision.

Age Is Just a Number, But Not For Your Vision

They say that ‘age is just a number’, but when it comes to women’s health, it’s essential to pay close attention to any signs of changing vision as we get older.

Women over 40 have a higher risk of developing eye disease, impaired vision, and blindness than men. They are more likely to develop eye conditions such as Cataracts, Diabetic Retinopathy, and Dry Eye Syndrome. In fact, 61% of Glaucoma patients and 65% of Age-Related Macular Degeneration patients are female, so it’s crucial that women know the risk factors and signs of developing these conditions.

Put Your Needs First

Women are typically the family caretakers, running a spouse, children, or elderly parents to the doctor, putting their own healthcare needs last. It’s time to put your eye care needs first. Don’t ignore symptoms or push them off for another day. Take care of yourself, and you’ll be able to continue being there for others.

Signs and Risk Factors of Vision Problems

Knowing what to look out for is a crucial step in keeping your eyes healthy and enjoying great vision.

Genetics often play a key role in many health issues. Just like people inherit eye color and shape, hair color and texture, and facial features from parents, vision difficulties or diseases can also be hereditary. If something runs in the family, you may be more susceptible to developing it and passing it on to your children, as well.

Pregnancy can temporarily affect a woman’s vision. This is due to the hormonal changes in the body, which typically stabilize after breastfeeding has stopped. A pregnant woman with diabetes must be closely monitored, since diabetic retinopathy (swelling or leaking of blood vessels in the retina) can progress more quickly during the pregnancy.

Climate and environment are also important factors when it comes to eye health. Extremely cold or hot climates can cause dry eye symptoms. A healthy amount of sun exposure is good for the skin, but an excessive amount can harm your eyes and even lead to vision loss. Smoking dehydrates the skin and can lead to eye bags and dark circles, not to mention a whole slew of serious eye diseases like cataracts, macular degeneration, glaucoma, and diabetic eye disease. 

Symptoms of Declining Vision and Eye Conditions

Some of the most common signs of declining vision or eye disease include:

  • Blind spots
  • Blurry or distorted vision
  • Burning sensation
  • Gritty feeling
  • Itchy eyes
  • Redness
  • Shadows or dark spots on an image
  • Stinging
  • Swelling or soreness in the eye
  • Watery eyes

If you or a loved one experiences any of these symptoms, or if you feel like something just isn’t right with your eyes, speak with your eye doctor right away. Mention any other conditions or medications you may be taking, including birth control pills (a known contributor to Dry Eye Syndrome), and even natural supplements or vitamins. Other factors such as an irregular menstrual cycle, fertility treatments, or cosmetic procedures may impact your vision in ways you may be unaware of, so disclosing this to your doctor is important.

What Can You Do to Improve Your Eye Health?

There are some preventative measures that women can take to ensure their eye health and overall vision are at their best.

  1. Keep that body hydrated! Mothers always say it, doctors remind us too, and they’re right. Drinking 8 glasses of water daily is great for your skin and can prevent dry eye symptoms from forming.
  2. Quit smoking. Not only is it bad for your lungs, but it can cause eye problems, like dryness, itchiness, and swelling, as well as more serious eye diseases associated with vision loss.
  3. Love the outdoors? Wear UV-blocking sunglasses when you’re at the beach or even hanging out in your backyard, to protect against harmful sun rays. Polarized lenses are a great way to shield your eyes from strong glare.
  4. Eat healthy. A balanced diet including a variety of vitamin-rich fruits and vegetables may help protect you from several eye conditions including dry eyes, macular degeneration, and even diabetic retinopathy.
  5. Try to get more shut-eye. A healthy amount of sleep ensures your eyes are rested and clear the next day.

On this International Women’s Day, let’s work together to keep the women in our lives healthy for many years to come.

What's in Your Household Cleaning Supplies?

Most of us have the basics: bleach, oven cleaner, air freshener, furniture polish, and window spray. Did you know that chemicals found in these kinds of cleaning products can be toxic and harmful to your health? In small amounts, they generally don’t cause much damage. But when used on a regular basis or in a poorly ventilated area, the level of toxicity rises.

If you’ve ever gotten a headache or developed watery eyes after scrubbing down your kitchen counters, you may have a sensitivity to the chemicals in your household products.

