The lenses are made of crystal glass in the signature Ray-Ban G-15 color. You will need to have them installed in your frame by an optician. Many opticals provide this service for free. Size 59mm Please make sure this is the correct size for your frame. You will likely find the size stamped on the earpiece of your frame. It should say 59-17. If you have any questions about this, feel free to message me. The unique Ray-Ban G-15 tint boosts contrast, making it easier to distinguish between objects and colors in an outdoor environment. 100% UV Protection. The left lens is etched with RB. The Ray-Ban box is just for display and is not included. I will wrap the lenses carefully before shipping.
