* Use face wash instead of soap because soap tends to darken the skin on the eyelids.

* Do not read continuously in moving vehicles.

* Do not stare too tong at anything without blinking the eyes. Blinking provides lubrication and relief from light.

* Do not rub the eyes too hard.

* To give momentary relief to the eyes, close the eyes with your palms so that no light can enter. Now open the eyes in the palm cup and stare into this darkness for a minute.
