The present invention relates to a urethane-based optical resin composition having a high heat deformation temperature and a manufacturing method of an optical lens using the same, more particularly excellent in light weight, moldability, dyeing, transparency, impact resistance, and the like, in particular the initial heat deformation temperature The present invention relates to a monomer composition for plastic optical lenses having a low central deformation of the lens, a small multi-film cracking phenomenon of the lens due to heat, and excellent thermal stability and a low color change due to heat, and a method of manufacturing an optical lens using the same. |
