Cataract and macular degeneration are the eye disorders that generally develop due to ageing. The production of unstable molecules known as free radicals increase with age, this could damage healthy cells. So cases of eye damage and disorders like cataract and macular degeneration increases with age.
In cataract the transparent eye lens yellows, hindering the passage of light rays through it making the vision hazy, cloudy, or blurry. The lens becomes completely opaque causing blindness if the patient does not get treated. Although cataract develops in older adults it can occur at any time of life. Smoking and diabetes can be made responsible for hastening the development of this disorder.
Diet rich in vitamin C and E and the carotenoid lutein may slow the progression of this disorder.
Another eye disorder macular degeneration is a gradual, painless, deterioration of the macula which is the tissue in the central portion of the retina. Blurring of the central vision is the first symptom of this disease. The cause of this disorder is not known. Recent studies suggest that a diet high in antioxidants may prevent or slow down the disorder.
Antioxidants lutein and zeaxanthin may help in this disease. One can get lutein from food sources like corn, peas, broccoli, kale, Swiss chard, water cress, green leafy vegetables and egg yolk.
Zeaxanthin could be obtained from greens, red peppers, and corn. Taking diet high in saturated fats increases the risk of age related macular degeneration. Eating fish once in a week may reduce the risk.
This disorder is found in diabetics. It is the infiltration of the retina with tiny ruptured blood vessels. Taking antioxidants, nutritious food and maintaining blood glucose level reduces the risk of diabetic retinopathy.
This deficiency disease caused by the deficiency of vitamin A is rare in western world but it still exists in many underdeveloped countries due to poor diet and less knowledge about the disease. In this disease the patient faces difficulty in seeing well in dim or insufficient light. The impaired ability of eyes to adapt to darkness leads to night blindness or poor night vision.
The causes may be vitamin A deficiency or inability to utilize it properly.
Beta-carotene which gets converted into vitamin A in body can be helpful. Sources of beta-carotene are dark yellow or orange fruits and vegetables such as carrots, sweet potatoes, apricots, papaya, and dark green leafy vegetables.
Organ meat, dairy products, fortified butter margarine are some good source of vitamin A.
