PURPOSE:To obtain the optical product, such as eyeglass lenses and window glasses, having a clouding preventive effect superior in durability without impairing optical characteristics, such as surface hardness and reflection prevention. CONSTITUTION:The surface of the optical product containing silica or the like in the surface is treated with a silane coupling agent, and then, allowed to treat with a reactive surfactant by a photograft polymerization method, a radiation graft polymerization method, a graft polymerization method in an aqueous solution, or the like, thus permitting the silane coupling agent to strongly combine with the surface containing the silica and the surfactant to combine with the silane coupling agent, and consequently the surfactant to exist on the uppermost surface and the clouding preventive effect to be exhibited by its hydrophobicness. |
