This listing is for 2 pairs of Pinhole Glasses for Improving Vision and Reducing Eye Strain
Features:

Even ophthalmologists use small hole equipment to check eyes for refractive disorder. Also known as stenopeic glasses, these eyeglasses have a series of pinhole-sized perforations filling an opaque sheet of plastic in place of each lens.

Small hole glasses do improve vision for suffering with refractive error eye disorders, even ophthalmologists use small hole equipment to check eyes for refractive disorder. Frequent substitute of prescription glasses(TV, computer, reading) with small hole glasses will result in improved vision, natural and drug-free.
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 resulting image becomes sharper. However, a second effect may appear at the common bridge between each two adjacent holes, whereby two different rays of light coming from the same object (but each passing through a different hole) are diffracted back toward the eye and onto different places on the retina. Frequent substitution of prescription glasses (TV, computer, reading) with pin-hole glasses such as these will typically result in improved vision.
