Diet: For healthy functioning of eyes, one needs sufficient quantity of Vitamin A. The sources include green leafy 
vegetables, fruits, milk, eggs, and meat (especially liver). A balanced diet with a correct proportion of proteins, carbohydrates and fats in combination of these food items 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 on to 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 eyes after coming back from out doors 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:
- Computer screen should be kept 30-50 cm away from the eyes
- Top edge of the screen should be in line with the level of eyes
- The chair should be ergonomically designed for comfort and correct posture
- Take a break every 20-30 minutes to walk 20 paces, look beyond 20 feet and blink completely 20 times
- Increase font size for comfort and adjust picture quality for comfortable viewing
- White background generally gives less strain as contrast is more.
