Abstract: A pair of smart glasses having interfering light filtering includes a glasses frame defining a horizontal view path and a semi-transparent display supported on the glasses frame and positioned in the horizontal view path. A projection mechanism is supported on the glasses frame and has a projection lens positioned above the horizontal view path. The projection mechanism is configured for projecting virtual content on the semi-transparent display, with an outer surface of the projection lens facing a rear facing surface of the semi-transparent display. A semi-transparent polarized shield is supported on the glasses frame and is positioned below the horizontal view path, with an inner surface of the semi-transparent polarized shield facing the outer surface of the projection lens. The semi-transparent polarized shield positioned to filter interfering light passing through the semi-transparent polarized shield and toward the projection lens.
