ABSTRACT:
A method for manufacturing a lens with a lens barrel having a stopper by forming a uniform optical function coating on both lens surfaces. The method includes the steps of forming a first optical function coating on one side of a lens material, then inserting the lens material into a lens barrel so that the surface coated with the first optical function coating will face the long barrel side of the lens barrel, press molding lens surfaces by heating the lens material over its softening point, and finally forming a second optical function coating on the lens surface facing the short barrel side of the lens barrel.
