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…

When I tried to inject fake daylight into my basement office, I realised just how "special" daylight is. It comes in from everywhere. Flood fills with so much light as such a broad spectrum.

When last I looked, there were some very expensively priced daylight lights - complete with blue sky. CoeLux has a scattered light indoor skylight.

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.

> My optometrist said that wearing glasses would speed the slide This is a myth widespread among opticians and optometrists. I have discussed it with those who treated me and not a single one could provide any evidence.

On several occasions I’ve been the the optician and found my eyesight had gotten better. For me, at least, this myth is evidently false.

There's something called SMILE if you're interested in surgery. I recently had it done.

can you tell me a bit more about costs, any side effects, and whether you are satisifed?

Ugh. I had fairly stable myopia and was content. Recently developed astigmatism in my strong eye and so my overall vision is substantially worse. Anyone know what can cause sudden onset of astigmatism in adulthood? It appeared a couple years ago and seems stable. Not sure over what period it appeared, probably in 3-12 months.

I always thought it was genetics or perhaps excessive screen time is my next guess but I've been told its not possible.

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.

Focusing on infinity more has been tested using glasses designed to force this, it was a popular theory for 60 years or so, and many opticians prescribed glasses which forced people to do this as a result. I cant find it atm, but the result according to a large metastudy was that it caused headaches, and nothing else of note.

Wow in what country do you live in? I have NEVER in my live even have an optician hint at that. The best I got so far was slow understanding of why I am ordering glasses to focus the screen at infinity (one out of 10). All others stare blankly at me and say like "Uh that's illegal, we can give out glasses that potentially ruin your eyes". Well I kept thinking, "Yeah, that's just what you are doing all day" :D

Has anyone here given this a try: https://gettingstronger.org/2010/07/improve-eyesight-and-thr... https://gettingstronger.org/2014/08/myopia-a-modern-yet-reve... It claims that myopia can be cured, just like muscles can be made stronger in a gym.

Anecdote: I used to get new glasses/prescriptions every year. Every year my prescriptions would get stronger. Last couple of years I stopped renewing my glasses and whenever I absolutely need to get new glasses, I have the store use my old prescription. For whatever reason, my eye sight stopped getting worse. I think by wearing stronger prescriptions, your eyes adapt to it and you get more and more myopic.

Me too.

And to everyone saying "its just age"... well, it doesn't seem that way.

I noticed this pattern and stopped going to the Optometrist for five years. When I finally went again, my myopia was -0.25 worse, so I got new glasses. Then I went again the next year and its -0.25 worse again.

My myopia didn't worsen over a period of five years. Then suddenly worsened over a period of one year.

You might be interested in this video too. There’s more to it than just the color, sunlight’s rays are (virtually) parallel, because the light source is so far away. https://youtu.be/6bqBsHSwPgw

-2 is not that blurry. You may not be able to reliably read a license plate at distance but you'll still see the (mildly blurry) car coming at you.

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.

I'm struggling to think of a road sign that isn't either placed well in advance of when you need it, or something like a stop sign where blurriness doesn't matter.

Just street names, I guess? Those are a pain to navigate by anyway. You often already want to be in a lane by the time you can read the sign. The proper the way to relieve that mental burden is to have a navigator or GPS.

My understanding of the parent's post was that someone with -2 vision may expect roughly perfect vision as their eyes age. I couldn't find a study with data, but there are anecdotal guides online (for picking reading glasses) which state that by 60 years old, it's estimated that a person would need about +2.25 diopters in correction. So someone who is around -2 diopters may expect to have roughly perfect vision as th…

This is a misunderstanding of what happens to your eyes as you age. Your eyes lose the ability to change focus. People with normal vision will have their focus stuck near infinity and will need reading glasses for close up things. People with mild myopia will have their focus stuck at close range and therefore won't need reading glasses. They will still need glasses to see clearly far away, but they always did, so it…

My parents had corrective eye surgery in the last decade (corrected their myopia), and they claim the eye surgery damaged their "reading vision." They lament the loss of their reading vision, and I have to keep explaining that they're experiencing presbyopia and not some damage the surgery caused.

My myopia is pretty bad (-9.25 and -8.5 in contacts), so I don't even get the benefit of reading without correction.

Neat. My prescription changes every couple of minutes. But along a predictable curve. I keep thinking about getting optometrist adjustable lenses hooking it up to motors to automatically shift the lenses. Mechanical is beyond me though.

I haven't heard about this, could you elaborate?
