What Are Pinhole Glasses?

Pinhole glasses, also called stenopeic glasses, are plastic eyewear with hundreds of pinhole-sized perforations in place of lenses. Pinhole glasses are mostly used to improve refractive errors in the eye because they shield the eye from indirect rays of light which can distort vision. This would decrease the blur circle on the back of the retina.

What Do Pinhole Glasses Do?

Pinhole glasses are often used by eye doctors who use them as a diagnostic tool to quickly check for vision impairments. Of course, pinhole glasses are sometimes used to treat nearsightedness or astigmatism. Pinhole glasses are also used in conjunction with an occluder, an instrument used to cover one of your eyes while you read an eye chart. The occluder is solid, while the pinhole glasses have a number of tiny pinholes. So, the doctor often uses it to check the potential of your vision.

Pinhole glasses are often used to check corneal distortion and cataracts. A cataract evaluation includes focusing light in the eye to check if vision capability behind the cataract makes it worth performing surgery.

How Do Pinhole Glasses Work?

Compared to traditional glasses, pinhole glasses work differently. Traditional glasses correct your vision often by collecting rays of light as they enter the eye and forcing them to converge on the retina rather than behind or in front of it.

However, pinhole glasses limit the amount of light entering your eyes so as to enable people to see more clearly.

Can Pinhole Glasses Improve Your Vision?

The most important question may be whether the pinhole glasses improve your eyesight and some people may have this trouble. Some people say pinhole glasses can improve the vision of nearsightedness or astigmatism. But there is no evidence to prove that.

Although pinhole glasses can improve vision to some extent, they are not practical for everyday use. Pinhole glasses are designed to block part of your direct vision and restrict peripheral vision. They would cut the amount of light entering your eyes so as to reduce the visual quality of an image. Hence, it would be not recommended to wear pinhole glasses in daily life.
