Abstract A pair of louvered sunglasses includes a frame having a front piece with a pair of lens openings therein and a pair of temples attached to the front piece. A plurality of elongated louvers are horizontally mounted in each front piece opening and rotatably supported in each vertical edge of the front piece. Each louver has a small shaft on each end riding in an opening along each vertical edge of the frame front piece and each louver has an arm protruding therefrom and each arm of each louver in each opening being connected by a connecting member. The connecting member is connected to a rotating shaft passing through the top of the frame front piece so that rotating the shaft rotates all of the louvers simultaneously.
