Pinhole eyeglasses are also known as stenopeic glasses. Stimulating the muscles around the eye, glasses with holes in the lenses allow you to improve the quality of vision, this is the difference with traditional eyeglasses. Glasses with pinholes serve as re-educational eyeglasses; they lead the eye to move quickly from one hole to another and teach a different and more effective use of sight. Pinhole eyewear works in a similar way to that of a pinhole camera: glasses with little holes allow only a very small portion of light to enter the eye. This fact reduces the size of the circle of confusion on the retina and helps increasing depth of field. The fact of being able to see better through eye glasses with pinholes makes it easier to use them.

Pinhole glasses with holes to improve eyesight also protect your eyes from excessive exposure to light and in some cases can be pinhole sunglasses, but they do not have UV screens.

HOW TO USE PINHOLE GLASSES

Use is recommended during activities such as reading, watching television or computer screens, and to re-accustom the eyes to light. The use of the pinhole glasses, glasses with holes, must be constant for at least six months; this period is necessary for adaptation, which is gradual and varies from a person to another. Pinhole glasses improve vision: the result of wearing them on eyes with refractive error is claimed to permit a sharper vision of the image. However, sometimes wearing glasses with holes in lenses may appear a second effect, which is double vision (this means objects having doubled edges), it can make the entire image tiring to look at for long periods of time.

The stenopeic glasses with small holes should not be used when making fast movements, or in potentially dangerous situations or when there is not sufficient light. Do not use when driving. Eyeglasses with holes in them should not be worn in this situation.
