Pinhole glasses are eyeglasses with a series of pinhole-sized perforations filling an opaque substance such as metal or plastic in place of each lens. The user looks through any of the many small holes in the material. These holes have the effect of reducing the width of the bundle of diverging rays coming from each point on the viewed object.

Traditional pinholes have flat or slightly curved lenses of plastic with actual holes punched through them. Ultraviolet light is reduced because the holes restrict the amount of light that reaches the eyes.

Modern pinholes have solid, curved lenses of the same clear plastic used for prescription glasses. The lenses provide full untraviolet protection. The pinhole pattern is printed on the back in ink and a mild mirror coating is added to the front to help hide the pinhole pattern from others. These revolutionary pinhole glasses were developed by Caribbean Eyes and are availabe nowhere else in the world.

Pinhole eyeglasses work by allowing a narrow beam of light to enter the eye through these small perforations. This helps to reduce the size of the circle of confusion that is placed on the retina of the eye and can help to increase the field of depth in your vision. These glasses reduces brightness and peripheral vision,a part of vision that occurs outside the very center of gaze.So it should not be used while driving or while operating machinery. These glasses are not recommended for people with over 6 diopters of myopia, that is near- or short-sightedness where they see nearby objects clearly but distant objects appear blurred.

Pinholes do not have to be cleaned of fingerprints and other marks that affect vision. There is no need to continually throw away old glasses and buy new, stronger ones. Unless the pinholes break, they can be used an entire lifetime. Multi-focal lenses provide a continuously variable curve that is supposed to give good vision at all distances. In reality, the distortion on either side of the center line is considerable and often too great for comfortable use. Pinholes eliminate this problem.

The eye doctors and the optical industry make a determined effort to take pinhole glasses out of the hands of the public. They have even pressured the US government to conduct armed raids on pinhole suppliers and destroy their inventory.They see inexpensive pinholes as a threat to the lucrative business of selling overpriced prescription glasses and sunglasses. That is why one does not find pinholes for sale in optical stores.

Mike has been writing and publishing articles about health products. He recently came across a website on pinhole glasses which gave information about this old technique of using pinhole glasses for eyesight correction. Here's an article about pinhole glasses.
