Abstract: Eyewear is configured to use pairs of polarized lenses, with one pair held stationary within an eyeglass frame, and the remaining pair disposed adjacent with the fixed pair and permitted to rotate under the control of the wearer. A novel mechanism is included within the eyewear for the wearer to use in rotating the movable lenses with respect to the fixed lenses. In particular, a flexible member is included to surround a majority of each rotatable lens, with the flexible member riding within a channel formed in the frame. A lever, or other type of hand control fixture, is attached to the flexible member. The wearer may than move the lever back and forth, which imparts a linear motion to the flexible member. The linear motion of the flexible member is translated into a rotational movement of the attached lenses, thus creating a wearer-adjustable tint.
