Yes! Your 10$ and 600$ are made in the same place by the same company with largely the same materials.
I discovered goodr recently and they are great. 25$ high quality sunglasses that I can actually trust have real UV ratings. Seeing people wear ray bans or oakleys is really funny
Thankfully in the EU you are not even allowed to sell sunglasses without proper UV protection, and can just pick up sunglasses from any market and trust they are fine, if a little flimsy.
EDIT: ok apparently anywhere else than the poorest of countries, too, really.
