When I was young, every time I got a 20-20 prescription, my eyes got worse. When I stopped going to the optometrist, my eyes stopped getting worse. Now I wear glasses that only correct to around 20-40. I take them off for reading, and I have weaker glasses for the computer screen. Supposedly I have astigmatism but I use no astigmatism correction and can see fine.

I don’t know what your intentions or hypothesis are, but this is a dangerous place to be a novice in. Eye health is misunderstood and most people are ignorant of the basics. If you don’t know what emmetropization is, if you don’t know who Bates is, and if you don’t know why Bates is a quack, then I strongly discourage you from experimenting with user surveys.

I mean, what are the risks of the surveys? I don't think it will be dangerous to survey people without the full knowledge. Better to be curious about it than do nothing. Discouraging low risk research just for being pendantic sounds a like toxic gatekeeping.

I don't really know if anybody will read this, but if somebody does and knows what it is, please give me some advice. I see double text, not anything else, only sources of light, like anything on a computer screen. It is like what I am seeing from both of my eyes does not line up correctly. On a completely white background, I see spotches of grey. I have visited two or three doctors and each gave a different prescrip…

I have keratoconus and stigmatism. 8 years ago I stopped wearing glasses since my vision was good enough for laptop, phone and watch but distance was always a problem. I've been doing eye exercises daily for 8 years and my 3D vision returned last year and on more and more days I can read the street signs across the street, as street signs in the US. My prescriptions used to vary between -3.25 and -4.25 with 90% distortion. My laptop vision is better also. Lately, the glare that emanates from the source of light is less and reflections off of glassy surfaces are also less. My first diagnosis was 35 years ago and over the years various surgeries and fixes were offered. Over the years, technology improves, so I feel I wait. Prognosis so far is manageable. Best of luck to you.

The solution for me to eliminate headaches when working at computer screens was getting an extra set of intermediate distance glasses specifically for computer work. The "computer screen distance" of 3 ft is in between book-reading distance of 1 feet and driving distance 20'+ feet. I also avoid progressive lenses or high-index lenses for computer work. I commented about how arrived at this solution previously: https:…

I only need a basic 1.0 reading prescription but I have about 5 pairs of glasses. I'm hyper-sensitive to even the slightest deviation in prescription. Currently wearing, to look at arms-length monitor screen, add +1.0. Will move out to the porch to read and switch to add +1.5. Will come back to cook and switch to my basic prescription. I must put on and take off 300 pairs of glasses a day. But I don't care. I can't d…

I’d love to speak with you - your experience is right in my target zone to research. If interested ping me at jbornhorst [at] gmail.com

Earlier quoted context omitted.

Shit, It did match, looking at the text through the edge of a card does make it clear for me. Although the blurriness is not as extreme as given in the wiki page.

https://www.reddit.com/r/Keratoconus/ -- but do not freak out, most cases are completely treatable with scleral contact lenses, social media bubbles up the outliers. Next step is ophthalmologist, ask for a corneal topography (photograph and measure the surface shape of your eye w/ a computer) to establish a baseline and monitor for progression. Not all ophthalmologist offices have the corneal topography machine so as…

I was recently diagnosed with keratoconus, I'm 28.

I'm unable to get CXL for at least a year due to demand.

What sucks the most about the diagnosis is that the opthalmologist explained that there's essentially no treatment, it's progression can only be slowed, and I'll never be able to get LASIK or SMILE.

I went decades thinking that all prescriptions were imperfect until I started getting age-related presbyopia (reduced close focus abilities) and sought perfect correction or a clear reason that it couldn't happen.

The diagnosis: keratoconus (thinning and ultimately misshapen cornea). The prescription: highly-corrected rigid scleral contact lenses. The result: radical. I would describe my uncorrected vision as 480p, glasses as 1080p, and scleral contacts as 4k.

The scleral prescription makes my medium and far vision great while further limiting my ability to focus closely. I experimented with "monovision" to have one near-focused eye and one far-focused eye with my brain sorting out the difference, but I could tell that it resulted in lower resolution. I optimize by sticking with the medium-far prescription and wearing 1.5x reading glasses for anything within a few feet. It works great.

If you're in a similar boat, I can't recommend it enough to get checked for keratoconus. To get that you'll want to find a place that can do a corneal tomographic scan with a device like a Pentacam. Oh, and try to not rub your eyes and tell your kids the same because it's believed to be a major cause. I used to do it for fun as a kid to make colors while I was bored.

My ophthalmologist made the point that blurry eyes after lots of computer time is commonly from dry eyes, not blinking enough, and recommended TheraTears.

I found eye drops using trehalose to be significantly nicer, feel a lot better for my eyes. I know ivizia and thea thealoz use it. TheraTears were decent, but not as nice

My eyes have always bugged me, but I've also had allergies. It's also become clear over time that I have pretty bad astigmatism. I've always been farsighted. I first got "dimestore readers" specifically for computer use, to reduce eyestrain. When I put them on at the beginning of the day I'd notice some weirdness (phantom artifacts and double vision) but my brain would cancel it out and all was good. After about a de…

They won't officially try and correct to that level. I did maintain 20/15 both before and after, but still have a mild astigmatism, so I still wear glasses
