Are Modern Pinhole Glasses Right for You?

Pinhole glasses otherwise known as stenopeic glasses (Greek for ‘little opening) are composed of standard plastic or metal frames with inset perforated plastic lenses. The concept behind pinhole glasses, the “pinhole effect”, has been around for centuries though it may seem to just be coming to some level of prominence. Optometrists who are qualified to examine vision use pinhole glasses as a sight aide for patients who can no longer benefit from the use of conventional glasses. These include patients whose vision is affected by a scarred cornea. Pinhole glasses are best used for the elderly, computer users and those who suffer from refractive eye disorders. The pin holes are formed with the use of laser technology to gain accuracy.

Modern Pinhole Glasses and How They Work

Located to the back of the eyeball is the light sensitive retina which is a layer of tissue that acts like a film. For people who have a perfect eyesight the rays of light that enter the eye and focus on a particular point of the retina. For those who suffer from a refractive disorder, light rays that enter the eye are focused in front the retina or behind it, depending on the type of disorder. The misdirected light cast a ‘blur circle’ to form on the retina. The retina actually acts like the lens of the camera as it captures the images from the lens, converts them and then send an electric signals to the brain about the image. As you can imagine, if the image falls in front of or behind the retina there is a problem.

The plastic lenses of pinhole glasses carry minute holes on their surface that cause the hole in the eye through which light travels (the aperture of the pupil) to adjust. When this happens a narrower beam of light is allowed to pass through to the lens. The blur circle that is cast unto the retina is smaller than that which would form without the use of the glasses. This improves your vision as the glasses blocks out the peripheral rays and only allows the rays that pass through the central area of the pupil to enter the eye.

The continued use of the pinhole glasses for just 15 to 20 minutes every day for a few weeks along with certain eye exercises can help the eye to heal. When the ciliary muscles are too weak to pull the lens into the correct shape or the patient’s cornea or eyeball is misshapen they naturally squint to block out the light coming from diverse angles. This is the eyes natural reaction to correcting the problem, but with the aide of the pinhole glasses this can be achieved much faster and much more effectively.

Eye professionals are now widely embracing the use of pinhole glasses to help their patients gain far more improved eyesight naturally. Many readily agree that in the long term, prescription glasses only cause the problem to worsen while pinhole glasses actually offers a natural alternative that trains the eye to function as it should.

Pinhole glasses are now seen as the perfect option for curing eye problems in not only adults but children as well. Whereas in was once used only for patients with extreme problems, the glasses will be used to treat a range of conditions such as myopia, presbyopia, hyperopia, computer vision syndrome, cataracts and astigmatism.