That Burns

Volatile Organic Compounds

Volatile Organic Compounds, or VOCs, are gases that are released into the atmosphere, usually from burning fuel sources like wood or gasoline. They can also be found in many household products such as degreasers, aerosol sprays, and disinfectants. These gases are released not only during use, but also when kept in storage or transported between locations.

VOCs are generally less harmful when released outdoors, as the gases are absorbed into the atmosphere. However, in an indoor environment, the gases have 10 times the concentration!

People may come into contact with these compounds by breathing them in or through direct contact with their skin, which can lead to any of the following symptoms:

  • Headaches
  • Dizziness
  • Respiratory problems
  • Nausea
  • Impaired coordination (ie. difficulty walking straight, buttoning a shirt, or holding a pen)
  • Eye problems (ie. itching, burning, redness, or soreness in the eyes)

Other Chemical Irritants

Chemicals like sodium hydroxide can be found in oven and drain cleaners. Air fresheners and leather cleaners may contain formaldehyde, which in high amounts, has been linked to certain types of cancer. Even laundry detergents and stain removers can contain irritants.

If you’ve been exposed to these types of chemicals, you may experience trouble breathing, irritation in the eyes, nose or throat, or develop a skin rash. So, use extra caution when handling these kinds of cleaning supplies.

If your job exposes you to higher levels of chemicals from cleaning products, such as janitorial staff or sanitation workers, artificial tears and protective eyewear can help. Use them daily to give you relief from chemical agents that irritate the eyes. Ask your optometrist about which types are best for you.

Immediate Eye Care

Should your eyes come into contact with chemical substances or VOCs, immediately irrigate your eyes with plenty of cold water. Tilt your head so that the exposed eye is down, to avoid flushing the chemical into the good eye, and avoid rubbing your eyes. Rinse your eyes for 15 minutes – this will flush acidic or alkaline chemicals out of the affected areas. This should be your first line of defense, even before calling a doctor. 

If you have saline solution or contact lens solution readily on hand (non-peroxide only), administer several drops of solution to the affected eyes. Contact your eye doctor or, if need be, visit an emergency room. Chemical burns can cause serious damage to the cornea, so schedule a checkup with your eye doctor as soon as possible.

5 Ways to Lower Your Risk of Chemical Exposure

Despite the potential harm to your health, there are some things you can do to minimize over exposure to these dangerous chemicals.

1. Wash Your Hands

Our mothers always said it, and with good reason. The #1 way to lower your risk of health issues from chemicals is to wash your hands after handling cleaning products. Use warm water and soap and be sure to wash the hands thoroughly, even if you used gloves. Consider washing to your upper arms in case of a splash or splatter, such as from paint or aerosol sprays. 

2. Don’t Rub Your Eyes

Avoid touching or rubbing your eyes until your hands have been completely washed and are clear of any lingering chemical substances. Even a little foreign substance in the eye can be incredibly painful. If you’ve ever had an eyelash stuck in your eye, you know what we mean. So just imagine how severe the pain could be if you accidentally touched your eye after contact with bleach or glass cleaner.

3. Go Outside

Get some fresh air. If you feel dizzy or nauseous, if your eyes burn or you have trouble breathing after using cleaning supplies, go outside. A short walk in the fresh air can quickly open the nasal passages and clear your eyes from strong chemical vapors.

4. Open Some Windows

Make sure there is plenty of ventilation when cleaning or using any chemicals like paint. Open windows or turn some fans on to circulate the air more effectively.

5. Read Labels

Read labels and warnings so you know what’s in the cleaners you’re buying and how to use them safely. Consider trying out some natural cleaning supplies that don’t contain VOCs.

About “Green” Cleaning Products

In recent years, so-called “green” products have made their way onto store shelves, but just how green are they, and are they safer than standard ones?

While baking soda and vinegar have long been touted and praised for their cleaning abilities, there is a seeming plethora of new natural disinfectants and general cleaners on the market.

Buzzwords to Look out For

There are some buzzwords you can look out for, which are clues that certain products may not be as natural or as safe as you think. Consumer product manufacturers aren’t required by law to disclose the ingredients in artificial fragrances, so labels may simply list “fragrance” on their ingredient list. Items labeled “natural” are also vague; they don’t have to be specified, and not all natural items are necessarily safe. However, if something is listed as “flammable”, that’s a pretty sure sign of a chemical ingredient.

