Mirror lenses don't make your eyes hard to see through ◎ SPY goggles feature Happy Lenses, which are a favorite brand of mine because they allow you to see bumps and contours clearly even on cloudy days, and the serotonin effect makes for happy skiing/snowboarding ^^ (Please check the official website for details) Even with mirror lenses, it doesn't feel dark, and the visibility is good, so I've hardly used the spare lenses, but they can be easily swapped out with one touch. Spare lenses and a goggle case (bag) are also included. There are scratches on the lenses, so please check the photos. Five replacement lenses are also included. Please consider purchasing only if you understand that this is a used item. Thank you for looking.
