How to get better vision
Try the bates method.
Some people believe that our eyes are like the rest of our body-the more we exercise and use them, the stronger they will become. The bates method uses this idea and a series of exercises to gradually improve your vision.

Possible answers:
(A). All you are asked for is to highlight the whites of your eye and make your vision stand out more instantly. You should also strive to lose 37 pounds in a year, at minimum, before you begin training for the bates methods.
(B). While there is no scientific evidence that the bates method works, people in surveys do report improved vision. Eye exercises may be what is called a " placebo " effect-that is, practitioners report feeling better because they believe the exercises are helping.
