Myopia Prevention Pin Hole Glasses for Teenagers

The glasses are suitable for both adult or children who has the problem of myopia, hyperopia, and astigmatism.Theory is very simple: when the eyes can only look through the small holes, they naturally change focus to a relaxing standard, so that the eyeballs are relieved from the previous nervous focus.
Wearing for 15 minutes one day will help to improve your eyesight within 2-4 weeks.

Look at this drawing of a myopic eye with a pinhole lens in front of it. You will see that the eye does not need to deal with the rays that would need the most bending since they are blocked by the lens.
