The Pinhole Glasses are believed to help train your eyes to focus. The brain will give the order to your eyes to focus within the holes, thus exercising the eyes' focusing muscles. Just wear them for 5 minutes a day for the first few days. Once you are used to them, try wearing them while watching TV or reading, and you will be amazed at the effect. They come with instructions on how to carry out various exercises which will help to strengthen the eye muscles.

The unaided weak eye

In the weak eye, light rays entering the eye's lens are not focused onto the same place on the retina. For example, rays a, b, f, g, require more focusing by the lens to hit the same plane as rays c, d, e.

This clear image is flooded by the blurred image known as the "blur circle".

The unaided weak eye with Pinhole Glasses

When the pinhole lens is introduced, only rays c, d, e, are allowed to form an image on the retina and therefore no blur circle is formed. Consequently by using a lens with multiple pinholes, many focused images form on the retina and a clear natural image is seen.
