Gosh, feeling sorry for you. I have my own problems, but not that bad.
Over the years I have taken matters into my own hands and learned some things.
I have to figure out my own Rx because the eye dr cant. Do a lot of using additional *glasses* overtop of the Rx glasses (plus lenses over my minus Rx).
From what you said, not sure if you need plus lenses or minus ones (as for near-sighted).
But some suggestions in case you havent tried: I get plus lenses as from Walmart/Walgreens etc. more or less $$ as $6 -$12 and on up. You can try their various strengths in the store, to see.
Adlens is a brand, among others, that are available to purchase, no Rx necessary. I get online, but some stores carry — higher priced. Each eye lens can be adjusted separately within a limited range of + to -.
https://adlens.com/ They have had sales, and seem to be developing newer and newer models.
Let me know if you think I might be able to help you any more.
+ & - lenses, focal length is different in each eye. There is a fancy name for it I can’t spell. OD +200 -75 x 135 right eye, left OS +350 -50 x 060 was my April reading. June reading was worse in the left eye.
The glasses available OTC have no Astigmatism correction so are useless. I’ve found none higher than +250. Need +350 for the left eye. Astigmatism was caused by the cataract surgery. Never had it before hand. Never had glasses until I was 32 and needed just plain readers, went on to bifocals then trifocals, when that happened went to the progressive lenses and have been very pleased with them and even with some of the draw backs they have they work great. Time has seen a lot of improvement in them. I buy the best Zeiss.
Magnifying glass x 16 with led lights isn’t to far from hand when I need to read all that tiny font sizes on forms or boxes. Driving is limited to the grocery store. Good thing I’m married and have a built in driver, who has vision issues of his own, thanks to NAVY (20 yr career flight deck) cleaning chems putting holes in his vision Retinitis, and then developing age related glaucoma. He still sees better than I do.
The fact the left eye changes from 20/40-20/60 in a few days is the big factor now. It is not stable enough for a pair of glasses script. That machine can get me close, but does not fine tune, they have to go the old fashion way of mock glasses and keep changing out the lenses until I tell them what is best. Have another refraction scheduled for the 8th of Aug. Since vision in the left eye keeps wandering day to day, I don’t expect a script for glasses any time soon, but do expect a trip to Refraction Specialist and talking Lasix to fix the issue. Medicare/Tricare Life do not consider Lasix a needed surgery even for a medical condition.
