Abstract
A lens device includes a frame, at least one lens and two fasteners. The frame has at least a lens recess. The lens is embedded in the lens recess, and has an indentation located at an edge of the lens. The fasteners are disposed pivotally to the opposite sides of the frame, respectively, and each have an inner surface, a supporting surface and a hook portion. The inner surface adjoins the supporting surface. The hook portion protrudes from the inner surface. When the fastener rotates so that the hook portion enters into the indentation of the lens, the supporting surface of the fastener is disposed against a side of the indentation.
