Abstract
Disclosed embodiments relate to eyewear configured to reduce stray light. An exemplary embodiment of the eyewear accounts for various design factors, including the cross sectional profile of the rim, the micro topography of the rim surface, the reflectivity, the theatre or room geometry, proximity of the eye to the lens, lens size, and the screen gain. An exemplary eyewear includes lenses connected to the rim sections of a frame, and a path may be defined through a maximum height of the outer flange portion of a rim section and a maximum height of the inner flange portion of the rim section. The path may be inclined at an angle relative to an angle α relative to a longitudinal axis defined by the lenses.
