Please choose the correct ending to complete the given sentence: Health: [header] How to get better vision [title] Try the bates method. [step] 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.

Ending1: 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. Ending2: [substeps] 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. Ending3: [substeps] Start by repeating bates each time you fall asleep. In this way, you strengthen your eye muscles and improve vision. Ending4: It is essentially the same exercise, except it uses different techniques. This method involves you slowly noticing things you don't see.
