Minimal help: Pinhole glasses will clear up any refractive error so your nearsightedness will improve. But the down side, other than the weird appearance, is that there is a massive drop in the total light input and a restriction in the peripheral field of view, so the pin hole glasses are a good diagnostic test but not a practical solution. ...Read more
I lost my glasses and I don't even know how I lost it, but I have pinhole glasses. Can I use this in my school? It improves my vision?
Sometimes: If the reason for your poor vision is a refractive error (i.e., can be corrected with glasses), then many times pinhole glasses can improve vision. The reason is that the pinhole only lets one ray of light through a hole, so there is theoretically no focal point where multiple light rays converge, and thus the single ray is 'in focus' at any point along it. They don't work for cataracts, etc. ...Read moreSee 2 more doctor answers

A person would have better focus only while wearing the glasses, but the above side effects make pinhole glasses impractical. ...Read moreSee 1 more doctor answer
