OPTICAL COMPOSITION FOR BLOCKING ELECTROMAGNETIC WAVES AND METHOD FOR MANUFACTURING OPTICAL LENS THEREFROM
The present invention relates to an optical composition for blocking near-infrared rays, comprising a mixture of a polyurethane-based thermosetting resin composition and a near-infrared absorbent, wherein the optical composition for blocking near-infrared rays comprises (1) at least one of polyisocyanate compounds in a liquid phase (I); (2) at least one of polyol or polythiol compounds in a liquid phase (II); and (3) a near-infrared absorbent having a high near-infrared absorbing ability of less than 5% in the range of 800-1000 nm, and to a method for manufacturing near-infrared blocking spectacle lens using the same. The spectacle lens obtained from the optical composition of the present invention can effectively prevent damage to the retina by effectively blocking near-infrared rays.
