A composite functional polarized lens is a polarized lens in which lens substrate layers made of, for example, an allyl diglycol carbonate resin (produced by PPG Industries: CR-39), an urethane resin or other predetermined resin are integrally formed on both front and back surfaces of a polarizing film by way of insert molding, wherein a first lens substrate layer formed on the front surface of both the front and back surfaces of the polarizing film contains a light absorber which is an ultraviolet absorber, an infrared absorber, photochromic light absorber or a thermochromic light absorber as an additional component, and a second lens substrate layer formed on the back surface does not contain the light absorber. |
