While it may seem like a harmless action, rubbing your eyes can actually cause a lot of damage. There are a number of different reasons that people rub their eyes and for the most part, it does more harm than good. While rubbing your eyes might feel really good in the short term, it’s best to find other ways to get relief from your symptoms.

Why People Rub Their Eyes

Rubbing your eyes can feel good for a number of reasons. First of all, it can be therapeutic as the pressure can be soothing and can stimulate the vagus nerve, alleviating stress. It can also lubricate your eyes by stimulating the tear ducts and can flush out or remove dirt and particles.

However, you don’t want to make eye rubbing a habit because there are a number of ways it can cause damage. Let’s take a look at some of the reasons people rub their eyes and some ways to avoid it.

Tired

If you are rubbing your eyes because you are tired, think again. Rubbing your eyes frequently can contribute to bloodshot eyes and dark circles due to the breakage of tiny blood vessels in and around your eyes. If you are already tired, this can add to an even more worn-out appearance.

Itchy

Itchy eyes can be caused by a number of reasons including allergies, inflammation or infections. In any case, rubbing them can often make things worse. For allergies, rubbing the eyes can actually make your eyes more itchy because it can spread more allergens around. Further, there is an inflammatory cascade response that is aggravated by eye rubbing, which can cause the intense fluid swelling and redness often associated with allergies.

If you have an infection, rubbing your eye can cause more irritation, and often spreads the infection to your other eye, and potentially to the people around you. In fact, that may be how you got that infection to begin with. The hands carry a good amount of germs and bacteria, and your eyes are an easy access point for these germs to enter. Touching something, even as common as a doorknob or towel, which someone else with an eye infection also touched, is a common cause of conjunctivitis and other contagious eye infections.

Something In Your Eye

If you have something in your eyes, rubbing may seem like the natural response to get it out. However, this can cause the object to scratch your eye and damage the cornea. Rubbing may occasionally push a foreign body deeper into the cornea making it more painful and difficult to remove.

Dry Eyes

Dry eyes can be temporary, resulting from environmental or physical circumstances, or chronic, due to a condition like blepharitis in which the eye produces a poor quality tear film. If you rub your eyes when they feel dry, it can exacerbate your discomfort and even sometimes cause infection if you don’t wash your hands first. When your eyes don’t have enough tears, they may not flush dirt and germs out as readily as well-lubricated eyes might.

Other Eye Conditions

Eye rubbing can be especially risky for people with existing eye conditions such as glaucoma, thin cornea and progressive myopia, as it can worsen eyesight. In glaucoma the eye rubbing can lead to an increase in eye pressure which can lead to nerve damage and eventual vision loss. In individuals with a thin cornea, eye rubbing can exacerbate the problem sometimes resulting in a condition called keratoconus which seriously distorts vision.

Alternatives to Eye Rubbing

Eye Wash

Your eyes actually have built-in mechanisms to flush out particles and irritants, but when these don’t work, eye flushing, eye drops or artificial tears might bring relief or remove foreign bodies. If you think you have a foreign body in the eye, first flush the eye with saline, eye wash or water. If you have something stuck in your eye that you can’t flush out, go immediately to an eye doctor.

Eye Drops or Cool Down

For chronic itching or allergies, speak to your eye doctor as there are remedies such as antihistamines, mast cell stabilizers or even steroid eye drops that can be prescribed to alleviate symptoms. If no prescription eye drops are available when needed, try cooling down by going to a cool area and putting cold water on a paper towel over the eyes for a few minutes. Cooling the eye area will reduce symptoms as the blood vessels constrict, while heat tends to make the itch worse.

If you have dry eyes there are a number of options available for treatment which include drops or procedures to clear out tear ducts to improve eye moisture.

Remember, no matter how good it may feel to rub your eyes, there are potential consequences, some of them serious, so next time, think twice!

It’s that time of the year again. Each February, the optometric community bands together to create awareness about age-related macular degeneration (AMD). AMD is a leading cause of vision loss for people 50 years and older; early detection plays a key role in the outcome of the disease. That’s why bringing awareness to the disease and its risk factors is so important.

Macular degeneration is a disease that damages the macula, which is a small area in the center of the retina responsible for sharp, clear central vision. The disease comes in two forms, wet AMD and dry AMD. The most common form, dry AMD, which affects around 80% of AMD patients, is when the macula gradually thins, and small clusters of protein called drusen begin to grow. Drusen result from cells in the macula that cannot rid themselves of metabolic waste called lipofuscin. The lipofuscin accumulates as drusen which causes a gradual vision decline.

