Abstract: Eyewear comprising a pair of lenses assembled to a frame. Each lens comprises an integral tubular loupe mounting bracket extending forward of the lens exterior surface. The tubular mounting bracket defines an interior surface. The interior surface provides a loupe coupling receptacle for receiving and temporarily retaining a loupe assembly therein, enabling replacement of each loupe for repair, change in magnification, reduction in overall costs, reduced delivery time, etc. The loupe assembly is temporarily fixed within the loupe coupling receptacle by a loupe retention element feature. The lenses can be manufactured of a generally planar or curved shaped clear, translucent, or opaque material. The lenses can be adjustably assembled to the frame, enabling adjustable positioning of each loupe. Accessories, such as a camera, lighting, a secondary lens frame (such as prescription lenses), etc. can be integrated or removably attached to the eyewear frame.

Abstract: The present invention relates to a pair of glasses with polarized or prescription lenses that can be adjusted to provide two different looks. Rotatable side arms connected to the main frame through a leg seat and a rotating secondary frame provide a mechanism to interchange the interior and exterior sides of the glasses. A correct lens orientation indicator on the secondary frame ensures correct configuration. In addition, the proposed mechanism offers two folding styles, in the first one both side arms are folded next to each other at the same side of the main frame. In the second, the side arms are folded on opposite sides of each other. Furthermore, the present invention provides a simple mechanism to turn smart glasses on and off. If the camera placed on the side arm is facing outwards, the smart glasses turns on. When the camera faces inwards, the smart glasses turns off.

Abstract: Eyewear can include lenses having perimeters that are customized for an intended wearer. The perimeter of the lenses can be determined based on anatomical features of the wearer's face, the wearer's field of vision, or other parameters specific to that individual. Determination of the lens perimeters can involve developing a three-dimensional model of a wearer's face and/or head, demarcating a lens perimeter over an obtained image of a user's face, or delineating the boundary of a wearer's peripheral vision. A provisional lens perimeter obtained by any of these methods may be modified in curvature and/or size to arrive at a desired final lens perimeter. Customized lenses can be fabricated based on the determined lens perimeters. The customized lenses can be assembled into completed eyewear that is customized for a wearer, for example having shapes, sizes, and designs not otherwise possible.
