Trayner pinhole glasses consist of conventional spectacle frames with the lenses replaced by opaque screens containing lots of small holes. Looking through the pinholes immediately makes blurred vision sharper. This can help people learn to focus where they had previously needed glasses.
How do Trayner pinhole glasses Work?
When the eye receives a blurred image it moves the focus, looking for a sharper image. If this is not found the eye is left unfocused. With the Trayner pinholes the image is slightly clearer so the eye can learn to focus again exercising the focusing muscles. With regular practice the eyes are able to see more without glasses.

It is clear that anything that can reduce this accommodative effort, including pinhole glasses, is a useful weapon in retaining good vision. It is for this reason, and the fact that those in the optical business want nothing to do with them, that we have decided to promote the use of pinholes on this Blog. These glasses could be a major tool in preventing myopia. Pinholes are harmless; minus lenses MUST be avoided.