Dry AMD can turn into wet AMD when abnormal new blood vessels grow through breaks in a membrane layer of the thinning macula. The fragile blood vessels leak fluid into the macula, causing rapid decrease in central vision.The wet form is less common, yet it can cause a faster and more drastic vision loss. If a person has dry AMD which turns into wet AMD, this should be treated as soon as possible, as within days this can cause permanent scarring. Fortunately, there is effective treatment for wet AMD if detected before scarring arises.

Both forms of AMD result in a loss of central vision, while peripheral vision stays intact. Symptoms can present as difficulty focusing on objects in front of you, or a blurred or dulled area in the central visual field which leads to having trouble reading, doing close work, driving or even recognizing faces. With time, the size of the blurred area can grow and eventually develop into black spots in central vision. Oftentimes patients don’t even notice symptoms until a significant amount of damage has been done. This is why regular eye exams are critical, especially if you are at risk.

While AMD alone won’t cause complete blindness, it can cause a permanent, total loss of central vision if not treated. Vision loss can lead to a condition called low vision which can have a very serious impact on daily living and require a lot of assistance both by vision devices and the help of others.

Are You at Risk?

As it is an age-related disease, age is a significant risk factor for AMD, specifically once you reach 60. However, age is not the only risk factor. While some risk factors for AMD cannot be controlled there are lifestyle factors that you can change to prevent AMD.

Other than age, risk factors include:

• Family history: If you have a family history of AMD, you are more at risk. Research has identified at least 20 genes that are associated with AMD, showing there is a genetic factor.
• Race: Caucasian descent is a higher risk factor for AMD, and in fact, Caucasians with light irises have an increased risk from age 50.
• Smoking: Smoking doubles your risk of developing AMD.
• Overweight/Obesity: Research shows that being overweight is a risk factor for AMD.
• Having heart disease, high blood pressure and high cholesterol increase your risks.
• Diet: An unhealthy diet rich in saturated fats is a significant risk factor.
• Early exposure to UV light and blue hazard light (especially with the younger generation having increased exposure to digital devices) can cause early onset AMD.

Here are some lifestyle steps you can take to reduce your risk of AMD:

• Stop smoking
• Eat a healthy diet rich in omega 3 fatty acids, (from fatty fish or flax seeds), leafy greens and colorful fruits and vegetables.
• Know your family history.
• Exercise regularly.
• Protect your eyes using UV protection and blue blocker coatings on eyeglasses.
• Get regular eye exams.

In addition to a comprehensive eye exam, your doctor may be able to test for certain risk factors. For example, there is now technology available that can test for lutein levels via technology such as QuantifEye and Macuscope, (low lutein can indicate increased risk). In addition, genetic testing is also now available through a simple cheek swab to determine an individual’s risk for developing AMD.

Treatment

There is no known cure for AMD, however there are treatments available that may slow the progression of the disease. For dry AMD, studies (AREDS and AREDS2) have concluded that a particular high-dose combination of nutritional supplements taken daily can slow the disease. The combo includes vitamins C and E, Lutein, Zeaxanthin, Zinc and Copper. For wet AMD, the goal is to reduce the growth of abnormal blood vessels and the leakage that takes place and this is done through certain medications called anti-VEGFs which are injected into the eye or with laser surgery.

Untreated macular degeneration can have devastating effects on your independence and quality of life. If you are 50 or over, speak to your eye doctor about your risk factors and what you can do to prevent AMD.

As the season to deck the halls arrives, make sure that you aren’t one of the many people who find themselves celebrating in the urgent care clinic due to an eye injury. The holidays present many opportunities for potential eye injury so it’s important to be aware and proceed with caution. Here are some common eye accidents waiting to happen and tips to avoid them so you can be prepared and enjoy your holidays to the fullest!

1. An eye-full of pine

   Many accidents occur when proper care is not taken in putting up and decorating the Christmas tree. First of all, if you are cutting down your own tree, make sure you are wearing proper eye protection both when cutting and when loading your tree onto your car. If you are buying a tree, be extra careful when untying it as branches can pop out rather fast – a definite danger to your eyes! It’s best to wear glasses or goggles during the entire process of handling the tree. And don’t forget to be careful when you are decorating! All you need is a wobbly ladder or an unsteady tree stand to cause a tumble into the sharp, prickly pine needles. Not to mention, sharp ornaments can pose a danger to the eyes as well.

2. The spray snow slip-up

   Spray snow can be a beautiful and festive addition to your tree decorations but be careful that you are always pointing it in the right direction. Make sure the spray you purchase is nontoxic and wear safety goggles when spraying to avoid an accidental spray to the eye. Be wary of those aerosol string cans as well.

