Abstract: A method for manufacturing a polarizing lens comprises 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 upper mold including the first resin composition and the polarizing film, 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 lens and the lower mold, and performing second polymerization on the upper mold including the gel-state upper lens coupled with the polarizing lens, the second resin composition, and the lower mold.
