Pinhole glasses look like sunglasses but instead of lenses they have a sheet of thin perforated plastic. These tiny holes each allow a very thin beam of light into the eye, which eliminates the scattering of the light and reduces the circle of confusion (or blur) on the retina. Pinhole glasses can help a wide range of eye problems, such as myopia, hyperopia, presbyopia, astigmatism, cataracts, Eye strain (from computer screens) The pinhole glasses are supplied with a drawstring pouch.
