I see. So just like eating right, it's a matter of changing your lifestyle, not just something you 'cure' and keep doing what you were doing. Edit: With a little bit of practice I found an exercise that's effective. Here's the idea. If you're seeing something clearly up close, you're not training your eye on distant objects. And if you're looking at distant object that are too far away, it's not helping either because they're too far away. The exercise is to look at a piece of paper with printed text and move it away from you (or move your head away) until it starts to be come blurry. Then you move closer until you can read the text clearly again. Each time you do this you're "pulling" your vision a little bit out, like stretching a rubber band more and more. You have to identify which of your eyes is the weaker one and work on that one first until the two eyes are about equal. Just after half an hour of this exercise I already feel like my vision improved drastically. I'm thinking if I can incorporate some physical exercises into the routine so that it doesn't feel like I'm wasting too much time.
