A curable resin composition which can be continuously produced without gelling during the production and is excellent in basic performances including heat resistance and moisture resistance; an optical member which has excellent optical properties, e.g., high transparency, and shows excellent performance even in a severe use environment; and a method of regulating an optical material. The curable resin composition comprises an organic-resin ingredient and a metalloxane ingredient, wherein the organic-resin ingredient comprises a resin ingredient having an Abbe's number of 45 or larger and the metalloxane ingredient has a metalloxane bond. Also provided is an optical material comprising the curable resin composition. The optical member is obtained by curing the optical material. By the method, the Abbe's number and/or refractive index of an optical material is regulated. |
