Enchroma Grayson indoor color blind glasses

I am selling a pair of enchroma color blind glasses. They’re Grayson which is compatible with red/green color blind. I tried them a few times but they felt too much like wearing sunglasses inside and I couldn’t get used to them. I didn’t wear them long enough to see if they’d work. I’d say I tried them maybe 5 times for a few minutes at a time so they’re next to brand new. They’ve been sitting in the case in a drawer since 2022. I have the outdoor colorblind glasses but these might work for that as well; I never tried. I paid 246 for them (shipping and tax included in that number). Please see all photos for more details.
