Pinhole Glasses
Pinhole glasses are used by people to assist them with a variety of vision problems. They are also called stenopeic glasses, and as both names imply they work by blocking excess light and focusing the light that is allowed into the eye. Pinhole and stenopeic both refer to the small openings in the lenses. The reason for this is to block out the outer rays of light and concentrate on the center rays. The goal is to reduce the refractive errors in the lense that account for some common vision problems. Doctors use this kind of lense in testing eyes to see what level of sight can be achieved when the refractive errors in the lense are corrected by prescription glasses.
Some of the vision problems that are said to be helped by pinhole glasses are : myopia (nearsightedness), hyperopia (farsightedness), presbyopia, astigmatism, and computer vision syndrome. These glasses are not intended for driving and should not be used at those times. People have reported that they are helpful in reading, when dimestore readers are not enough and prescription glasses are too expensive. Also, it has been reported that pinhole glasses are helpful for those who do computer work in brightly lit offices. They are said to reduce fatigue and eyestrain in this work.
Pinhole glasses are not for everyone. It is possible that certain eye conditions are too severe to be helped and many doctors are reluctant to actually endorse them. However, there are many, many years of anecdotal evidence and user testimonies. Some people feel that their vision has even been improved by using these lenses.Some people claim that they are helpful in delaying the need for cataract surgery and it is also suggested that they can slow the progresion of myopia. While all claims have not been proven at this point, certainly there is enough user information to help you decide to try pinhole glasses for yourself.
