ABSTRACT:
A protective optical device is disclosed. The device includes a transparent shield for protecting a portion of the wearers face and a device for mounting an ophthalmic lens in the transparent shield. The mounting device includes an aperture through the transparent shield, a wall surrounding the aperture and extending forwardly from the shield to a front edge, and a shoulder surrounding the front edge for securing an ophthalmic lens to the front edge. The device allows standard ophthalmic lens to be securely mounted in a protective shield and minimizes the number of lens surfaces of the device.
