Abstract: It is a pair of glasses capable of producing a 3-D visual effect, mainly including a frame, two polarizing lenses set in the frame, and two additional lanminated lenses removably disposed either in front of or behind the two polarizing lenses. The laminated lenses each consists of two glass sheet layers, an LCD layer between the two glass sheet layers, and a polarizer layer attached to an outer side of one of the two glass sheet layers. When a voltage is applied to the LCD layer, molecules constituting the LCD layer rotate and change their arrangement directions to produce light blocking effect, enabling the glasses to be used as an LCD shutter glass for watching a 3-D image system. When the additional laminated lenses are removed, the glasses can be used as a normal sun glass.
