Abstract
A laser level eyewear apparatus for providing a level indication visible by a wearer through the lenses comprises a pair of base glasses for wearing in front of a user's eyes having a frame, two modified lenses through which the wearer can look, a level projection assembly that is biased to return to and remain in an orientation to project a laser indication a level orientation through the lenses, and a battery that supplies electrical power to the level projection assembly. The frame defines a frame style similar to that in conventional eyeglasses, except that it not only holds the integrated, modified lenses in place over the eyes of one wearing the frame, its eyewire area is structured to surround the edges of the modified lenses so as to allow the laser from the level projection assembly to freely pass through the lenses.
