Anyone uses pinhole glasses (or stenopeic glasses)? I think you call so it in English, it's for gymnastics eye and for the Bates Method. They say that help reduce dependence on prescription lenses and the tensions caused by the difficulty of vision.
Do you have any experience? They don't hurt or damage the eyes?
And about the method Bates what do you think?
and the laser operation is too expensive and I'm afraid of going blind