Chemicals & You

Simply being aware of your body’s reaction to the everyday cleaning supplies in your home is the first step. Use these items safely and with caution. For any severe eye pain – especially if you notice any vision changes – talk to your eye doctor right away.

8 Tips to Relieve Winter Dry Eyes

Whether you live in a climate with cold winter weather or you are planning a ski trip up north, winter can be a challenge if you suffer from dry eyes. Dry, cool air, cold winds and even drier indoor heating can cause eye irritation, burning, itchiness and redness, and sometimes even excessively watery eyes as more tears are produced to compensate for the dryness. Many people have a chronic feeling that they have something in their eye and some even experience blurred vision. These symptoms can be debilitating!

Dry eyes is one of the most common complaints eye doctors get from patients during the winter season, especially in the cooler climates. That’s why we’d like to share some tips on how to relieve dry eye discomfort, and how to know when your condition is serious enough to come in for an evaluation.

Tips to Relieve Winter Dry Eyes:

  1. Keep eyes moist using artificial tears or eye drops. You can apply these a few times each day when the eyes are feeling dry or irritated. If over-the-counter drops don’t help or if you have chronic dry eyes, speak to your eye doctor about finding the best drops for you. Since not all artificial tears are the same, knowing the cause of your dry eye will help your eye doctor determine which brand is best suited for your eyes.
  2. Use a humidifier to counteract the drying effects of indoor heaters or generally dry air.
  3. Point car vents or indoor heaters away from your face when the heat is on. Try to keep your distance from direct sources of heating, especially if they blow out the heat.
  4. Drink a lot! Hydrating your body will also hydrate your eyes.
  5. Protect your eyes outdoors with sunglasses or goggles – the bigger the better! Larger, even wrap-around glasses as well as a hat with a wide brim will keep the wind and other elements out of your eyes. If you wear goggles for winter sports, make sure they fit well and cover a large surface area.
  6. Soothe dry eyes using a warm compress and never rub them! Rubbing your eyes will increase irritation and may lead to infection if the hands are not clean.
  7. Give your eyes a digital break. People blink less during screen time which is why extensive computer use can lead to dry eyes. Follow the 20/20/20 rule by taking a break every 20 minutes to look 20 feet away for 20 seconds and make sure you blink!
  8. For contact lens wearers: If you wear contact lenses, dry eyes can be particularly debilitating as the contact lenses can cause even further dryness and irritation. Contact lens rewetting drops can help your eyes feel better and may also allow you to see more clearly. Not all eyedrops are appropriate for use with contact lenses, so ask your optometrist which eyedrop is compatible with your contacts and cleaning solution. If rewetting drops don’t help, consider opting for glasses when your dry eyes are bad, and speak to your optometrist about which brands of contact lenses are better for dry eyes. Many people find dry eye improvement when they switch to daily single use contact lenses.

Chronic Dry Eyes or Dry Eye Syndrome

Dry eye syndrome is a chronic condition in which the eyes do not produce enough tear film, or do not produce the quality of tear film needed to properly keep the eyes moist. While winter weather can make this condition worse, it is often present all year round. If you find that the tips above do not alleviate your discomfort or symptoms, it may be time to see a optometrist to see if your condition requires more effective medical treatment.

Diabetes and Your Eyes

Diabetes is becoming much more prevalent around the globe. According to the International Diabetes Federation, approximately 425 million adults were living with diabetes in the year 2017 and 352 million more people were at risk of developing type 2 diabetes. By 2045 the number of people diagnosed is expected to rise to 629 million.

Diabetes is a leading cause of blindness as well as heart attacks, stroke, kidney failure, neuropathy (nerve damage) and lower limb amputation. In fact, in 2017, diabetes was implicated in 4 million deaths worldwide. Nevertheless preventing these complications from diabetes is possible with proper treatment, medication and regular medical screenings as well as improving your diet, physical activity and adopting a healthy lifestyle.

What is Diabetes?

Diabetes is a chronic disease in which the hormone insulin is either underproduced or ineffective in its ability to regulate blood sugar. Uncontrolled diabetes leads to hyperglycemia, or high blood sugar, which damages many systems in the body such as the blood vessels and the nervous system.

How Does Diabetes Affect The Eyes?

Diabetic eye disease is a group of conditions which are caused, or worsened, by diabetes; including: diabetic retinopathy, diabetic macular edema, glaucoma and cataracts. Diabetes increases the risk of cataracts by four times, and can increase dryness and reduce cornea sensation.

