I am going to try some Yoga eye exercises. My son's girlfriend suggested it because it also calms you down so you will not be so stressed. Best of luck to you. Double vision is not fun it is stressing.
Some exercises in Bate's method like eye palming,blinking,focusing more on distant objects etc will be useful to all,as it helps to relax eyes which we fail to do most of the time.
Works for some, check out yoga for your eyes. The guy went from practically blind, to driving a car seeing. I think it can work for some things, but not everything obviously. These are simple eye movments, and i dont see how they can do any harm to your eyes. Good diet and healthy lifestyle is probably your first key to healthy eyes.
I am note sure it works. No personal experience.
