Where can I get glasses with 100% UV protection at a reasonable price?

My eye area is very sensitive, so I’m looking for sunglasses that provide 100% UV protection, preferably UV400.

I have already visited one or two shops, but I couldn’t find proper glasses with 100% UV protection.

If anyone has personally bought them or knows a reliable place where I can get them, please let me know. I’d really appreciate your suggestions, especially if they are available at a reasonable price.
