If I do not have dark sunglasses - sunny or cloudy - I am in extreme pain, if not completely unable to open my eyes. I almost did not pass my initial scuba certification because every time we surfaced I was blinded. I have wondered if I can get a prescription mask that acts like those sunglasses they make, that darken when exposed to light. That would make my life so much easier. I'll wear sunglasses before the sun is completely risen, and after it has set. If there is any light in the sky (other than stars), I need my sunglasses. I have even worn them sometimes at night while driving in traffic because the headlights - especially those stupid LED blue/white headlights - hurt like hell. Stoplights hurt my eyes day or night, and neon is a pain. The only thing that does not bother me - in fact I rather like, and find soothing - are red/blue police lights. Love those. I think it has something to do with the rythmic flashing, and the little clicky noise that they make. Does not hurt at all, either.
Not only do I need them physically, I have come to use them as a "shield" against people. I just feel safer with them on. People cannot force me into eye contact, and I can observe whatever I want unobtrusively. Sunglasses make my life SO much easier - I have pairs everywhere, just in case (learned my lesson the hard way after being blinded at the beach, when I lost them in a wave.) In my beach bag, in my scuba bag, in my car, in my purse, at the stable, at home, in drawers......everywhere, sunglasses lol
Noises bother me sometimes - I have been told I'm annoying to watch movies with because I find some parts of movies louder than others, and if allowed control of the remote, will constantly be turning the volume up and down as fits my comfort level. If I can't control the volume, I'll cover my ears on and off as needed.
One thing that realllllly drives me nuts - and hurts - is that TDD squeal/squelch sound for the hearing impaired. That sound makes me feel like I'm going to start bleeding from the eyes and ears.
