Pinhole Glasses - Regular or Exceptional

By: Mike Lamb

Pinhole glasses are regular glasses except for one small part: the part were you see through, which is covered by a series of pinhole fixed perforations filling a plastic sheet where normally the lens would be. Almost the same way a pinhole camera would work.
How It Works
Each pinhole allows only a narrow stream of light to enter the eye which brings down the size of the retina and increases the depth of field. If you have an eye sight with refractive image errors much like ghost images that makes it hard to see people, using pinhole glasses will give you a clear image, while prescription glasses will give you a distorted effect around the edges often called a "pincushion distortion", where an image is magnified at a distance making the images look like they are bent inward. Pinhole glasses are useful to anyone with nearsightedness or farsightedness. Pinhole glasses also reduce the brightness which affects your vision that happen outside of your gaze like peripheral vision. So it makes for a really bad idea if you want to drive or do anything that involves heavy machinery.
Marketing claims
A lot of marketers have claimed they can improve your eye sight with exercises but no scientific evidence have been found to support that. In the United States you can not make these claims because of the terms in the Federal Trade Commission which basically say you need proof your product can do what you said it can do for the market. Other than that it's not illegal to sell; you just can't make claims that it will do something it has not been proven to do.
Safety
If you want to wear pinhole glasses, remember they are not for driving nor any operating heavy machinery. When using your outer vision or your side vision is limited, it is a bad idea to wear pinhole glasses during any sporting activities or other activities involving the use of a whole field of view.
Looks
Pinhole glasses come in many looks some even with a glass cover so people looking at you won't know your wearing then. Making it easy to wear while working or outside of the house without people asking questions.
