Shimano S-PHYRE CE-SPHR2 Magnetic Spare Lens Description:

Ideal for lowlight and wet riding conditions, the Ridescape Cloudy (CL) spare lens delivers 82% light transmission for better visual performance when its cloudy, rainy, or dark. They also feature an anti-reflective treatment that reduces oncoming headlight glare and there is a hydrophobic coating on all outer and inner lens surfaces that increases water and sweat repellency to keep lenses free from dust, oil, and dirt so they stay cleaner longer and are easier to maintain.
