Ask yourself, how much brighter is it outside than inside (assuming a sunny day vs a brightly lit office)? Before looking into this, I would have guessed 2X or 3X, but would you believe it's actually over 100X! I bet most people's guess would also be off by 1 or 2 orders of magnitude. Even outdoors in the shade, it is over 50X brighter than indoors. (For specific numbers and comparisons, see: https://www.ncbi.nlm.nih…

Light perception is logarithmic, not linear, which is why your guess is so far off. 7 'shades' brighter and you're already hitting '100x'.

It is not actually "logarithmic" per se.

At a given level of adaptation the relation between luminance and perceived lightness is closer to a square root.

But over the course of about 30 minutes there are several different kinds of adaptations (some faster than that) which the eye/brain can make to the current light level, which has an effect of shifting that curve up or down by up to several orders of magnitude.

I've read this study a while ago, and I think it helped me correct my son's myopia. When my 5yo kid's eye check came back with "he'll need glasses next year", we started strict "hour+ outside play daily" policy. At his next checkup, he had normal vision. Dr was surprised.

I believe that's still under active research. If this is a factor, my money is more on "your eyes will be focusing more at infinity" rather then low light levels.

This, and I thus believe that a very bright VR pair of glasses that allows your eyes to focus on infinity would be superior to a monitor.

On a related note, I find it super interesting that people across many communities and forums report seeing eye sight improvements from daily use of VR headsets. Though it can take a while from those accounts I read, like average 1 hour a day for a year. In each case these people report not wearing glasses in the headset.

That's only correlation, light brightness has nothing to do with myopia. It's more likely from looking at things farther away from the face outside so that there is less light focused on the fovea.

You can only see that far away if the light energy is that abundant.

That's a pretty low amount of light, though. The sun doesn't even have to be above the horizon - Twilight, in different darknesses, exists. And you'll still be looking at things a bit further and the light isn't as concentrated.

The amount of detail sometimes varies, but then again, fog will do that especially when it is bright.

As are most human senses! Definitely hearing, vision, and smell; possibly also perception of force and weight, though the evidence is conflicting there.

Weight perception is very weird. The size of the object influences how heavy it feels. https://en.wikipedia.org/wiki/Size%E2%80%93weight_illusion

An anecdote for this: I got a heavy carbon steel pan for Christmas that I wished for. I didn’t expect it to be in the big box I got because it seemed to be too lightweight.

It's not just about whether you can see there's an oncoming car. For example, if you can't read the road signs ahead until a few seconds later than someone with "normal" vision, your driving will be seriously affected due to lack of timely information, and the added mental burden of trying to compensate for this.

My contacts are -1.75 with -0.75x148 astigmatism and I can't make out peoples faces unless I'm practically standing next to them. Nevermind trying to read a menu board at a restaurant counter or trying to find my glasses if I misplace them. Driving would be totally out of the question for me.

I wear glasses with similar lens as yours. I only realized I had myopia after starting to go to university, and I only realized I had astigmatism around 2 years later. I guess the brain learns to correct the image, at the expense of some headache if you depend too much on it.

More details from the Bloomberg PR: Kubota Glasses technology works to reduce the increase in axial length associated with myopia by projecting myopically-defocused virtual images generated using micro-LEDS on the peripheral visual field to actively stimulate the retina. Passive stimulation using myopic defocus is already in use in the US with a contact lens, “MiSight^® 1 day” by CooperVision, which is U.S. Food and…

Strip the jargon away and this sounds like it's saying "wear weaker glasses" and the device is just a fancy way to still see normally while having a weaker prescription in your periphery? Anecdotally, among a bunch of my friends who are (a) nearsighted, and (b) mad about sailing ships, spending a couple of weeks out at sea staring at the horizon will make a significant temporary difference to their myopia.

Re that anecdote, I was just wondering, do they stare at the horizon with glasses on or without?

Maybe some of you will find this beneficial if you have slight vision issues. It’s anecdotal, I don’t have scientific backing here. It worked for me, and I think it’s harmless to try. What I’m about to describe is what I think is the Active Focus method. I’ve always had perfect vision but my dominant eye degraded slightly over the years so I looked into how to bring it back to full. No one in family wears glasses or…

Endmyopia is real. It works, and I’m not a shill. I went from severe myopia to 20/20 vision; although you need to put the effort in (took me 2 years to get to 20/20, but improvements have been steady).

I genuinely believe that optometrists are either evil, or horribly misguided with hubris.

Reads like snake oil to me. I'd love to learn how this devices reshapes your eye lens when not worn. There are methods out there that people swear by, but I haven't seen a drop of evidence. I'd jump at the opportunity if it worked.

If this worked I would take a loan if that's what it took. Most likely snake oil. Even more so since they are calling it "smart", I'm surprised there's no blockchain. Extraordinary claims require extraordinary evidence. This thing can somehow physically reshape the eyes (or the cornea at least) permanently, with no surgery.

Physically reshaping the eye, isn't as crazy as it sounds.

Your eye shape/length isn't set, it can both shorten and lengthen in response to stimulus.

I am by no means claiming this device works, just that changing the shape of the eye is at least theoretically possible without surgery.

" Maturity and Homeostasis of Refractive State Although emmetropization is generally thought of as occurring during early development, homeostatic growth mechanisms need to be at least as precise during maturity if size is to be tightly maintained. Does vision guide eye growth only during a narrow period in development? In tree shrews, there is clear evidence of a period of maximum sensitivity to form deprivation (Siegwart and Norton, 1998). In chicks, however, it appears that susceptibility declines steadily from the earliest period, perhaps being related to the growth rate, with older animals showing consistent but smaller responses to form deprivation (Wallman et al., 1987), even up to 1 year of age (Papastergiou et al., 1998). Adolescent marmosets and rhesus macaques also show decreased, but still significant, form-deprivation myopia Smith et al. 1999, Troilo et al. 2000b. In humans as well, there is evidence of changes in ocular dimensions in young adults associated with the progression of myopia, perhaps related to visual tasks (McBrien and Adams, 1997). Thus, the young adult eye is still subject to visually guided growth."

You are talking about hyperopia (farsightedness), not myopia (nearsightedness) in your case, right?

I’m talking about nearsightedness. But in all honesty I don’t know what the underlying causes are as I haven’t been to an optometrist about it. I think my last check up was when I was in grade 6. Horrible, I know. I noticed it a few years ago and it bothered me enough to do some late night googling to see what snake oil I come across, but I decided to give it a try as a “I doubt I’ll permanently injure my eye trying…

I’ve tried it and it worked perfectly for me. I went from -4 and -3.5 to perfect 20/20 vision over 1.5 years.

Other than vision, the second big change to me is I no longer trust science as much as I used to.
