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…

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 was in the "slowing going nearsighted and avoiding glasses" phase for quite some time and the result was regular "ice-pick" headaches and migraines. Getting glasses fully cured all of that. My prescription also hasn't changed in 10 years, so (for me, at least) glasses have only had a beneficial effect.

I've been nearsighted my entire life and do not wear glasses. I get the headaches after a couple of hours of wearing them. More than likely it's more to do with what you're accustomed with than how good your vision is.

Get some contacts!

I have a lot of questions, but I'd definitely pay if it worked. I've very slowly been getting more nearsighted, but I mainly avoid wearing glasses. My optometrist said that wearing glasses would speed the slide, although I'd eventually end up at the same level of myopia. I'd much rather wear glasses that fix the problem than make it worse.

High recommend contacts if you aren’t sure about glasses

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…

I summarized the EndMyopia/Todd Becker stuff at losetheglasses.org if anyone wants a short, readable version. The method continues to work for me, albeit slowly.

Excellent summary. Thank you for this.

One thing I forgot to mention is that when I started, I didn’t even have actual blurriness for the most part (unless it’s really far away). I had double vision along the vertical axis, and I did what Becker recommended to do which is to try to focus on the actual object (in my case mostly text), and ignore the ghosted copy so that two of them can converge. I would then intentionally defocus by looking in front or behind the text, and then try to refocus again. It keeps it slightly interesting/amusing.

There’s way more stuff out there on this topic today then there was when I first started practicing it, but it doesn’t seem to have changed all that much. People are still very skeptical about it and I guess optometrists still don’t talk about it.

ok I've always wanted to map it out and keep track of them, I swear they come and go, so going to try this out later! If you can shed more details that'd be awesome! Does the droplet have to be dead centre??

The droplet doesn't have to be dead centre. Basically you stare past the droplet and see the glint of light in it as a big blurry orb of light. That's the "spotlight", basically.. That's it. If you squint your eyes, and see relatively sharp shadows of your eyelashes impinging on the orb, it's working.

Heh... my myopia is so severe that I get the effect just by taking off my glasses and looking at a point light source.

Christmas trees look like psychedelic, technicolor schools of puffer fish, and I can clearly watch the intra-ocular "weather" as I move my head/eyes around.

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

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

Don't forget sound perception, which is one big reason we measure loudness in decibels.

It's probably based on the theory that over a longer time frame the eye adapts to slightly defocused images in order to bring them in focus. The key is that the image must be defocused only slightly, not grossly.

So wear slightly weaker glasses? Yep.

I don't think this has been conclusively demonstrated yet.

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
