The other day I found a video that claimed you could make your vision clearer without glasses just by looking though a small pin hole. It claimed that if you made a tiny hole using your fingers and look through it, you would be able to see clearly.
As someone who wears glasses for distance, this seemed very far fetched but I decided to give it a try. I took off my glasses, made a tiny hole to look through and then looked at some blurry text in front of me. Sure enough it actually worked! Now it is not perfect and it is certainly not as clear as with glasses, but it made the text clear enough to read compared to without this method when it was completely blurry.
Apparently this method works by limiting the amount of light that get through so there is not as much that is focused on different parts of the eye. Because of this, the light that does get through the small hole is more focused and more clear.
I was so impressed by this trick I decided to make my own little pair of pin hole glasses. Well they are not really glasses, but more a credit card size piece of cardboard with 2 small holes poked it in. I spaced them out about the right width so I could look through with both eyes at the same time. This is a bit difficult especially when trying to see things at different distances so sometimes it is easier to just look through one hole and close the other eye.
I put this card in my wallet to carry with me at all times in case of an emergency. If I were to loose my glasses for whatever reason and needed to see something clearly in the distance, I could take out the card to use as a quick replacement for the glasses. If you wear glasses, I would highly recommend trying this technique so you can use it if you ever need to see something without glasses.
