Glasses and contact lens often are bad for your eyes. You fall into a trap where you no longer use the focusing muscles in your eyes the way you should be. This important muscle begins to weaken, requiring visits to your eye doctor for stronger and stronger glasses. That makes your eyes lazy and weaker with time. Pinhole glasses are the solution. They are also known as stenopeic glasses. They are eyeglasses with a series of pinhole-sized perforations, filling an opaque sheet of plastic in place of each lens.

Unlike conventional prescription glasses, they produce a clear image without the pincushion effect around the edges. This makes straight lines appear curved. So they reduce the size of the circle of confusion on the retina and increases depth of field. The result is a clearer image, especially in eyes with refractive error. Another result is delaying the need for glasses as you age and an improvement in your quality of vision with time. All of this is because each perforation allows only a very narrow beam of light to enter ...
... the eye.

You'll really notice the difference when focusing in the middle to long distance, like when watching TV or reading from a classroom blackboard. Pinhole glasses are useful for people who are both near- and far-sighted. But they are not recommended for people with over six diopters of myopia. They also have some limitations to their uses. The amount of light entering the eye is reduced so it is strongly recommended that they are used in good lighting conditions. It's also important to know that pinhole glasses reduce peripheral vision and so they should not be used for driving or when operating machinery.

Pinhole glasses have been marketed by various companies on the claim that they could permanently improve eyesight when combined with certain eye exercises. These claims have been analyzed, but no scientific evidence has been found to support them. The claims are no longer allowed to be made in the United States under the terms of a legal settlement with the Federal Trade Commission.

Users of pinhole glasses report almost perfect vision. They have less difficulty reading words and seeing definition in a TV image without their prescription spectacles.


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. Mike himself had tried the product and found it quite beneficial. Here's an article about pinhole glasses.
