Abstract: The invention is directed to a spectacle lens which contains an infrared absorbing agent, and which shows excellent infrared absorbing properties by minimizing deterioration and decomposition of the infrared absorbing agent, and as well as a method of producing such an optical lens. This infrared absorbing spectacle lens is formed by adding an infrared absorbing dye to a polyurethane resin obtained by addition polymerization of a prepolymer produced by reacting a polyisocyanate with a polyhydroxy compound, and an aromatic polyamine. The lens shows excellent infrared absorbing properties with no deterioration or decomposition of the infrared absorbing agent. It is possible to prevent deterioration of the infrared absorbing agent due to additives such as peroxides (including polymerization catalysts and initiators such as benzoyl peroxide), as well as increased absorption of visible light, which was difficult with conventional resin materials for molding.
