How Diet and Nutrition Affect Eyesight

29 Nov

Sharon Kleyne, Founder of Bio Logic Aqua Research, announces new education about diet and nutrition, and its affect on eyesight. Sharon Kleyne interviewed Dr. Allen Taylor on March 21st, 2011 about diet, nutrition, water, and eyesight.

Dr. Allen Taylor, a chemist, became interested in eyesight while researching the molecular structure of the eyes’ cornea and lenses. The cornea and lens are living tissues but they lack blood vessels and when healthy, are absolutely clear so that light can enter the eye. This research led Allen Taylor to an interest in diet, nutrition and eyesight and to the Tufts University Laboratory for Nutrition and Vision.

According to Dr. Taylor, “There is more to food for the eyes than just carrots.” The goal of his food and nutrition research is to prolong vision. By taking care of your eyes and eating the correct “food for the eyes,” you can lessen the chances of age-related eye diseases such as macular degeneration, cataracts and chronic dry eye. Improved diet and nutrition also prolongs health and life.

Sharon Kleyne noted that age related macular degeneration is increasing and is expected to be out of control by 2030. The computer age is not helping. She also noted that water is one of the most important eye foods.

Allen Taylor stated that healthy food and nutrition, including water, can be helpful in natural sight preservation. His recommendations for eye health are the same as for overall health: Keep weight down, get plenty of exercise, drink sufficient water and eat five servings of fruits and vegetables a day for anti-oxidants and fiber. He recommends cutting down on most other foods. Also, free oxygen is harmful to cells and is removed by antioxidants. Free oxygen can also damage the heart and make the cornea and lenses less clear. Vitamin C is an excellent anti-oxidant.

Vegetables are best eaten raw but frozen or cooked vegetables are better than nothing. Juice is fine if there is no added sugar or additives. Sugar is associated with macular degeneration. Many meat proteins are modified in the body to sugars that accumulate interfere with absorption of beneficial proteins.

The role of sodium in eyesight, according to Dr. Taylor, is inconclusive. Too much sodium can be unhealthy but a certain amount is required for tears and perspiration.

Dr. Allen Taylor is a supporter of drinking plenty of water to avoid aging and dehydration diseases such as chronic dry eye. He is a supporter of eye misting to supplement natural tear film water content and help keep eyes healthy and well nourished.

Laser Eye Surgery Pioneer Marguerite McDonald, MD, Talks Computer Eye Strain

10 Nov

Laser Eye Surgery Pioneer Marguerite McDonald, MD, in addition to performing the world’s first excimer laser eye surgery in 1986, is a practicing Ophthalmologist on Long Island and Professor Emeritus at Tulane University. As a practicing Ophthalmologist, she has considerable experience treating dry eye, computer eye strain and computer dry eye.

On June 1, 2009, Dr. Marguerite McDonald was interviewed on the Sharon Kleyne Hour Power of Water, an Internet radio talk show hosted by Sharon Kleyne. The interview may be heard on World Talk Radio, Voice America, Green Talk Network, Apple iTunes and Amazon.com.

Computer Eye Strain

Dr. McDonald observed that computer eye strain is a common and rapidly growing complaint among her patients and that the number of patients who can no longer use computers as a result of computer eye strain and serious dry eye symptoms is also growing rapidly. Symptoms should always be taken seriously and alleviated when possible, both by soothing the eyes and by taking prevention measures.

Soothing computer eye strain

Dr. McDonald notes that rubbing is bad for your eyes. If dryness or itching of the eyes is caused by allergies, rubbing can further entrench the allergen and cause a release of chemicals that are even more uncomfortable.

For dry eye symptoms, Dr. McDonald recommends a cool, wet compress, lying down and relaxing, with eyes closed. Moisture from the compress will absorb into closed eyes and eyelid skin. Dr. McDonald also recommends Nature’s Tears EyeMist (a sponsor of the Sharon Kleyne Hour Power of Water) to soothe dry eyes. While performing eye surgery, Dr. McDonald has her eyes misted occasionally.

Predisposition

Dr. McDonald pointed out that many factors can predispose computer users to develop dry eye and computer eye strain symptoms. These include arthritis, Parkinson’s, scleroderma, Sjogren’s syndrome, allergies, numerous medications (especially blood pressure medications and anti-depressants), osteoporosis, gout, blink disorders, thyroid problems and the first few days after LASIK eye surgery.

Other factors affecting tear film moisture content during computer use include common office conditions such as indoor air, forced-air heating and cooling, cleansing fluids, detergents, poorly ventilated buildings and excessive computer use.

Preventing and alleviating

According to Dr. McDonald, the most serious eye problem associated with computer use and computer eye strain is reduced blink rate. The normal blink rate is 20 to 30 times per minute whereas somebody deeply absorbed in computer work may blink only three times a minute. This greatly increases moisture evaporation from the eye.

Dr. McDonald suggests keeping the computer screen low so that you have to look slightly down on it and therefore do not open your eyes as widely. She also recommends frequent short breaks to rest the eyes and regular breaks away from the computer. Also important are sleep, stress reduction, exercise, adequate daily water intake and a proper diet including eye foods such as dark green leafy vegetables and foods with omega-3 fatty acids. .