In diabetic retinopathy, over time, the tiny blood vessels within the eyes become damaged, causing leakage, poor oxygen circulation, then scarring of the sensitive tissue within the retina, which can result in further cell damage and scarring.

The longer you have diabetes, and the longer your blood sugar levels remain uncontrolled, the higher the chances of developing diabetic eye disease. Unlike many other vision-threatening conditions which are more prevalent in older individuals, diabetic eye disease is one of the main causes of vision loss in the younger, working-age population. Unfortunately, these eye conditions can lead to blindness if not caught early and treated. In fact, 2.6% of blindness worldwide is due to diabetes.

Diabetic Retinopathy

As mentioned above, diabetes can result in cumulative damage to the blood vessels in the retina, the light-sensitive tissue located at the back of the eye. This is called diabetic retinopathy.

The retina is responsible for converting the light it receives into visual signals to the optic nerve in the brain. High blood sugar levels can cause the blood vessels in the retina to leak or hemorrhage, causing bleeding and distorting vision. In advanced stages, new blood vessels may begin to grow on the retinal surface causing scarring and further damaging cells in the retina. Diabetic retinopathy can eventually lead to blindness.

Signs and Symptoms of Diabetic Retinopathy

The early stages of diabetic retinopathy often have no symptoms, which is why it’s vitally important to have frequent diabetic eye exams. As it progresses you may start to notice the following symptoms:

  • Blurred or fluctuating vision or vision loss
  • Floaters (dark spots or strings that appear to float in your visual field)
  • Blind spots
  • Color vision loss

There is no pain associated with diabetic retinopathy to signal any issues. If not controlled, as retinopathy continues it can cause retinal detachment and macular edema, two other serious conditions that threaten vision. Again, there are often NO signs or symptoms until more advanced stages.

A person with diabetes can do their part to control their blood sugar level. Following the physician’s medication plan, as well as diet and exercise recommendations can help slow the progression of diabetic retinopathy.

Retinal Detachment

Scar tissues caused by the breaking and forming of blood vessels in advanced retinopathy can lead to a retinal detachment in which the retina pulls away from the underlying tissue. This condition is a medical emergency and must be treated immediately as it can lead to permanent vision loss. Signs of a retinal detachment include a sudden onset of floaters or flashes in the vision.

Diabetic Macular Edema (DME)

Diabetic macular edema occurs when the macula, a part of the retina responsible for clear central vision, becomes full of fluid (edema). It is a complication of diabetic retinopathy that occurs in about half of patients, and causes vision loss.

Treatment for Diabetic Retinopathy and Diabetic Macular Edema

While vision loss from diabetic retinopathy and DME often can’t be restored, with early detection there are some preventative treatments available. Proliferative diabetic retinopathy (when the blood vessels begin to grow abnormally) can be treated by laser surgery, injections or a procedure called vitrectomy in which the vitreous gel in the center of the eye is removed and replaced. This will treat bleeding caused by ruptured blood vessels. DME can be treated with injection therapy, laser surgery or corticosteroids.

Prevent Vision Loss from Diabetes

The best way to prevent vision loss from diabetic eye disease is early detection and treatment. Since there may be no symptoms in the early stages, regular diabetic eye exams are critical for early diagnosis. In fact diabetics are now sometimes monitored by their health insurance to see if they are getting regular eye exams and premium rates can be affected by how regularly the patients get their eyes checked. Keeping diabetes under control through exercise, diet, medication and regular screenings will help to reduce the chances of vision loss and blindness from diabetes.

7 Eye Symptoms You Shouldn't Ignore

While we all know that regular eye exams can help detect warning signs of disease and prevent vision loss, many people fail to seek medical attention when there is an acute problem with the eye. In fact, only about half of Americans that are at risk for serious vision loss have been examined by an eye doctor within the last year, according to a report by the Centers for Disease Control and Prevention. 

While it’s true that some eye symptoms resolve on their own, it’s better not to take the chance when your eyesight is at risk. Here are seven eye symptoms that should be checked out by an eye doctor immediately, as they could indicate a serious underlying condition that could threaten your vision. Remember, even if you think the issue is minor, getting proper medical attention could be vital to saving your vision. 

