Lightweight, frameless protection. Superior comfort and fit. Scratch resistant polycarbonate lens provides 99% UVA/B/C protection. Frameless eyewear perfectly couples simplicity and style allowing them to work in applications and environments where a full field of vision is ideal, if not essential. Because they are lightweight and provide the wearer with an unobstructed view, they are excellent choices for those who are required to wear eye protection for long periods of time.
