About Pinhole Glasses

Overview

Pinhole glasses are made from lightweight perforated plastic lenses set in plastic or metal frames. They help people with refractive eye disorders that cause blurry vision such as nearsightedness or myopia, farsightedness and astigmatism (reduction of the quality of sight because of problems with the lens). Pinhole glasses also benefit the elderly and individuals with computer vision syndrome. They are available without a prescription.

History

The history of pinhole glasses goes back to 1573 when they was conceived by a scientist named Christoph Scheiner. In 1934, Charles C. Guthie of Pittsburgh, Pennyslvania, was awarded a patent for "lensless spectacles." The name pinhole glasses was given to these devices in 1934.

Function

According to Pinhole-glass.com, "it is now widely accepted that pinhole glasses do improve vision for those suffering with refractive error eye disorders." People with blurred vision don't see clearly because the light rays entering the eye, focus either in front of, or behind the retina at the back of the eye. Pinhole glasses work by allowing light rays to enter only the center of the pupils while blocking out all the rest.

How to Use

Wear pinhole glasses for five minutes each day for the first few days. Continue using your regular glasses or contact lenses for the rest of the time. Increase using your pinhole glasses for 15 to 20 minutes daily. As you get used to the pinhole glasses, the pinholes or any initial multiple vision will disappear. Use your pinhole glasses for reading and watching television. The glasses will naturally exercise your eye muscles and improve your vision.

Benefits

According to pinhole-glasses.com, using pinhole glasses will improve vision, clarity and resolution for refractive (light rays incorrectly focused on the retina) eye disorders. Pinhole glasses also increase object brightness in individuals with vision problems in low-light situations. Pinhole glasses are good for short, middle or long distance correction, so one pair meets all of these vision needs.

Warning

Bear in mind that because of restricted peripheral vision (side vision) of pinhole glasses, they should never be used for driving or moving about outdoors.
