AGENT AND METHOD FOR REMOVING FOREIGN MATTER FROM LENS MATERIAL FOR EYE AND JIG FOR MANUFACTURING LENS FOR EYE

摘要

PURPOSE:To obtain the foreign matter removing agent for the lens material for eye and eye lens manufacturing jig and the removing method which uses the agent by using a pressure-sensitive adhesive as the removing agent which removes sticking foreign matter. CONSTITUTION:When the lens material for eye is cut, the specific pressure sensitive adhesive 2 is used as the removing agent for removing foreign matter such as dust and dirt sticking on the surface of the eye lens material 1 and manufacturing jig. For example, a block-shaped lens material 1 and the manufacturing jig 3 are brought into contact with the pressure-sensitive adhesive 2 to remove the foreign matter sticking on their surfaces by adhering it to the pressure-sensitive adhesive 2. At this time, the pressure sensitive adhesive 2 is shaped preferably in conformity with the surface shape of the surface of the lens material 1 and the surface shape of the jig 3 so as to increase the contactness between both. Then the lens material 1 and manufacturing jig 3 while adhered together are machined by cutting, polishing, etc., to manufacture a target eye lens.
