Abstract: Adjustable focal length eyewear (11) comprising two lenses (21, 22) that are mounted to a frame (14, 15, 16) for supporting the lenses (21, 22) in front of a user's eyes. At least one of the lenses (21, 22) is a variable focal length lens of the kind comprising two superposed lens elements (31, 41) having cooperating optical surfaces that are shaped such that the focal length of the variable focal length lens (21, 22) is variable according to the relative lateral disposition of the lens elements (31, 41). One of the lens elements (31) is fixedly mounted to the frame (14, 15, 16) and the other lens element (41) is movable manually relative to the fixed lens element (31) for varying the focal length of the variable focal length lens (21, 22).
