Following tips may help:

Care of eyes

Wash the eyes using eye washing glass twice daily. Wash them after watching television, before retiring to bed, as u come home after a long tiring day outdoors, & also after reading for a considerable time at a stretch.

Method of washing the eyes

Take thick towel, rub the face with friction closing the eyes for two minutes & then wash using the eye-glass. Do this at least once in a day.

Fill the eye washing glass with pure water & cup the eyes in it. Blink inside the water 15 to 20 times. (In the absence of an eye washing glass ur palm can be cupped for the purpose.) Throw away the water & refill the glass with some more fresh water & wash once again. Repeat the same with the other eye.

Do not watch television unblinkingly.

Exercises for the eye
Do the following Eye Culture Exercises regularly to prevent & cure any disorder of the eyes:

After attending to the call of nature, wash the eyes in the eye washing glass, opening & shutting the eyes under cold water.
Practice deliberate blinking for five full minutes any time of the day.
