Pinhole Glasses? Do they work?

actually its an eye exerciser if you know how to use it.on the first day of using it, don't wear it more than 10min but you can repeat it only after at least 30min. then on the 2nd day add 5min on wearing with the same rest period. until you can wear it for 30min a day then improvement will come. wearing eyeglasses is like wearing magnifying glass that will make eyes go tired and this is the reason why people upgrade most of the time their eyeglass. while wearing eye exerciser, exercise the weak muscle of the eyes, so following the method will refresh your eyeballs and you will feel it until your eyesight will return to 20/20 vision
