I received this as a gift, so I don't have all the details. I was told it was purchased at a local eyeglasses store. Upon close inspection, there are some scratches, but it doesn't look like it's been heavily used. I think the light-blocking ability is high. The RB2132F New Wayfarer is a slightly smaller redesign of the original Wayfarer. It's a smaller size, updated to be softer and more stylish.
