I've considered buying those glasses! I know you can buy them with or without prescription lenses. I'm 13 months out from my first bout with covid and I still can't go to the grocery store without feeling immediate fatigue, confusion, & incoordination. My physical therapist thinks it's the fluorescent lights and all the visual stimulation (looking up and down the shelves, turning corners to new aisles, watching out for people in the aisles, etc.)
My neurologist believes I have a migraine disorder, but I haven't had the opportunity to ask her about those special eyeglasses.
My optometrist said my prescription had changed a lot when I went to see him 6 mos post-covid. When he put letters in front of me, I couldn't read them. I told him the letters looked like heiroglyphics to me. I guess it was so much double vision or "ghosting" that was causing all the letters to be unrecognizable to me. I have a new pair of lenses, but I still struggle with whether to wear them or not wear them as I walk through the grocery store, down the hall at work, when looking at my PC monitors, TV, etc. It's like there's no perfect scenario. I can't figure out which is better: with or without my prescription eyeglasses.
Thanks to your post, I may reach out to my neurologist sooner rather than waiting until my next appt to ask about these special lenses. I need relief! It is just too much to try to walk through the store, find my items, then get up to the cashier and put my items on the checkout (the back and forth motion sets my vertigo off so bad!) By that time, I don't even want to keep my eyes open or look at anyone, much less operate the debit card machine. 🙁
The sensory overload you are experiencing may be due to brain stem inflammation. I have a Covid vaccine neurological injury, which resembles Long Covid. I'm a member of the Neuro V Long-Haulers Facebook group. A Danish physician who is helping us attributes the sensory overload symptoms you describe to brain stem inflammation. He recommends anti-inflammatory supplements such as palmitoylethanolamide (PEA).
