Pilot Black Unisex Pin hole Eyeglasses for Eye Exercise and Eyesight Improvement Plastic

Pinhole glasses, also known as stenopeic glasses, are eyeglasses with a series of pinhole-sized perforations filling an opaque sheet of plastic in place of each lens. Similar to the workings of a pinhole camera, each perforation allows only a very narrow beam of light to enter the eye which reduces the size of the circle of confusion on the retina and increases depth of field. In eyes with refractive error, the result is claimed to be a sharper image.

While normal glasses encourage the eye to become lazy, the pinhole type encourage the ciliary muscles to become stronger, pulling the lens into the correct shape. This is based on the view that the eye can be made to adapt to its environment and can be encouraged to change shape towards normal.
