Pinhole Specs - See Without Lenses. Download my pinhole specs plans from the "Related link" below and print on thin cardboard to create your own pair of pinhole specs.
Have fun with pinholes even if you don't have poor eyesight. Pinholes can improve poor eyesight or reduce the minimum focus distance of someone with good eyesight. With pinholes only the central light rays pass through the eye lens, these are not bent by the eye lens and so a clearer image is projected onto the retina. In this video pinhole specs were used with a defocused camera to simulate the before and after effect of seeing with pinholes.

Thanks, that was fun!
I'm wearing them as I type. I actually have a pair of commercial ones, but these work better! I find that the best way to make the pinholes is to use a thumbtack and poke through the cardboard into a bulletin board.
