Claim:
1. A laser protection lens comprising: a) an optically transparent material having a perimeter shape that follows a contour of a user's eye socket ridge, a horizontal shape, and a vertical shape, wherein the horizontal shape comprises at least two different angles with respect to a normal of the plane of the user's face defined by a line oriented parallel to a line connecting the center of both eyes that passes though the glabella and by a line connecting the glabella to the subnasale; and b) a multilayer interference coating applied to at least one of an inside and an outside surface of the optically transparent material, the multilayer interference coating having a spectral filter profile with at least 20 dB reduction of optical transmission for at least one of 445 nm, 532 nm, and 610 nm wavelength light propagating at angles within forty-five degrees with respect to the normal of the plane of the user's face.
