Please, try to remember the approximate location of the three chosen objects, so that, after opening your eyes, you will be able to look immediately and directly in the direction of the object and focus it.
All exercises should of course be made without glasses.
So, here is how to do the Three-Point Exercise:
Find three contrasting objects at a distance of about three, 15 and 50 meters.
If your vision is very bad, so look for objects even closer to you. The first object should be near enough, so you can see it reasonably well.
Now close your eyes for about 3 seconds, relax, and then open your eyes quickly and look in the direction of your closest object without blinking. Once you blink, your eyes will relax, and the exercise will have no effect. So please do not blink!
See the first object for about 3 to 5 seconds. Try to look at a distinctive point of the object. Then close your eyes for three seconds, and move your head in the direction of the second object. Look at this again for about 3 to 5 seconds. Close your eyes and turn your head in the direction of the object, which is farthest away from you. Look at it for a few seconds, then close your eyes and relax again.
Now proceed with the exercise again three more times as a I have described above.
