Love them!

I absolutely love my new glasses! I have a pair of non-rx Fort Knocks sunglasses that I love but I wasn't sure if it would translate over to rx clear lenses, so I gave it a try and I'm only sorry I didn't get them sooner. They're stylish. I love to splash of color green glasses gives my vibe. I would highly recommend any Knockaround glasses to anyone.

Prescription glass

Very satisfied, brown lenses take some getting used to as everything has a yellow glow , probably should have gone grey but I like the look.

Love these

So excited to be able to get quality RX lenses in the frames I’ve come to love over the years. Great value, super sturdy and the lenses have sharp focus and are really dark.
