Claim:
1. A method for manufacturing a polarizing lens, the method comprising: taping an upper mold using first tape; applying a first resin composition onto a concave surface of the upper mold; forming a polarizing film on the first resin composition; performing first polymerization on the first resin composition to form a gel-state upper lens; spacing the upper mold apart from a lower mold; taping the upper mold and the lower mold using second tape; injecting a second resin composition into a space between the polarizing film and the lower mold; and performing second polymerization on the gel-state upper lens and the second resin composition, wherein the first polymerization includes pre-heating preformed for about five minutes at about 15° C. and polymerization performed for about six hours at about 15° C., for about four hours at about 15° C. to about 60° C., for about ten hours at about 60° C., and for about two hours at about 60° C. to about 15° C.
