1. Rub your palms for 2 minutes and place them on your eyes gently, not pressing the eye balls. The warmth from the palms will relax the nerves in the eyes and help in blood circulation. Keep your eyes closed inside and see to it that minimal light passes through your palms.  
2. Eye stretching; close both eyes firmly and open them suddenly stretching your face too. 
3. Shut your eyes and rotate them in all the directions slowly and steadily concentrating on one eye at a time.
4. Sun bath is also good for eyes. Don’t look directly in the sun. Concentrate on your eyes while performing this exercise. Look both sides, up to down, diagonally and try to stretch your eyes to allow more sunlight in your eye.
