<p>The present invention relates to a resin composition for a urethane-based optical lens and an optical lens hardened using the same, wherein a shock resistance problem which can be both an advantage and a weakness of an existing plastic optical lens is resolved. The resin composition of the present invention includes a polythiol compound and a polyisocyanate compound. The urethane-based optical lens obtained by reacting the same has low specific gravity, is lightweight, and has excellent heat resistance, workability such as molding properties and coloring properties, and various optical properties such as UV blocking properties and transparency. In particular, a problem in which shock resistance is reduced after hard-multi-coating can be solved.</p> |
