ABSTRACT:
A method of forming a polarized optical lens including an optical lens of certain curvature and a polarized piece, wherein the polarized piece is made up of cellulose protective film, adhesive and polarized thin film, and is pressed to matched curvature as injected and plasticized optical lens. The cellulose protective film of the polarized piece is then peeled off, and through the use of injection and plasticization principle, polarized thin film is combined and pasted to the inner surface or outer surface of the optical lens. This synthesized lens is then placed in the ring of an optical mold. Light adjustment and color change liquid colophony is then injected through a through-hole in the ring, and through the clamping of synthesized lens and light adjustment and color change liquid colophony, the whole set then solidifies and forms a shape.
