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.

DHA/EPA

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

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.

Essential Eye Tips For Spring Outdoor Activities

Posted by CooperVision on Tuesday, April 24, 2012

Now that spring is in the air, it is the perfect time for outdoor activities for many patients. But what do patients do if they want to be active but they need vision correction? Patients who wear eyeglasses may worry about them fogging up, breaking, or falling off their face while they are active.

For active patients, contact lenses may be a better alternative. Contact lenses allows for a wider field of peripheral vision, a greater array of protective eyewear, zero distortion of images, and optimal vision correction from all angles of gaze. While there are plenty of benefits of contact lenses for an active patient, there are still commonly asked questions about contact lenses and outdoor activities that an eyecare professional can answer. Here are some common questions about vision correction and outdoor activities:

What can I do to protect my eyes from UV rays?

An eyecare professional may recommend contact lenses with a UV tint. It is important to remember that while a contact lens may offer UV protection, it is limited to the area of your eye covered by the lenses. It is crucial to wear sunglasses with UV protection in order to ensure complete UV protection of the eye area. CooperVision offers a variety of contact lenses with a UV tint. You can learn more about CooperVision’s contact lenses here.

What do you recommend for overnight outdoor activities?

For convenience, daily disposables such as Proclear 1 Day contact lenses may be a good choice because it removes the hassle of having to remove or clean lenses at night. Wearers simply remove them after a day’s wear. There is no need to worry about lens storage. An eyecare professional can determine which patients are good candidates for daily disposables. For more in depth questions about contact lenses and outdoor activities, patients should talk to an eye care professional.
