Following exercises are advised for the improvement of vision:
1. Palming: Sit comfortably on an arm-chair. Close the eyes and cover them with your palms gently, crossing them over each other, leaving space for the nose to be open. Keep the eyes covered loosely and resting with elbows placed on the arms of the chair. Remove the hands after 5 minutes.
2. Swinging: Stand upright, with feet a foot apart. Keep the hands loosely at the sides and be relaxed. Gently sway the body keeping it straight from one side to the other, swaying like the pendulum of a clock, moving slowly.
When swinging to the right, raise the heel of the left foot and vice versa. No bending of the waist. See through the window while swinging, so that the window moves the opposite way to your movement.
After a minute, close the eyes and swinging with eyes closed imagine that you are seeing through the window as before and observing the same movements. Open the eyes and repeat this exercise a few number of times.
3. Blinking: Our eyes blink normally, but when diseased they get fixed and do not blink so often. Thus to restore their blinking capacity, practice blinking consciously, whenever or wherever possible. Even when reading, if you feel some strain do this and you will feel relieved.
4. Sunning: Getting the sunshine to heat up your eyes is a good and useful exercise. Face the sun with closed eyes. Let the rays of the sun fall equally on all parts of your face, which can be done by moving your face from side to side gently.
Do it for 5 to 10 minutes and 2 or 3 times even during the day, though sunshine during the forenoon is said to be more useful.
5. Splashing: Sit on your feet in the bath-room, little leaning in front of bucket of cold water. Fill your mouth with water by a mug and close your lips, with mouthful of water. Get another mug full of water and go on splashing on the mouth full of water with eyes closed.
Then drop the water from the mouth and rub your face with your hand to warm up the mouth/face. Repeat the exercise by filling water in the mouth again splashing, dropping out water and rubbing a number of times.
This is highly useful, not only for the eyes, but also for saving yourself from catching cold, if done in the morning right after getting from bed. The circulation of blood created in the face at the touch of cold water gives the cure.
6. Gazing: Concentrate your gaze on your index finger extended outwards and try to view a distant object across it, as if taking an aim. Repeat it a few times.
7. Shifting: When sitting, allow the eyes move up and down a number of times. Then move from side to side, then circulate and then in the reverse direction, all movements a number of times. These will strengthen the muscles of the eyes.
