Are the lenses glass or polycarbonate?

They definitely are not glass but not sure about what type of plastic they are. I can tell you that I'm very happy with the pair I bought in 2021. They are my go sunglasses for all occasions and love their non-glare character for running and driving. I plan to replace with the exact same pair soon as I have worn out the the rubber nose pads. I don't give them any special treatment and they have held up well. Money well spent.

Are the lenses replaceable with prescription ones?

Thank you for your message. Unfortunately, we do not offer prescription glasses. However, our frames are fully compatible with prescription lenses. If you take your Knock frames to your local optometrist, they should be able to assist you with getting prescription lenses cut for our frames.

where are knock around sunglasses made?

Hi! Thanks for reaching out! Our sunglasses are manufactured in China. If you have additional questions, please feel free to get back to me. Thank you, Frank

Would these sunglasses fit a youth 10-12 old?

That depends on their head size. These are a pretty regular sized adult pair of sunglasses. If they typically wear that size, they should work.
