Product: Eye MASK　"Eye Balance" 　NAKAGAWA Method　 Supervised by Kazuhiro Nakagawa
Brand: Blueberry Inc.
Your vision starts to be poor because of the ciliary muscle (focusing muscle) tens. This is what happens every day when you stare at a screen for hours on end.
 EYE BALANCE are designed to help unravel ciliary muscle tension and develop the eye muscles. 
The small holes enable a much narrower beam of light to enter the eye. 
This allows the eye muscles to relax and focus the small beam of light more clearly onto the retina.

 First, Eye Balance is worn over naked eyes. 
Look at distant views that were difficult to see with naked eyes.
 You should be able to see clearly what used to appear blurred, by simply putting on Eye Balance, 
allowing you to clearly see the shapes and colors of things.
Dr. Nakagawa who is a Japanese author about many vision improvement books produced this item.
"EYE BALANCE" is an eye mask which lined small holes. This eye mask make use of the “pinhole effect” – allowing you to focus clearly without your regular glasses or contact lenses.
Relieve Eye Strain and Improve Your Vision.
