    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.

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.
