Popular black pinhole glasses for blurred vision JT-C301 RoHS

 

 

Many people who have used pinhole glasses,for even a short time,comment on how more relaxed their eyes are and how they can see more clearly.Pinhole glasses are most suitable for activites such as sitting indoors and outside,reading,akiing,computer work,and watching TV.

 

 

The Science of Pinhole Glasses: 

 Pinhole technology is not a new discovery far from it. As far back as the 5th Century BC, the ancient Chinese people discovered that light passing through a tiny pinhole makes an image on the background it falls upon.

 

Theory:

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.

 

 

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.
