The Bobster Road Master combines the best of Interchangeable Eyewear and Transitional Lenses. The quick-snap adjustable strap allows easy conversion from sunglasses to goggles and back, while the anti-fog, photochromic lenses automatically react to temperature and the amount of exposure to ultraviolet (UV) light. Made of shatter-resistant polycarbonate, the lenses comfortably and naturally darken in the sun and lighten indoors in 1-2 minutes. The closed cell memory foam provides added comfort and protection from wind and dust.
*Please note that while these glasses would presumably pass ANSI Z87.1-2010 standards, they are NOT certified, and are therefore not endorsed as safety eyewear by Safety Glasses USA.
