KF-287A and KF-287B and KF-287C Relax pinhole glasses
The glass helps to relax the eyeball muscle, and adjust eye focus.

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.

You can feel the relaxation once you ware it and afterwards.

Good and simple eye relaxation for a large population whose job causes

tired eyes: students, teacher, white collar, computer users.. age from

child to aged people, etc.
A Safe, relaxing and completely, natural vision training technique.

Many people who've used pinhole glasses, for even a short time, comment

on how more relaxed their eyes are and how they can see more clearly.

Pin Hole glasses are most suitable for activities such as sitting

indoors and outside, reading, computer work, and watching TV.
