There is a lot of things that drives me mad, but I'm not listing them all. lol
Now Tis, my problem is similar to yours, but as I got older I had to have Bi-Focals, having Dystonia does not help matters in my condition. It's like the Optician said "Having contact lenses are out the question!" as well.
I'm not sure if you seen what Dystonia actually does when it's Generalized, but believe it is very difficult to live with, ("come to think of it, my wife sometimes says that about me!"
) Every pair of spectacles I was forever breaking, I would pop the screws out then the lenses would fall out. I had spare glasses but they were put together with my own DIY, longer screws - but they used to stab me in the eye lids if they slipped.
The pair I got now seem indestructible, I told the optician about all the problems I have with wearing spectacles, like screws popping out, lenses falling, because I am heavy handed. He took all my problems in to account, and come up with a really nice pair that I've had for over 18 months now, and I am pleased with them. I can't pop the screws out he put a small amount of Super-Glue on the ends of the screws so they cannot come out, and these frames are super bendy. Now, you're thinking why would I want bendy frames! SImple I keep falling asleep with them on - I have found them in so many places in the bed, some have been uncomfortable!

My wife on the other hand has a very different problem with hers!! LOL She bought a really nice pair of spectacles, interchanging frames, etc. A few days later she come in the room without her glasses om, I said "OMG, what have you done around your eyes?" she said "Nothing, why?" - I said "You better look in a mirror, you like Harry Potter, gone wrong!" all I heard was "WTH, how did that happen?" - she phoned the optician and he said you must have a problem wearing anything metal. She had her frames changed to plastic! LOL - After that we thought about it, neither of us wear wedding rings, even though we are married. She stopped wearing hers because of the metal irritates her skin. Mine I don't waer because I kept catching mine and it kept cutting my finger in the same place.
Always fun in our house! in stupid ways!
Regards,
Les.
