My optometrist told me that I have a tendency to 'overcompensate' the last time I had my rx checked; I now tell the optometrists that I have a tendency to overcompensate and ask that they dilate my eyes before anything starts and it's really helped me reduce eye strain.

#172The 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:…
What sort of prescription is right for Oculus?

#173Before I got my first pair of progressives lenses I saw a lot of conflicting anecdotal accounts. After doing research, the conclusion I came to was simple: I got the very best progressive lens that Lens Crafters sells because the best lens has a much larger intermediate “corridor” size than less expensive progressive lenses. I have had zero issues with my progressive lenses. I forget I even “have” progressive lenses…
I thought similarly and went with the most expensive lenses with the largest "corridor" for my first pair of progressives. They're great for up close and distance, but for me so far, the middle distance region for screens is a sham. There's almost no spot where the monitor is both clear and non-straining, and the tiniest shift of my head causes warping or blurring. I've had them redone but it didn't solve the fundamental problem.
Maybe my astigmatism correction is causing problems, though it's a small correction. Do you have any astigmatism in your prescription?

#174As someone who's been wearing glasses for all my life:
1. Your eyesight is not exactly "fixed". It can vary during the day depending on stress, tiredness, dryness, etc..
2. A prescription glass can help and does help but it doesn't magically fix your eye sight. If your eyes are strained from lengthy screen usage, the glasses are not going to do anything about that.
3. There is a possibility that your doctor prescribed you un-correct glasses. It took me a while to find my "correct" range.

#175Has anyone used the app http://www.glassesoff.com/ ?
I'd be interested and negative and positive experiences!

#177I'm nearsighted with no astigmatism, so I have a simple -2/-2 prescription (if I remember correctly). I sit at a screen 8-16 hours a day. I get strong headaches every single day, for which I keep a supply of ibuprofen at work and home. 400mg a day is generally plenty. I do not wear my glasses while at the screen, as it's close enough that I don't have any issues. I suspect my headaches are neck muscle related, not ey…
You're probably suffering rebound headaches at least most of the time.

#178In the hope that someone else has the same issue as I do and knows a solution - for me, my eyes, I have a double image. It moves. I have 12 pairs of glasses I've gotten from 3 "doctors" and several visits to places like Warby Parker, Jins, ZOff.
In all cases, all the doctor did was stick me in the machine, read off the numbers, give me some glasses. They work 10% of the time. I don't mean one in 10 doctors gave me good glasses. I mean on Tuesday pair #3 works. On Wednesday pair #7 worked at 10am but then stopped working pair #11 worked at 5pm. More often than not, no pairs work.
I feel like I need some kind of adjustable lenses (I'm imagining something steampunk with multiple lenses or a dial so I can dial in what works AT THIS MOMENT) but AFAICT no such thing exists
Does any one else have this issue?
Note: I have no pain
Anecdotes
(1) A doctor in SF put me in the machines, measured my eyes, made me some glasses. I come back a week later and using them is worse than not using them. I tell them they don't work. They get upset and reprimand me. Finally they give in. Make a new appointment. A week later doctor sees me, makes a new prescription, orders glasses, a week later the same, using them is worse then not.
Again they get angry an berate me. They give my some BS about I should take them home and let your eyes get used to them. I respond, if that's the case then the doctor could not make a prescription with his machine because I'd need to take the machine home to "let my eyes get used them" before he'd know if it was working.
Anyway, they finally let me make another appointment. the doctor measures and claims he knows what must have happened (didn't tell me) and orders another pair. A week later I check. These ones are marginally better than than not wearing anything AT THAT MOMENT. It take them home, every time I try to use them they're worse than not using them. (oh, and they apparently charged the eye insurance $999)
(2) My previous SF doctor I had a similar experience in that their glasses didn't work. They didn't berate me. They re-ordered once. I was shy and didn't complain the second time even though they were no good and I never used them.
(3) I've bought lots of glasses at Jins (Japan) - They have fully automated machines for measurement. I've got 2 pairs from them that help the most often, though not always.
(4) Last time I bought glasses I was at ZOff in Japan (because the wait for Jins was too long). The "doctor" their claimed my eyes were fairly good - meaning the images are clear, it's only the double vision that's the issue (letters look like there's a ghost 15% as bright/dark) about 4cm down from the actual letters)

> I also avoid […] high-index lenses for computer work. Yes! You're the first to mention this. It's not refractive index itself that's the problem, it's dispersion (roughly, the degree to which refractive index varies across the visual spectrum, described by ‘Abbe number’). We've all seen pictures of a prism splitting a beam of white light into a rainbow — for visual purposes, the less split the better. Higher-index…
Hear, hear!
Here's a good way to test your glass's refraction index. On your desktop find a small red icon with something white in the center. Stare directly at it. Now turn your head until the icon is at the edge of your vision. If your lenses are cheap polycarbonate, the white part of the icon will appear to move towards the edge of the icon or even out of it.
Most non-cheapo glasses today in the US use Trivex. It's a polymer, not glass, but its Abbe number is 43, which is perfectly adequate.
Crown glass, with its Abbe number of 59, is superior, but the eyeball can discern differences only up to 45-50, so most of Crown glass's improvement over Trivex is imperceptible.
This is partly why it's not offered in glasses (again, in the US, at least according to my optometrist). It is also twice as heavy, shatters (polymers like Trivex don't), and scratches more easily.

#180Castor oil drops on the eyes, and beard packs.. I guess they call them neck wraps for everyone else.
Also xylitol and salt sinus flushes help, even with those floaters.
