Abstract: A system with a pair of glasses, such as sunglasses, having a frame and at least one lens mounted in the frame, a light sensor mounted on the frame, and a receiver and circuitry present in the frame. The system also has app (e.g., on a cell phone) having control logic that is configured to send a command to the glasses to change the lens to a first or “dark” tint setting when a reading of the light sensor exceeds a high threshold and to send a command to change the lens to a second or “light” tint setting when a reading of the light sensor drops below a low threshold. The tint settings may change the transmittance or opacity of the lenses or the color of the lenses.
