We never take clear vision for granted, so that you can. The Smith Reason OTG goggles are over-the-glasses and optical docking system compatible (ODS). In other words, you can wear them over your prescription glasses or use our ODS prescription lens insert to maintain the sharpest vision possible. Designed with larger face shapes in mind they provide a helmet-compatible, pressure-free fit that lets your glasses sit naturally for comfort that lasts all day. The ventilated design regulates air flow for a fog-free view even when wearing a helmet. Fine tune your kit with additional or replacement goggle lenses for sunny conditions, variable conditions, and cloudy conditions. Expand your view here.
