For good eye sight, it is important to maintain and preserve the visual function throughout one’s lifetime.
Diet: For healthy functioning of eyes, one needs sufficient quantity of vitamin A, green leafy vegetables, fruits, milk, eggs, meat (especially liver). A balanced diet with right proportion of proteins, carbohydrates and fats will help in keeping eyes healthy. For infants, mother’s milk is very important. It is during the time of weaning, that infants can develop vitamin A deficiency that may lead to a permanent impairment of vision.
Hygiene: Keeping eyes clean is important to ward off infections. First thing in the morning is to clean the eyes in running tap water. Do not splash water into eyes since it can result in an abrasion and the lids close as a reflex action without any cleansing being achieved. One should clean the after coming back from outdoors as well as before going to bed. It is equally important to have good hand hygiene. Do not touch your eyes with dirty, greasy hands. Make sure you sanitize your hands at regular intervals.
Desk jobs: Jobs are getting oriented around computers and laptops, it is important to take few precautions:
1. Computer screen should be kept 30-50 cm away from eyes.
2. Top edge of the screen should be in line with eye level.
3. The chair should be ergonomically designed for comfort and correct posture.
4. Take a break every 20-30 minutes to walk 20 paces, look beyond 20 feet and blink completely 20 times.
5. Increase font size for comfort and adjust picture quality for comfortable viewing.
6. White background generally gives less strain as contrast is more.
