How do you change the lens?

I don't think they can be changed out. I was looking at mine set and the way the frames are made I couldn't see anyway to taking them out. Unless you take a chance on breaking the lens out. Sorry I couldn't have been more helpful to anyone

Are all the lenses uv400?

Yes they are! We also have lens accessory set to sell separated, all UV400, here it is the link: https://www.amazon.com/dp/B08RHKWDKV?ref=myi_title_dp
