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 standad, so that the eyeballs are relieved
from the previous nervous focus. You can feel 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, aging from child to aged
people. When your eyes feel stressed, or during/after your work or reading,
just ware this like a normal glasses, and look to far away objects for 2 ~ 3
minutes.
