Anyway, I took a look at the sight (pun intended); was instantly beskepticled (ibid) and told them that I'd need a pair to check out and would not promise a positive review. One small thing gave me hope and pause.
Please Note: Pinhole glasses are meant to be used only for stationary viewing. It is dangerous to use them when you are moving as it affects peripheral vision of the eyes.
I wrote large parts of this review while wearing them. I'm extremely astigmatic and have artificial fixed focus lenses in my eyes after developing cataracts. Well, these do actually correct my astigmatism, and I can see the downside to moving your head - your vision blurs suddenly. I found that my brain compensated very quickly, both for the oddly spotty (literally) vision (referred to on the site as "the honeycomb effect") and the drastic reduction in the total amount of light. (Not a downside here in Nevada, I should add.)
I've never really had peripheral vision that I can recall until I did get my new lenses installed. I used to be so extremely near-sighted that the world was a blur without my coke bottles, and my brain is used to relying on peripheral vision for motion detection alone. Your mileage may vary on this point, but AS a point, it could be easily addressed by making a wraparound style.
I think it may also enhance the brain's ability to detect motion - I think it would be a great idea to get some data on this; if so, these might be of use in sport protection goggles.
I did try wearing them over my bifocals and found that suddenly my entire field of vision was available with full sharpness - indeed, sharper (if dimmer) than my corrected vision alone, and without the annoying search for a "sweet spot." It's very difficult to tell exactly, how well it would work with the pinhole layer actually integrated with a prescription lens - but my intuition and crude experimentation says that it's well worth finding out.
From the site:
Pinhole Glasses are special tools In Pinhole glasses, holes of 1-1.5mm are spaced regularly using laser technology.
Yeah, that would probably be better. These pinholes are molded sheet plastic and I suspect that it's a stock sheet that is not really designed for the task. Nonetheless, it certainly does work. And the fact that the holes are actually conical in cross section may be a feature. It may not be. More data is required, and I've no way to go further along these lines.
They may not be suitable for use in some instances.
Wearing pinholes affect your peripheral vision. They should not be used when you are driving or while moving about. It reduces the amount of light entering your eyes. Therefore, it cannot be used in environments having dim light. Wearing pinhole glasses does not prevent harmful UV rays from entering the eyes. So, do not use them to view the sun. It is also not useful for people measured as requiring lens of more than 6 diopters. Other eye problems like diffraction will prevent them from experiencing any significant benefits upon wearing pinholes.
It is always advisable for young people to avoid using any visual aid. Working on their eye muscles can improve their vision considerably.
As I said, the entire site comes across as a scam; this is not aided by their promotion of expensive "acupressure goggles."
As it happens, I'm not at all skeptical about acupressure; what I am skeptical about is the ability to automate an intuitive art, and extraordinary claims require extraordinary evidence.
To say that the links to supporting science for these products is sketchy is charitable. But leaving the accupressure goggles aside completely, there is a great deal of science, history and experience behind the use of pinhole lenses and the application of some real optical science to the matter would result in a better site and a far, far better product.
Guys; Go thou forth and find ye an optician and an optical physicist!
Meanwhile a set of these plus a workbook on the optical effect is well worth marketing to science classes - with various editions for college, middle schools and lower grades. It's possible to directly observe the physical principles at work far more clearly than by other means.
I'd suggest connecting with education writers and publishers. That could nicely fund further R&D - or indeed, produce the same results for free from fascinated bespectacled minds.
Does the plastic have to be opaque? Because if the plastic were sun-glass lenses, that would definitely improve the experience.
Would a thin film with ideal sized holes (laser drilled, perhaps) work if applied to ordinary clear or tinted lenses? Could the film be printed instead of drilled?
And would it make sense to consider creating pinhole/slit arrays specifically for individuals?
The advantage would be that you might be able to literally PRINT lenses, or use any number of inexpensive Computer Aided Machining tools to produce something that would work well enough at a very, very low cost per unit - and this could make a huge difference in the third world. Heck, it would be pretty darn cool right here. But this needs to be stated strongly: What exists right now is good enough to make a huge difference in the third world.
