5 Things You Didn’t Know About Your Eyes

Posted by CooperVision on Friday, August 10, 2012

A lot of patients don’t realize it, but the human eye is an amazing organ that allows us to live our lives everyday. Here are some interesting and fun facts about the eyes that you may not have known:

  • More than half of all people in the United States use some type of lens to correct their vision. Are you one of them? Make sure to ask your eye doctor about contact lenses as an option. You can take this survey to find out which of our contact lenses are right for you and get the conversation started.
  • Your eyes keep growing after birth which is why refractive changes can occur during childhood and require corrective lenses such as contact lenses. This is why it is important for everyone to get regular eye exams because everyone’s eyes change over time.
  • All types of eye drops sting less if you store them in the refrigerator.
  • When you blink, you shut your eyes for 0.3 seconds. That’s a total of 30 minutes each day. However, when people stare at computer screens for too long, they may blink less. Blinking less can lead to eye strain, fatigue and dry eye. Make sure to talk to an eye doctor about ways to make sure you can avoid computer vision.
  • The retina is about the size of a postage stamp. It has 130 million light sensitive cells.

August Is Children's Eye Health and Safety Month

Posted by CooperVision on Thursday, August 2, 2012

According to the Centers for Disease Control (CDC) only one in three children in America have ever received eye care services before age six, yet more than 12.1 million school aged children have some form of vision problem. August is a month where eye-damaging UV rays are still strong and school is just around the corner – the perfect time for Children’s Eye Health and Safety Month.

An annual comprehensive eye exam is an important part of monitoring eye and the overall health in children, so it is recommended that school-aged children and teens get eye exams annually. Undetected vision problems can affect a child’s physical ability, readiness to learn, and self esteem. For more information on the importance of vision and eye health in children, be sure to check out the National Center For Children’s Vision and Eye Health.

Here is a list of great resources that you and your child can learn from during the month of August

  • Making Every Day A Healthy Vision Day Calendar: is a great way for kids to learn fun eye related facts.
  • Simple Tips For Healthy Eyes: is a list compiled by the National Eye Institute that make maintaining healthy eyes a snap.
  • Kids Quest About Vision Impairment: is an online quest that older kids can take in order to learn more about vision impairment and how it affects children.

Eye Nutrition Tips

Posted by CooperVision on Thursday, July 12, 2012

Eye nutrition is important. Did you know that there are five essential nutrients that help promote healthy vision and may reduce the risk of eye disease? Certain studies have shown that taking an antioxidant or vitamin supplement can reduce the risk of advanced AMD progression and visual acuity loss. Since not all of these nutrients are created in the body, it is crucial to get these nutrients from diet or supplements. Here is a list of the 5 essential nutrients for healthy eyes and what patients should eat:

Lutein With Zeaxanthin

Lutein and zeaxanthin are nutrients that are naturally found together in foods such as leafy spinach, kale, eggs, and corn. These two nutrients act as antioxidants by helping protect and maintain healthy cells in the eye. The amount of lutein and zeaxanthin deposited in the macula can be measured macular pigment potical density (MPOD). Research has shown that higher levels of MPOD can increase levels of visual range and visual performance. Studies have also shown that patients with higher levels of MPOD have a greater tolerance for the intensity of glaring light and a shorter recovery time from glare.

Foods rich in lutein and zeaxanthin are: spinach, collard greens, corn, eggs, turnips, green peas, broccoli, and oranges.

Vitamin C

Vitamin C is an antioxidant that is typically found in fruits and vegetables. It helps promote healthy capillaries, cartilage, and iron absorption. It helps support the health of ocular blood vessels too. When taken in combination with other essential nutrients, evidence has shown that vitamin C can slow the progression of AMD and visual acuity loss. Vitamin C can also lowers the risk of developing cataracts.

Good sources of vitamin C are: oranges, orange juice, grapefruit, spinach, bananas, apples, and peaches.

Vitamin E

Vitamin E isn’t just great for your skin, it is a powerful antioxidant for your eyes too. It helps promote the health of cell membranes and DNA repair. It not only helps promote a healthy immune system, it can also slow the progression of AMD and visual acuity loss when taken in combination with other essential nutrients.

Make sure to get your intake of vitamin E by eating the following foods: sweet potatoes, almonds, sunflower seeds, peanuts and peanut butter.


Dietary fats like DHA and EPA are necessary building blocks of fat molecules. They are important for visual development and retinal function. In fact, low levels of DHA and EPA have been linked to dry eye syndrome and associated with eye diseases such as AMD and diabetic retinopathy.

In order to get your share of DHA and EPA, eat: tuna, salmon, mackerel, trout, anchovies or scallops.


Zinc is an essential trace mineral that helps your eyes by slowing the progression of AMD and visual acuity loss. It is known as a helper molecule because it helps bring vitamin A from the liver to the retina in order produce melanin. Melanin is a protective pigment in the eyes. This mineral is recommended for individuals who are diagnosed with a high risk for AMD. Deficiencies in zinc has been linked to impaired vision, poor night vision, and cloudy cataracts.

Some zinc rich foods are: lobster, beef, pork, yogurt, salmon, milk and eggs.

For more eye nutrition tips, make sure to speak with an eye doctor. An eye doctor can assess what is best for your eyes and health.