3. Champagne cork projectile

   Watch out for that bubbly! When opening a champagne bottle always point it away from anyone or anything breakable just in case it shoots off. That flying cork can cause a serious bruise or an eye injury if you aren’t careful.

4. You’ll shoot an eye out!

   Just like the famous movie quote predicted, toy guns and projectiles can be a tremendous danger to the eye, causing almost 20% of eye injuries during the holiday season. Nerf guns, darts (even foam darts), slingshots, water guns and any kind of shooting device, no matter how soft the ammunition, can cause serious eye damage when shot directly into the eye. Be wary of lasers as well and make sure that any laser products comply with the national regulations. Lasers and very bright lights can cause retinal damage if pointed directly at the eye. If you do decide to purchase such a toy for a child that is old enough and mature enough to be responsible, consider buying proper eye protection to go along with the gift.

   Avoid purchasing any toys or gifts that have sharp, protruding parts and make sure that any potentially hazardous toys are played with under adult supervision. When purchasing gifts, if you are uncertain about the safety of a certain toy, check out W.A.T.C.H. (World Against Toys Causing Harm) or other organizations that give advice about specific toy safety.

5. Dangerous dress up

   Got a holiday party on the horizon? While you may be tempted to add a pair of cosmetic contact lenses to your ensemble, make sure they are fit properly and purchased by a licensed eye doctor. Improperly fit lenses or lenses made of sub par materials can cause serious complications such as a corneal abrasion or infection.

6. Sunburned eyes

   If your holiday time includes a chance to play in the snow or ice, make sure you have your sunglasses ready. UV light reflects off snow and ice increasing the risk of sunburned eyes and potential long term damage. Winter sunwear is just as important as it is during summer fun in the sun.

If you approach the holidays with the eyes on your mind, you can stay safe and avoid potential injury that could put a damper on your festivities.

It’s National Cataract Awareness Month

According to the World Health Organization, cataracts are responsible for 51% of cases of blindness worldwide – although this blindness is preventable with treatment. In fact, research shows that in industrialized countries about 50% of individuals over the age of 70 have had a cataract in at least one eye. This is partially because cataracts are a natural part of the aging process of the eye, so as people in general live longer, the incidence of cataracts continue to increase.

What are Cataracts?

Cataracts occur when the natural lens in the eye begins to cloud, causing blurred vision that progressively gets worse. In addition to age, cataracts can be caused or accelerated by a number of factors including physical trauma or injury to the eye, poor nutrition, smoking, diabetes, certain medications (such as corticosteroids), long-term exposure to radiation and certain eye conditions such as uveitis. Cataracts can also be congenital (present at birth).

The eye’s lens is responsible for the passage of light into the eye and focusing that light onto the retina. It is responsible for the eye’s ability to focus and see clearly. That’s why when the lens is not working effectively, the eye loses it’s clear focus and objects appear blurred. In addition to increasingly blurred vision, symptoms of cataracts include:

“Washed Out” Vision or Double Vision:

People and objects appear hazy, blurred or “washed out” with less definition, depth and color. Many describe this as being similar to looking out of a dirty window. This makes many activities of daily living a challenge including reading, watching television, driving or doing basic chores.

Increased Glare Sensitivity:

This can happen both from outdoor sunlight or light reflected off of shiny objects indoors. Glare sensitivity causes problems with driving, particularly at night and generally seeing our surroundings clearly and comfortably.

Dulled Colors:

Often colors won’t appear as vibrant as they once did, often having a brown undertone. Color distinction may become difficult as well.

Compromised Contrast and Depth Perception:

These eye skills are greatly affected by the damage to the lens.

Darkened Vision:

Often individuals with cataracts find that they require more light than they used to, to be able to see clearly and perform basic activities.

Cataract Treatment

Early stage cataracts may be able to be treated with glasses or lifestyle changes, such as using brighter lights, but if they are hindering the ability to function in daily life, it might mean it is time for cataract surgery.

Cataract surgery is one of the most common surgeries performed today and it involves removing the natural lens and replacing it with an artificial lens, called an implant or an intraocular lens. Typically the standard implants correct the patient’s distance vision but reading glasses are still needed. However as technology has gotten more sophisticated you can now get multifocal implants that can reduce or eliminate the need for glasses altogether. Usually the procedure is an outpatient procedure (you will go home the same day) and 95% of patients experience improved vision almost immediately.

