A pair of plastic glasses including a one-piece injection molded plastic lens and temple piece having an elongate lens portion, a pair of temple portions at the ends of the lens portion and a pair of straight hourglass hinges extending transversely of the lens and temple piece and joining the temple portions to the lens portion, the lens portion having a narrow central bridge and a pair of wide viewing lenses located between the bridge and the hinges, and a stiffening bar extending along the top of the viewing lenses and bridge, each temple portion extending a distance away from the adjacent hinge, said viewing lenses, bridge and temple portions all being formed from essentially uniform thickness light transmitting and optically clear plastic free of knit lines extending, with the exception of the stiffening bar, continuously from the top to the bottom of the lens and temple piece and, with the exception of the hinges, from the end of one temple portion across the lens portion to the end of the opposite temple portion, whereby the lens and temple piece is light transmitting through optically clear surfaces and forms a continuing shield surrounding the eyes from temple to temple; and a pair of earpieces adjustably mounted to the temple portions at locations away from the hinges.
