摘要： A blocked lens assembly suitable for on-block processing and cleaning includes a blocked lens and a sealing member disposed on at least a portion of an edge and/or surface defined by the blocked lens. The blocked lens further includes a lens blank having a front surface and a back surface, a lens blocking piece to hold the lens blank while processing the back surface of the lens blank, and an adhesive layer, disposed between the front surface of the lens blank and the lens blocking piece, to affix the lens blank to the lens blocking piece. The sealing member protects the blocked lens so as to facilitate cleaning of the blocked lens while the lens blocking piece is affixed to the front surface of the lens blank
