Is anyone familiar with eye minus? I once went to two different optometrists, and ended up with completely different prescriptions, and only the one that realized I had a "minus" eye was the one that gave me the best prescription.
Easing Eye Strain with the Right Lenses (2012)

Re: Easing Eye Strain with the Right Lenses (2012)
#92I got a little pushback (not a lot) from my optometrist when I first requested an FD set at laptop distance. However it has made a huge quality of life difference for me. I also gave up on progressives and now have two pairs: readers and drivers. My current correction is insanely good for reading and for driving. In fact, my opto said it was quite a bit better than 20/20 with no eye strain. Well, there was some eye s…
FD = Fixation disparity (whatever that is...)

I was testing point and shoot cameras the other day and one of the things that impressed me is just how quickly and smoothly they can auto-focus. I found myself looking around at the world through the viewfinder screen and it occurred to me that with 400+ ppi LCD displays why have we not yet created a 'visor' which is simply a reproduction of the scene outside but in constant focus for our eyes (I wear progressive le…
The highest-density current VR headsets (at 4K per eye) still have a semi-noticeable 'screen door' effect from the individual pixels.
You don't need to include a pixel display for autofocus. DSLRs show the real world projected directly onto a screen at a comfortable focus distance for example.

Another anecdote for you: do a mental check you shoulder and back muscles. I’ve personally found (as have others) that my tinnitus intensity is closely tied to how tense my shoulders and upper back muscles are.
Thanks. That's in fact my third symptom. Really bad issues with my left shoulder in rare cases causing ocular migraines. Doctors claim it bears no relation, but I am sure it does. How did you fix yours?
By focusing on the muscle tenseness. Meditation, massage, hot water. And sometimes just some ibuprofen to break the "it hurts, so tense up, which causes it to hurt" cycle.
They're not perfect, but I'm mindful of the state of those muscles now, and can typically head off (or deal with) the tenseness.

Check out hybrid contacts. I had similar issues with my astigmatism. The contacts have hard centers and soft outer rims. As a result they can provide decent astigmatism correction/stability while being __much__ more comfortable than hard lenses. The things drastically improved my quality of life.
I too have an issue with soft contact lenses not providing great vision due to astigmatism. I tried getting sclerals fitted but had to return them due to the optometrist having trouble fitting them. The vision was crystal clear though -- shame it didn't work out. The downside was that they felt incredibly fragile and were quite expensive at around 1000$ for a pair. I pay about 300$ a year for daily soft lenses so tha…
I've worn both RGPs and hybrids.
RGPs are unwearable for me because of comfort levels. Even after a two week adjustment period.
Hybrids have been really comfortable for me. The lens change may take a day or two to adjust, but I tend to forget about them until ~14hrs when they start to feel a bit dry.
*Disclaimer there is variance among both eyes and lens manufactures (I've had some manufactures that felt dry really soon, others are much better).

This link says there are two numbering systems for cylinders that mean the same thing: http://www.usaeyes.org/lasik/faq/read-eyeglasses-contacts-pr...
Mixing up a Minus (near-sighted) vs Plus (far-sighted) value for sphere would be unusual.

I have anisometropia even more extreme than yours. I wonder, have you ever tried contacts? For anisometropia, the closer the prescription is to the eyes, the better. I choose to wear glasses now, but I still have to go out of my way to find small enough frames (unfortunately out of fashion) that the lenses sit close enough to my eyes that the images converge.
I didn't know that, but I have considered contacts for cosmetic reasons. However, they seem like an awful lot of hassle compared to glasses. Another question: wouldn't the contacts have to be complex/progressive lenses of some kind? Clearly, I need two different prescriptions—one for computer work, one for everything else. Does staring out a bottom or top portion of a contact lens pose any difficulty beyond what one…
I'm not an optometrist, and I haven't worn contacts in years. All I can tell you is that they weren't nearly as much of a hassle as people make them out to be. I just have strong, but not vision related, reasons to prefer glasses.
