It really has changed. I noticed it a few months back. Subtle rightwing and like, morbid “shock” content and even some animal abuse started popping up more and more. I just gradually started using it less and less, it was pretty obvious what was going on.
I’ve had pretty decent luck ordering prescription glasses from the big online glasses retailer, you know the one, starts with a Z.
I still gotta pay $100 for glasses but that’s way better than the $400 they cost retail.
