Nylon polarized lens and moulding mold thereof
A nylon polarized lens includes a nylon material layer and a polarized film. The nylon material layer has four corners formed with positioning portions to position the polarized film. The nylon material layer has buffer grooves at two opposing end surfaces thereof. A moulding mold to manufacture a nylon polarized lens includes an upper die and a lower die. The lower die has a top surface which is an arc concave surface. Two opposing sides of the top surface of the lower die are formed with buffer flanges which are adapted to form buffer grooves of the nylon polarized lens. The top surface of the lower die is further formed with positioning portions to position the polarized film. The upper die has a bottom surface which is an arc convex surface. The upper die cooperates with the lower die to form a chamber for shaping the lens.
