I love these glasses, class style.

Good value

Bought these as a second pair, they would do if my others broke but the frame was a bit thicker than I was expecting hence not wanting to wear them all the time

Great!

Ordered two pairs, both great. Make sure you size them up against your current glasses or else you'll end up with either massively oversized or tiny. In hindsight, I might not have put the blue light filter on my lenses, but it does seem to help me sleep better, so the little yellow tinge may be worth it.

Great value

Glasses are a good design that fit well for my small face as most glasses tend to be too big.