  1. Frequent Floaters

    Floaters are shadows or spots that appear to float through your field of vision, particularly when you are looking at a solid colored or bright background such as the blue sky or a white wall. They can appear in a variety of shapes such as a shower of dots or mosquito shaped for example. It is common to see floaters on occasion, however if you experience a sudden increase, especially in combination with pain, flashes or loss of peripheral vision, you should see a doctor immediately. Flashes of light may appear as a quick spark or jagged streaks of light or arcs among other shapes. This could be a sign of a very serious problem such as detached or torn retina, a hemorrhage or bleeding inside the eye, an inflammation of the vitreous or retina caused by an infection or injury or an eye tumor. In the case of a retinal detachment, the different pattern of floaters or flashes depend on how the retina tears, so if you suddenly notice a distinct pattern of floaters or light in your vision, don’t delay: seek medical attention within 24 hours. 

  2. Persistent Redness or Irritation

    While minor redness can simply be a result of allergies, exhaustion or extended contact lens wear, there are some more serious causes of eye redness, especially if it persists or is accompanied by pain, swelling, discharge, vision disturbance or severe itchiness. Along with conjunctivitis (or pink eye) which can be a very contagious eye infection, redness can indicate a corneal scratch, uveitis or glaucoma. 

  3. Excessive Watery Eyes 

    Whether you have a foreign object in your eye or are experiencing dryness due to allergies or environmental factors, eye watering is a natural response to keep your eyes healthy, comfortable and safe. When it is constant and disruptive, however, this is no longer normal. Excessive eye watering could indicate a chronic condition such as dry eye syndrome, tear duct problems or problems with the cornea such as a scratch or an ulcer.

  4. Foreign Body in the Eye

    If you experience a foreign object in your eye, the first thing to do it try to flush it out. Never rub the eye as it could cause even greater damage. If your efforts to flush the object out are not successful it is time to see a doctor. Additionally, if you are experiencing vision disturbances, pain or redness while the object is there or after you think you have removed it, see an eye doctor immediately. 

  5. Ptosis (Droopy Eyelid) 

    Ptosis or drooping eyelids is seen in one or both eyelids and can be caused by benign conditions such as allergies or merely part of the aging process. Nevertheless, it can also be a sign of a serious condition such as nerve damage, a stroke, brain tumor or a condition called myasthenia gravis, which is a neurological condition that affects the muscles of the eye. It is also sometimes a result of eye surgery or injury. Often ptosis will resolve gradually on its own, however it is something that should be checked out, especially if it occurs suddenly, to ensure there is no serious underlying cause. 

  6. Bleeding Eyes 

    A subconjunctival hemorrhage in the eye is when a blood vessel right under the surface of the eye breaks. You will see that the white part or sclera of the eye has turned red. Usually, this common occurrence is nothing to be concerned about as this can happen from something as simple as straining, a sneeze or cough. In this case there is nothing to do and it will resolve on its own. If however, the redness comes after an injury to your eye or head it could indicate that there is bleeding in the brain and should be examined immediately.

  7. Moderate to Severe Eye Pain 

    There are several causes of eye pain, the most serious of which is acute angle closure glaucoma or uveitis. Other causes of pain can include corneal abrasions and ulcers, scleritis, orbital cellulitis and sinusitis. 

When it comes to problems with the eye, it’s always best to err on the side of caution and get them checked out. Doing otherwise, could cost you your eyesight. Your eye doctor can help.

Inside a Life With Color Vision Deficiency

What’s it like to be color blind? Contrary to what the name implies, color blindness usually does not actually mean that you don’t see any color, but rather that you have difficulty perceiving or distinguishing between certain colors. This is why many prefer the term color vision deficiency or CVD to describe the condition. CVD affects men more than women, appearing in approximately 8% of men (1 in 12) and .5% of women (1 in 200) worldwide. 

Having color vision deficiency means that you perceive color in a more limited way than those with normal color vision. This ranges from mild, in which you may not even be aware that you are experiencing color differently, to severe, which is perhaps the more appropriate from to be called “color blind” and involves the inability to see certain colors. 

CVD can be inherited; it is caused by abnormalities in the genes that produce photopigments located in the cone cells in your eyes. The eyes contain different cone cells that fire in response to a specific color, blue, green or red and together allow you to see the depth and range of colors that the normal eye can see. The type of color blindness and therefore the type of color vision that is impaired, is based on which photopigments are abnormal. The most common form of CVD is red-green, followed by blue-yellow. Total color blindness or the complete inability to perceive color is quite rare. About 7% of males have congenital color blindness that they inherit from the mother’s X-chromosome. 

