Switch Avalanche Slide Sunglasses Information The Avalanche Seals off stray rays of light that can impede vision, while enabling air to flow through the vented nose pad and across the eye to limit fog build up. Temple tips are encased in TPR rubber to minimize slipping, while formed in a 3D shape that holds the sunglass behind and below the ear.

Avalanche can take a pounding but stay in front of your eyes, providing unobstructed vision. The Slide shape lens provides excellent light coverage but has a shallower vertical depth and a narrower horizontal width than the Upslope.

This makes an excellent choice for use as an RX sun, as well as a standard sunglass. Eyesize: 63/17 TL: 135 (See "More Help" tab for eyesize information) All kits include 2 lenses, either one polarized or non-polarized lens, and one pair of low light Rose Amber lenses.

Also included is a microfiber cleaning pouch and one magnetic lens pod to hold the extra set of lenses. Additional lens colors available as replacement lenses.

Sun Readers replacement lenses also available. For full lens color descriptions and technology, see Switch Lens Technology.
