Pinhole glasses are also known as stenopeic glasses. Essentially, they're eyeglasses with multiple pinhole perforations on each lens, and instead of glass, the lenses are made of dark plastic. Pinhole glasses allow only a very narrow beam of light to enter the eye, which then increases a person's depth of field vision and reduces the retina's blur circle.
Eskimos have been known to use pinholes to help cope with eyesight problems. They had to deal with the glare of sunlight, and so they made wooden spectacles with holes or slits to combat the problem.
Pinhole technology has been used by doctors to correct vision problems. This method is employed by Ophthalmologists to detect vision problems and prescribe eye glasses to people. It is believed that if a person having vision problem is able to view an object through the pinhole more clearly as compared to without the pinhole, then the person will benefit from the use of eye glasses.
Over the years, the outward appearance of pinhole glasses has shifted to reflect a more modern look. Current pinhole glasses are nearly identical to a pair of typical sunglasses, which has resulted in a more confident use of the glasses in public. The pinhole pattern is printed on the back of the lens, with a clear plastic lens on the front to provide UV protection. However, since pinhole glasses reduce the amount of one's peripheral vision, it is recommended that they be used only when sitting or standing still.
Pinhole eyeglasses are gaining popularity as more knowledge is gained about them. There have been many claims about these glasses and how they help to improve eye sight and cure vision problems. These glasses have minute holes at regular spaces made with laser technology.
But there are certain instances when these glasses should not be used. Pinhole glasses can affect the peripheral vision of the person wearing them, and so they should not be used while driving. Moreover, since the technology reduces the amount of light entering a person's eye, so it is not suitable for use in dark or dimly lit places.
Many people having vision problems like Myopia, Presbyopia, Cataracts, etc have started using pinhole glasses as they have tested this principle and have the faith and belief in these glasses. Pinhole glasses are gaining in popularity as more and more people are getting aware of their benefits.
Mike has been writing and publishing articles about health products. He recently came across a website on pinhole glasses which gave information about this old technique of using pinhole glasses for eyesight correction. Here's an article about pinhole glasses.
