For wearers who rely on prescription glasses to see clearly at work, get the Pyramex OTS safety glasses. These safety glasses are essential for indoor and outdoor work, particularly those exposed to debris, such as construction, automotive repair, handyman services, and more. With their bulky design, these safety glasses can fit most of today's prescription glasses, particularly frames for up to 5 3/8" width and 1 3/4" height. However, they have lightweight nylon temples that you can adjust easily for length and pitch. These safety glasses also come with a single-lens design for a superior front and side protection. Furthermore, the Pyramex OTS safety glasses are available in seven lens colors and have an ANSI Z87+ rating.
