Lost your glasses? How to See Without Glasses.

Have you ever wanted to read a sign in the distance but it’s just too blurry to read? Maybe you have glasses but you’d rather not dig them out of your bag. Here’s a trick for you.

This well-done Minute Physics video on YouTube shows us a simple tip that allows us to focus our eyes if we don’t have our eyeglasses (lenses) handy. It also explains vision very well.

The key or trick is a pinhole. I once had a pair of glasses that were full of pinholes and were to retrain the eyes to focus. They worked to allow clear vision without glasses, but I didn’t try the retaining but just got them because they were interesting. This is the same physics.
