Abstract

Laser safety eyeglasses include two protective filters for protecting the eyes against radiation from a laser. The eyeglasses include a frame having a main body defining two rims for accommodating the respective protective filters therein. Metal shielding plates are attached on the upper side of the frame as well as at the hinge ends of both mounting arms. The shielding plates stretch across the respective free regions between the frame and the face of the user. The mounting rims in which the protective filters are received as well as their connecting bridge are at least partially made of the same metal as the shielding plates.
