I have been occasionally using pinhole glasses for reading and computer work for about 35 years. They keep your eye muscles strong and I believe help to keep the lens circular. I am 69 years old and just got my first set of mild prescription glasses (1.5 mag) from an ophtalmologist a couple months ago.
As a follow-up, don't use the pinhole glasses while driving because you lose a lot of your peripheral vision.
This works and has been used by Eskimos with their traditional snow goggles with the narrow slit for peering through. You can also buy glasses with black lenses but dotted with pinholes - they work very well and are called pinhole glasses. The results are immediate but they will also improve your vision if worn regularly. I've also seen plastic fashion glasses that are similar to pinhole glasses in teen fashion shops that are less expensive.
oh so true. our dad used to make us look at moon thru the hole in the needle (the small upper portion where the thread goes in)..... it improves eyesight.
This is amazing. The way to improve (I'm afraid to say completely cure) your eyesight is to do this: Peer thru a small hole the size of a pencil lead width. Use a card or your hand. Look thru and you will see your eyesight is perfect! Not sure exactly why it works but if you use it to exercise your eye, it will improve your eyesight dramatically. You can even feel your lense contract as it works to adjust itself. It works quickly and 5 minutes a day for a couple of weeks will do the trick. Then just as needed after that to keep them eyeballs in shape! And if you ever forget your glasses, peering thru a pinhole will do in a pinch.
They sell what are called pinhole glasses online (cheapest on ebay) but they are too dark, I don't like them much. But the idea is they help you improve/exercise your eye!
