Unless those exercises can change the shape of your eye, which is why one can't see clearly, exercises do nothing except strain your eyes.
rwfromkansas, you're correct...it's the shape of my eyes that have affected my vision. My Dr had me try this to prove it...
Place your index finger on the very corner of your eyelid at a point that would contact the eye itself. Now, gently, push your finger in the direction of your eye while, at the same time, trying to read from a magazine. Notice anything?
