Question:
Does cupping both your hands round your eye improve you vision?
Answers:
The cornea, being a lens has a certain focal length. So alot of the use of eyeglasses is due to the shape of the eye being off slightly, and the image not focused properly on the retina. So, if you're pressing slightly on your eyes, that may temporarily change the shape of your eye slightly and bring things in focus. That said, I don't think it's a good idea to press on your eyes, or to do so repeatedly to get a better focus.
