Claim 5:
6. An eye shield, comprising
a frame having a plurality of receivers located along the frame and a plurality of latches located to cooperate with the receivers,
each of the receivers comprising an elongate cavity having an open front with a sloped entrance wall extending upwardly from the open front at an angle, and a catch wall located behind the sloped entrance wall, the catch wall defining a catch surface,
each of the latches comprising a flap hingedly connected to the frame, and a window formed on and extending though the flap and configured to impart flexion to the flap when pressure is applied to a lower edge of the flap, an elongate catch extending upwardly at an angle from an inner surface of the flap corresponding substantially to the angle of the sloped entrance wall, and a tooth projecting from a distal end of the elongate catch and configured to engaging the catch surface of the catch wall; and
a lens having a plurality of spaced apart lens apertures extending through the lens and located so as to align with the receivers of the frame when the lens is positioned for installation onto the frame;
wherein, the latch is engageable with the receiver by rotating the latch to pass the elongate catch into the receiver through the aligned lens aperture and the open front of the receiver to latchingly engage the tooth with the catch surface of the receiver in a snap-fit frictional relationship, and
wherein the latch is selectively disengageable from the receiver by applying force to a lower edge of the flap and flexing the lower edge of the flap rearward slightly to disengage the tooth from the catch surface.