Color blindness can also be the result of eye damage, specifically to the optic nerve, or to the area in the brain that processes color. Sometimes an eye disease, such as cataracts, can also impact one’s ability to perceive color. Systemic diseases such as diabetes or multiple sclerosis can also cause acquired CVD. 

Living with CVD

Red-green color blindness does not mean only that you can’t tell the difference between red and green, but rather that any color that has some red or green (such as purple, orange, brown, pink, some shades of gray, etc) in it is affected. 

You many not realize all of the ways you use even subtle distinctions in color in your daily life. Here are some examples of ways that CVD can impact your life and make seemingly everyday tasks challenging:

  • You may not be able to cook meat to the desired temperature based on color. 
  • Most of the colors in a box of crayons will be indistinguishable.
  • You may not be able to distinguish between red and green LED displays on electronic devices that indicate power on and off. 
  • You may not be able to tell between a ripe and unripe fruit or vegetable such as bananas (green vs. yellow) or tomatoes (red vs green). 
  • Chocolate sauce, barbecue sauce and ketchup may all look the same. 
  • Bright green vegetables can look unappealing as they appear greenish, brown or grey. 
  • You may not be able to distinguish color coded pie charts or graphs (which can cause difficulty in school or work). 
  • Selecting an outfit that matches can be difficult. 

Knowing that one is color blind is important for some occupations that require good color discrimination such as the police officers, railway workers, pilots, electricians etc.  These are just a few of the ways that CVD can impact one’s daily life. So is there a cure? Not yet. 

While there is no cure for CVD, there is research being done into gene therapies and in the meantime there are corrective devices available including color vision glasses (such as the Enchroma brand) and color filtering contacts that for some can help to enhance color for some people. If you think you might have CVD, your optometrist can perform some tests to diagnose it or rule it out. If you have CVD, you can speak to your eye doctor about options that might be able to help you experience your world in full color. 

Pink, Stinging Eyes?

Conjunctivitis, also called pink eye, is one of the most frequently seen eye diseases, especially in kids. It can be caused by viruses, bacteria or even allergies to pollen, chlorine in swimming pools, and ingredients in cosmetics, or other irritants, which touch the eyes. Some forms of conjunctivitis might be quite transmittable and quickly spread in school and at the office.

Conjunctivitis is seen when the conjunctiva, or thin transparent layer of tissue covering the white part of the eye, becomes inflamed. You can identify conjunctivitis if you notice eye redness, discharge, itching or swollen eyelids and a crusty discharge surrounding the eyes early in the day. Pink eye infections can be divided into three main types: viral, allergic and bacterial conjunctivitis.

The viral type is usually a result of a similar virus to that which produces the recognizable red, watery eyes, sore throat and runny nose of the common cold. The red, itchy, watery eyes caused by viral pink eye are likely to last from a week to two and then will clear up on their own. You may however, be able to reduce some of the discomfort by using soothing drops or compresses. Viral pink eye is transmittable until it is completely cleared up, so in the meantime maintain excellent hygiene, remove eye discharge and try to avoid using communal pillowcases or towels. If your son or daughter has viral conjunctivitis, he or she will have to be kept home from school for three days to a week until symptoms disappear.

A bacterial infection such as Staphylococcus or Streptococcus is usually treated with antibiotic eye drops or cream. One should notice an improvement within just a few days of antibiotic drops, but be sure to adhere to the full prescription dosage to prevent pink eye from recurring.

Allergic pink eye is not contagious. It is usually a result of a known allergy such as hay fever or pet allergies that sets off an allergic reaction in their eyes. First of all, to treat allergic pink eye, you should eliminate the irritant. Use cool compresses and artificial tears to relieve discomfort in mild cases. When the infection is more severe, your eye doctor might prescribe a medication such as an anti-inflammatory or antihistamine. In cases of chronic allergic pink eye, topical steroid eye drops could be used.

Pink eye should always be diagnosed by a qualified eye doctor in order to identify the type and best course of treatment. Never treat yourself! Keep in mind the sooner you begin treatment, the lower chance you have of giving pink eye to loved ones or prolonging your discomfort.
