Abstract
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.

Total Claims: 9
Claim 1
Independent Claim
212 words
Laser safety eyeglasses comprising: two protective filters for protecting the eyes against radiation from a laser; a frame having a main body defining two holders for accommodating said protective filters, respectively, and having two arms hinge connected to said main body, said main body including a bridge for interconnecting said holders and having an upper edge and an outer face facing away from the wearer; said holders being annular members having respective upper portions; a plurality of shielding plates made of a predetermined metal for shielding the wearer of the eyeglasses from laser radiation, a first two of said shielding plates being mounted on corresponding ones of said arms at the ends thereof connected to said main body so as to cover over the region between said frame and the face of the wearer, and a second two of said shielding plates being mounted on said upper edge above corresponding ones of said holders and extending inwardly toward the face of the wearer so as to cover over the region between said frame and the face of the wearer; and, shielding metal means for covering at least said outer face at said upper portions and said bridge, said shielding metal means being made of a metal plate having a good heat conductivity.
