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.

Regarding the spectrum, you might be interested in these https://store.waveformlighting.com/collections/led-strips/pr...

kind of, kind of not. To the extent that brightness contracts your pupil, and the depth of field available to your eye increases with smaller pupil size[1]. People with focus issues find they can always focus when the light is bright enough (assuming normally functioning pupils). So there are optical properties that are affected by bright light, and your eyes respond to that. What the mechanism is for affecting overa…

Please do research on myopia progression. It's not unknown. This entire thread is full of people guessing at things they don't have any experience in.

A brief look at citations on Wikipedia seems to contradict everything you've said. Maybe you'd like to link some research?

Yeah I had the exact same response. There needs to be a 'permanently' in there somewhere.

"Through further clinical trials, it is trying to determine how long the effect lasts after the user wears the device, and how many days in total the user must wear the device to achieve a permanent correction for nearsightedness." Permanently wouldn't be very accurate either.

> how many days in total the user must wear the device to achieve a permanent correction

Sounds like they think it will be permanent, since they use the world permanent in that exact snippet you quoted.

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.

> My parents had corrective eye surgery in the last decade (corrected their myopia), and they claim the eye surgery damaged their "reading vision."

I'm -7.00 / -7.25 and this happens to me if I wear contacts instead of glasses. With glasses I can comfortably read a book or screen from about 10 inches away and beyond. With contacts I have to hold it at arms' length before I can make out small text. This is one of the many reasons I've stuck with glasses over the years. Another advantage of glasses is that I can take them off and have a natural and detailed "magnifying" effect. This comes in handy when soldering small components (wearing non-correcting safety glasses) or examining a circuit board for tiny defects like cold solder joints or broken components.

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…

There's hope that this won't be an issue in the future:

I've been following the development of this drug since before it was bought by Novartis.

I was expecting the average results to get better along with the median, but perhaps the dosage just wasn't high enough in this trial.

I noticed that when I started to measure the lightning in a room for home automation purposes.

It is really, really difficult to find the right spot that reflects "the light in the room" and then to find a threshold to switch on the lights "at the moment I would have done that".

I constantly hesitate between 30 and 100 lx, it is so dependent on the subjective light outside.

Glasses don't make it worse, per your optometrist. You just notice where you need to be. I'm about a -9, I wear contacts as much as possible; so I thought that's what you were saying. Don't be afraid to wear glasses.

My optometrist definitely said that I would not end up with worse vision overall, but that my vision would get worse faster. So per my optometrist, glasses do make it worse by my criteria (but not by hers).

Final outcome is identical. As noted below, your optometrists is mis-educated (https://www.health.harvard.edu/staying-healthy/will-wearing-...).

You will just figure out what your eyes really need faster by wearing eyeglasses.

That's the interesting part to me. I have very very very slight glasses. If I never put them on, it's fine. If I've been wearing them, and THEN take them off, everything looks horrible. I mostly only wear reading glasses at work.

Happens to me when I switch between contacts and glasses despite the same prescription (well, not that everything looks horrible, but that I notice how accustomed I am to the peculiar way glasses shape the world for a few hours). I wouldn't attribute too much to it.

You'll even notice it if you change the type of lens, to a higher or lower index.

Correlation does not imply causation but it does imply having something to do with the other. Your first sentence contradicts itself.

> Correlation does not imply causation but it does imply having something to do with the other Correlation does not imply having something to do with another. For example, in the first decade of the 21st century, spending on space exploration had a 99.8% correlation with a specific subset of suicides (hanging?).

"Correlation does not imply having something to do with another."

By its very definition, "correlation" means exactly "a mutual relation": https://www.dictionary.com/browse/correlation The example you're giving is called coincidence not correlation. There are times where words' etymologies loose their connection with their current meaning, but that is not the case here, where we have "con" meaning "together" + "relation", which is a logical construction agreeing with word's meaning.

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

I just bought weaker glasses online. There you can choose any values
