Wiley X Sunglasses JP-2 model Gloss Black frame with LA Light Adjusting lenses. These lenses lighten and darken depending on the amount of Ultraviolet Light exposure. Inside and under lower UV conditions they are pale grey as shown in the photo. Outside they become a darker grey shade according to the amount of UV light. Note even under strong UV conditions they do not get as dark as a regular sunglass tint (such as the polarized lenses) but are convenient for changing light conditions and especially if you do not require a dark lens for daytime use. This goggle in a sunglass concept provides incredible wind, sun, glare, and debris protection. The Ultra foam gasket snaps on and off with Seal-Tek technology so you can convert your Wileys from a goggle to a sunglass in seconds. Ballistic polycarbonate lenses are scratch resistant and anti-fog coated providing all weather, all terrain
