METHOD FOR MANUFACTURING POLARIZING LENS AND POLARIZING LENS MANUFACTURED BY THE SAME

摘要

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.

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 fllm 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 performed 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.
