You’ll always fall for it if you are looking for an easier answer, for less personal accountability, if you’re unwilling to do the less-fun thing of reading a bit of science and biology and other tediously dry topics. That’s a lot of science talk, you say (even though we’re barely scratching the surface here).īut that’s the thing about various Internet droppings of unicorn poop. And while the seeming magic of suddenly better vision with pinhole glasses may leave you curious, once you realize the cause of that experience, you should question their effectiveness in helping to improve your eyesight. But does that change anything about your minus lens wear? Sure you can wear pinhole glasses, you can affect the circle of confusion (which could have so many meanings here!), increases depth of field, etc etc, as discussed above. Minus lenses cause progressive, lens-induced myopia, and pinhole glasses have exactly zero bearing on that whole interaction. Hyperopic defocus from minus lens, axial elongation = progressive myopia And that elongation is exactly what science talks about, when they talk about lens-induced, progressive myopia. Progressive myopia is very closely tied to hyperopic defocus, and the stimulus that defocus creates telling your eyeball to elongate. We’re going deeper here, because even mainstream lens-sellers won’t tell you about this (even though optometry science totally admits it). Those who sell you pinhole glasses to improve your eyesight, don’t understand (or don’t want you to understand) the actual cause of progressive myopia – which is stimulus created by the ever increasing minus lens “prescriptions” you wear. Pinhole Glasses Don’t Reverse Progressive Myopia But that’s confusing causality (you stopped staring at a screen, that’s what helped your vision – not the pinhole business), which you now know not to do.īut wait, there’s more. Or they can, if you wear pinhole glasses and go outside – instead of staring at a screen. Pinhole glasses don’t change the cause of pseudomyopia, the focusing muscle spasm. The best way to fix an issue effectively, is to address its cause. Referred to as pseudomyopia in most clinical science, this is what happens every day when you stare at a screen for hours on end. Your distance vision s tarts to be poor because of a ciliary (focusing muscle) spasm. Why does your distance vision suck to begin with?īecause you haven’t been wearing your pinhole glasses? No, of course not. Here’s strike one against the magical pinhole glasses: Pinhole Glasses Don’t Reduce Eye Strain Without a lasting trace.Īnd while you’re here and since there is more to this story, let’s quickly expand on this latter claim – exploring exactly why pinhole glasses won’t affect your vision once you take them off. Once you take off the tiny dots of glasses, their effect is gone. Pinhole mystery solved.Īlso: Pinhole glasses change optical properties – only while they are in place. Tiny dots, bigger depth of field, clearer image. Here’s a visual of the core premise of depth of field, the circle of confusion, and the underlying effect of pinhole glasses:ĭon’t pass out.
Simple optical concept once you understand it. In eyes with refractive error, the result is often a sharper image.
Similar to the workings of a pinhole camera, each perforation allows only a very narrow beam of light to enter the eye which reduces the size of the circle of confusionon the retina and increases depth of field.

Pinhole glasses, also known as stenopeic glasses, are eyeglasses with a series of pinhole-sized perforations filling an opaque sheet of plastic in place of each lens. Since if you don’t understand the optical principles of the pinhole magic, then you’ll easily be pooped on by this Internet unicorn.
To answer the question whether pinhole glasses can improve your eyesight, you first must understand how they work. Let’s dive right in, let’s understand the optical properties possibly magical glasses, and how they affect your eyesight: How Pinhole Glasses Work Well … do pinhole glasses improve eyesight? Variations of this question arrive on the doorstep of endmyopia frequently, lots of people apparently want to know if pinhole glasses can really improve your eyesight. Why do I suddenly see more clearly if I wear them ? What does that mean for my long term eyesight? Should I keep using them or are they just more Internet unicorn poop droppings?
