SUPER-HIGH REFRACTIVE INDEX OPTICAL RESIN COMPOSITION HAVING HIGH HEAT DEFLECTION TEMPERATURE AND EXCELLENT THERMAL STABILITY, OPTICAL LENS USING SAME AND METHOD FOR MANUFACTURING THE OPTICAL LENS
The present invention relates to a urethane-based optical resin composition having a high heat deflection temperature and a method for manufacturing an optical lens using the composition. A monomer composition for a plastic optical lens according to the present invention is lightweight and has excellent plasticity, dyeability, transparency, shock resistance, etc., and especially has a high initial heat deflection temperature, thereby reducing central deformation of the lens and cracking of the multi-film of the lens due to heat. Further, the monomer composition has excellent thermal stability to reduce discoloration of the lens due to heat.
