Hello, you should do these following exercises to strength the ocular muscles:-
Warm your eyes. Rub your palms together to create heat, and then place them against your eyes for five seconds. Repeat this three times.
Roll your eyes. Start by looking up and then slowly circle 10 times clockwise and 10 times counterclockwise.
Focus. Hold a pen at arm's length, focus your eyes on it, and slowly bring the pen closer until it's about 6 inches away from your nose. Then slowly move it back, keeping your eyes focused on the pen, 10 times in all.
Massage your temples. Using your thumb knuckles, massage your temples in small circles, 20 times in one direction and 20 in the other. Repeat the same actions above the mid-point
of the eyebrows at the forehead, then below the eyes on both sides of the bridge of the nose.
Take a mini-nap. Put your head
back, close your eyes, and relax for 3 minutes.
Insufficient sleep may weaken your vision, so shoot for 8 hours of sound sleep a night.
Rest your eyes 10 minutes for every 50 minutes spent reading or in front of the computer. If your eyes feel overly tired, lie down and place cooling cucumber slices over your eyelids.
Take homoeopathic medicine which will help you in preventing rather reducing the power of your eyes. Take Physostigma 6/ thrice daily for 1 month. Thereafter, revert back for further guidance.
