There are exact exercises to restore eyesight naturally and it you want to know how to improve sight without glasses there are exercises that will get you started by removing eye strain which on its own serves to continually damage your eyes. Staring and straining are the worst things you can do to your eyes.
In order to do this exercise all you will need is some reading material like a newspaper or book and someplace where you can get some peace and quiet.
This exercise is called the dot exercise. Find a full stop or comma on the page and try to make it as clear as possible. In an attempt to make it come into focus, stare at the comma for a moment. You will probably find that it becomes less clear the longer you stare at it. This is due to the fact that staring or straining do not allow your eyes to relax which is essential to enable your eyes to work at their best.
Now, relax your eyes. Close them for a moment. Then, without straining, look at the comma, do not stare at it, rather slowly move your eyes around its general position on the page. The important thing here is that your eyes need movement so do not focus on the comma. Remember to blink as normal. Close your eyes and picture the comma and then look at it again. Once your eyes have relaxed, you will find it much easier to see the comma.
