Pinhole Glasses

"Perfect vision in the unaided eye requires the eye lens to focus light rays from diverse angles into a single pinpoint directly on the retina at the back of the eye. For sufferers of refractive eye disorders, where the eye lens is too weak or the cornea or eyeball is misshapen, divergent light rays become focused in front of or behind the retina, casting an unfocused image onto the retina itself. This unfocused area of light is known as the 'blur circle'.

Pinhole glasses work by reducing the diversity of angles from which light rays can enter the eyes, allowing only direct light rays within a narrow angular path to strike the cornea. The lenses of pinhole glasses are perforated with an array of equally spaced minute holes of approx 1mm - 1.5mm in diameter. In contrast the average diameter of the pupil in normal daylight conditions is about 4mm. Each pinhole allows only direct rays through, and it is the amalgamation of these direct rays that make up a concentrated beam of light that enters the pupil. When this restricted light beam passes through the pupil and into the eye lens, the effects of any refractive eye disorders are reduced as the 'blur circle' on the retina is proportionally smaller. The resulting visual image is one of increased clarity, definition and brightness."

The truth about pinhole glasses

Have you ever tried this glasses? I tried once and I really have seen better with them.
Have you tried to wear a longer period? What is your opinion about these glasses?

[Epictetus]

You'd look like a chump wearing them; I can tell you that. NOT

[Asguard]

Why would these be better than stranded glasses which just correct the focal issues

I guess you mean 'standard' glasses?

LOL....

...now those ^ I could get into.

The pinhole occluder, a device used by ophthalmologists and optometrists for diagnosis of refractive errors, works on the same principles, but is not intended for use outside of diagnosis.

So this device is used only for diagnostics not for everyday wear. I sure wouldn't want to wear them.
