ABSTRACT:
According to the present invention, a plurality of first lens elements each having specific lens optical values and a plurality of second lens elements each having specific lens optical values are kept in stock; each one of the first and second lens elements are selected from those kept in stock, based on optical calculation; and these two lens elements are laminated to form an opthalmic lens meeting a desired prescription. Accordingly, the present invention has advantages such as shortening of the period from order receiving to product delivery.
