Bifocal Pinhole Glasses

With this type of pinhole glasses, the dot grid in the upper viewing area of the curved lenses is smaller and denser, while in the lower viewing area it becomes larger and coarser.

This enables a dynamic change in ‘focus’ between relaxing (small holes) and training (large holes).

Many years of experience show that bifocal pinhole glasses are preferred by people with more than 3.0 dioptres.
