Visual Impairment: Prevention and Corrective Measures

Is the problem serious?

Yes, it is. Based on the numbers released by the Centers for Disease Control and Prevention for individual states, almost 10-20% of the American population above 40 years has at least some degree of myopia. On the hand, 18-41% of the population in the same age group was reportedly far-sighted. The number of people affected by one or the other form of visual impairment worldwide is estimated at 140 million and counting.

So, what causes vision impairment?

Age-related macular degeneration is the leading cause of weakened eyesight. Other responsible factors are damage to the eye tissues by free radicals or UV rays, habit of reading in improper light, prolonged use of computers, watching television in close proximity, improper eating habits, and genes.

Can diet help?

Certainly! Vitamins A, B (Group), C, D, and E are all known for their salutary effects on eye health. In addition, nutrients, such as zeaxanthin, lycopene, lutein, zinc, and certain fatty acids are essential for protecting eye tissues and maintaining good vision. Include veggies, such as lime juice, cabbage, carrots, pumpkin, garlic, corn, green vegetables, and onion in your daily meals. Consume fresh fruits or fruit juices of papaya, apricots, watermelon, avocado, grapefruit, black currants, guava, and blueberries. Foods rich in antioxidants, including bilberries, red grapes, tomatoes, spinach, and broccoli should be consumed at least once a day. One of the finest sources of omega 3 fatty acids is fish oil, particularly, cod liver oil. Further, other animal products, like eggs, milk, and white meat truly complete the balanced regular diet.

What if I am too busy to arrange for balanced meals?

This is a common problem these days. Perhaps, this is the reason why dietary health supplements are gaining ground like never before. There are options of allopathic vitamin and mineral supplements, as well as, those of traditional herbal formulations. Nearly all the nutrients required to prevent and correct vision impairment are available as over-the-counter drugs in the form of soft gels, capsules, tablets, liquid tonics, and other infusions.

That said, you still need to take out some time for simple eye exercises on a regular basis. These exercises do not take much time and can be taken up absolutely anywhere. Consult your physician for more guidance.
