Abstract
Protective eyeglasses provide hearing protection from elevated noise levels. The protective eyeglasses have safety lenses for protection of each of the eyes. Support members extend from the lenses of the eyeglasses to the ears, and have earplugs or protectors thereon which are inserted into the ears. The side support members are spring biased towards each other so that the side members provide pressure to hold the plugs in the ears of the wearer. Ear plugs are mounted so as to swivel relative to the side support members. The side support members are telescoping and are adjustable in length.
