How do liquid-cast urethane lenses compare to glass lenses?Updated a year ago

Glass lenses are a benchmark in terms of optical clarity. However, they offer minimal impact resistance and are the heaviest lenses on the market. Consequently, they are not suitable for action sports and an active lifestyle. We decided to use liquid-cast urethane lenses of the highest optical grade for numerous reasons: they offer the best impact resistance and durability. By liquid casting our lenses in glass molds, we ensure they’re free of distortion. In addition to offering crystal clear vision, urethane lenses are exceptionally light and provide excellent scratch and shatter resistance.