Cataract Prevention

While doctors still don’t know exactly how much each risk factor leads to cataracts there are a few ways you can keep your eyes healthy and reduce your risks:

• Refrain from smoking and high alcohol consumption
• Exercise and eat well, including lots of fruits and vegetables that contain antioxidants
• Protect your eyes from UV radiation like from sunlight
• Control diabetes and hypertension

Most importantly, see your eye doctor regularly for a comprehensive eye exam. If you are over 40 or at risk, make sure to schedule a yearly eye exam.

You Don’t Have to Live With Dry Eyes

Have you noticed that your eyes feel chronically dry, itchy, scratchy or even sometimes watery? Many people that have these symptoms just go on with their lives until the symptoms become unbearable. What they don’t realize is that these are signs that they might be suffering from dry eye syndrome, a condition in which the eyes are not able to produce enough tears to effectively lubricate the eyes. This is a problem that won’t just go away on its own.

What causes Dry Eye?

Dry Eye Syndrome, also known as Tear Film Dysfunction is characterized by a reduction in the amount or quality of tears that are produced. Tears are essential for optimal eye health, vision and comfort. Ideally, tear film covers the eyes at all times to prevent the eyes from drying out and to ensure clear vision. If the glands that produce tears start to produce fewer tears or tears that don’t have the proper balance of water, oils, proteins and electrolytes, the tear film with become unstable, allowing dry spots to form on the surface of the eye, and cause disruptions in outer barrier of the eye’s epithelial surface. This disruption in the outer barrier allows microbes to invade the eye, leading to irritation and infection. The condition can be caused by many factors, including tear gland dysfunction, eyelid problems, medications or environmental factors.

Symptoms of Dry Eye

As mentioned above, many of the symptoms of dry eye involve varying sensations of dryness including, burning, stinging, itching, grittiness, soreness or a feeling that there is something in the eye. The eyes may also be red and sensitive to light, wind or smoke. Vision may be blurred or doubled and the eyes may fatigue easily. Another common symptom is that vision seems blurry but clears when you blink (especially common when reading or using a computer). This is because the tear film does not form a smooth coat over the eye surface or it evaporates too quickly causing a blur.

You may also notice pain, some discharge from the eye (especially upon waking in the morning) and experience discomfort when wearing contact lenses. One of the most confusing symptoms of dry eye is actually excessive tearing, which occurs because the eyes are trying to compensate for the lack of moisture – however the tears produced are low quality and don’t properly hydrate the surface of the eye.

Reducing Symptoms

The first thing to look at when you have dry eyes is whether you are taking any medications, engaging in certain behaviors or being exposed to environmental factors that may be causing the condition. Medications that may cause dry eye as a side effect include:

• Antihistamines and Decongestants
• Diuretics
• Sleeping pills
• Birth Control pills
• Antidepressants
• Acne medications
• Angiotensin-converting enzyme (ACE) inhibitors
• Opiate-based painkillers such as morphine

Important! Never stop medication without the approval of your doctor! If you are taking a medication that may be causing dry eye, don’t stop taking the medication without speaking to your healthcare provider first. Treating dry eye symptoms may be a simpler solution than stopping or switching medications.

You may be able to alter your environment to reduce symptoms of dry eye as well. Environmental factors that can exacerbate dry eye include:

• Wearing contact lenses
• Extended use of computers or other electronic devices
• Exposure to dry, windy climates or blowing air (such as an air conditioner or heater).
• Exposure to smoke
• High altitudes

Treatment for Dry Eye

If you are experiencing dry eye symptoms, make an appointment with your optometrist. The diagnosis and treatment will be based on a complete examination of your eyes, your medical history and your personal circumstances around the condition. The doctor may decide to perform a tear film test that can determine the quantity and quality of the tears and whether your tear glands and tear film are functioning properly.

The type of treatment will depend on the underlying cause of the problem. Treatment may include behavioral or environmental changes such as using a humidifier, wearing sunglasses in windy weather, reducing computer time or changing to a different type of contact lens, as well as medical treatments that may include:

• Artificial tears, eye drops or ointments to lubricate eyes
• Steroid or antibiotic drops or pills may be used for certain conditions such as blepharitis
• Reducing the drainage of tears by blocking tear ducts with silicone plugs
• Medications such as Restasis which reduce inflammation and trigger tear production
• In some situations a surgical procedure might be recommended
• Scleral lenses that hold moisture on the surface of the eyeball

The most important thing you should know about dry eyes is that you do not have to suffer. Treatments are available to increase moisture on your eye and reduce the uncomfortable and sometime debilitating symptoms. If you are suffering, schedule an appointment with your eye doctor and get the relief you deserve.
