If you read OpticalOwl's article on Collection by Fetch which is a new line by Fetch Eyewear. The new frames line allows a glasses wearer to keep the same lenses and swap them out into different frames. This allows people to change the colors of the frame and keep the same style glasses.
It's a smart eyeglasses invention and technology and I'm surprised we haven't seen anyone glasses company come up with this before. This is a video demonstrating the Collection by Fetch frames from Fetch Eyewear.