Common Eye Myths

Posted by CooperVision on Monday, June 18, 2012

Many patients may have heard lots of advice from their parents to eat carrots for great vision, and not to read with poor lighting, but do they know which pieces of advice are actually eye myths? Here are some common eye myths debunked:

Sitting in front of the TV or computer will harm your eyes

While patients who do this will experience eye strain, the pain is temporary. It is painful because patients are not blinking as often as they should when they are looking at a screen for long periods of time. Not blinking enough can lead to dry eyes. Doing the 20/20/20 rule can help alleviate the painful effects of dry eye. Every 20 minutes, take your eyes off your computer and look at something 20 feet away for at least 20 seconds. Some other solutions for dry eye are to blink often and use artificial tear drops.

Eating carrots improve your vision

While diet can certainly help improve the health of a patient’s eyes, eating carrots does not enhance vision. Vitamin A defiency is linked with poorer vision, but an abundance of the vitamin will not ensure eagle eyes. Some super foods to eat for healthier vision are: leafy greens, egg yolks, and nuts.

Reading in dim light ruins your vision

While reading with poor lighting can give patients a headache and some eye strain, it won’t worsen their vision or damage their eyes. However, for reading comfort, it does help to read with a bright light. Eye strain from reading in dim lighting may result in a number of physical effects including sore or itching eyeballs, headaches, back and neck aches and blurred vision. None of these symptoms damage a patient’s eyes, and the effect eventually goes away.

Wearing eyeglasses or contact lenses makes you dependent to them

Using vision correction does not accelerate the deterioration of a patient’s vision. Patients may notice that as they get used to clearer vision with their contact lenses or eyeglasses they will use them more, but it does not make them dependent on vision correction.

If you’re a eye care patient who needs a possible eye myth debunked, make sure to talk to an eye care practitioner near you.

Women’s Eye Health and Safety Month

Posted by CooperVision on Thursday, April 12, 2012
April is Women’s Eye Health and Safety month.More women suffer from visual impairments than men. Women are more susceptible to eye health issues because they tend to live longer than men. Women are also affected by hormonal factors, according to the National Eye Institute. The NEI states that of the 3.6 million Americans age 40 and older who suffer from visual impairment, including blindness, 2.3 million are women. Some other risk factors for visual impairment in women are age, smoking, poor nutrition, obesity. How can women ensure that they have optimal eye health? Here are some tips:
  • See An Eye Care Practitioner
  • Women should make regular eye exams a part of their health routine. Prevent Blindess America recommends everyone receive a comprehensive eye exam by age 40, if not earlier, and follow up care as recommended by an eye care practitioner. You can locate an eye care practitioner near you with CooperVision’s Find A Practitioner tool.
  • Learn More About Dry Eye
  • According to the National Women’s Health Resource Center, dry eye affects an estimated 3.2 million American women and 1.6 million American men over age 50. Hispanic and Asian women are more likely to be affected by symptoms of dry eye syndrome. If you are a woman who suffers from dry eye, make sure to ask your eye care practitioner about CooperVision’s Proclear lenses . They are the only contacts with FDA clearance for the claim: "may provide improved comfort for contact lens wearers who experience mild discomfort or symptoms relating to dryness during lens wear."
  • Eat For Eye Health
  • Women should eat a diet that is rich in vitamin C, vitamin E, beta carotene, lutein, zeaxanthin, zinc and omega-3 fatty acids to prevent vision loss from eye disease. For more information on eye health, make sure to visit our Facebook Timeline and follow us @CooperVision on Twitter.

11 Tips to Help Keep Your Eyes Healthy in the Digital World

Posted by CooperVision on Thursday, March 3, 2011

Our eyes are increasingly strained in today's digital world. Here are 11 tips to help keep your eyes healthy:

  • Get an annual eye exam: The only way to monitor your vision health is through annual exams by an eye care professional.  Let your doctor know if you are a “heavy user” of technology.
  • Abide by the 20/20/20 Rule:Take a 20 second break after every 20 minutes of use. Make sure you shift your vision to something in the distance (at least 20 feet away) during this break. If your work area is small, even looking out the window will allow your eyes to relax.[1]
  • Screen Placement: Keep your monitor at least 25” away from your eyes, preferably more.[2]
  • Monitor Tilt: Tilt your computer screen so that the top is slightly farther away from you than the bottom.[3]
  • Lighting: Reduce eye strain by using ceiling-mounted, indirect lighting and control outside light with blinds or shades.[4]
  • Font size: Reduce eye strain by enlarging the font. [5] Most hand-held devices and phones have a feature to increase font size when reading emails and text messages.
  • Adjust Display settings: Set your screen settings so the background blends easily into your surrounding environment.  Adjust the brightness and contrast so that on-screen images and letters are easy to read.[6]
  • Minimize Glare: Consider using an anti-glare film on your monitor or hand held devices.[7]
  • Upgrade to an LCD: Older CRT monitors are more likely to cause strain on your eyes than a liquid crystal display (LCD). [8]
  • Remember to Blink: We tend to blink less often when using a computer, so remember to blink frequently during continuous digital usage. Blinking will keep your eyes moist and prevent you from developing dry eye. [9] [10]
  • Find the right vision correction solution: Choosing multifocal contact lenses may help you see near, far, and everything in between. Whether you’re starring at a computer monitor or using your handheld device, multifocal contact lenses provide exceptional vision at any distance.
