Intro: Pinhole Specs

Pinholes can improve poor eyesight or reduce the minimum focus distance of someone with good eyesight. Download my pinhole specs plans and print on thin cardboard to create your own pair of pinhole specs. Plans for Pinhole SpecsWith 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.

this works just like a pinhole camera.
you can use it as a replacement for glasses but it wont let in much light.

Try resizing the image so that it is the size of an A4 sheet, that's 210mm x 297mm.

I use something like this when I shoot 3 gun bullseye , that way I only see the sights and the target and can keep both eyes open .....If you use these for shooting use safety glasses
