<p>In manufacturing a contact lens from a contact lens raw material or work, a base curve and a bevel are formed by first machining means (204) on the basis of design data calculated by first design data calculating means (202), the radius of curvature of the base curve is measured by measuring means (205) and the radius-of-curvature data of a front curve for attainment of a desired refractive power is calculated by second design data calculating means (203), and then, the front curve, together with a lentic curve if necessary, is formed by second machining means (206) on the basis of the calculated data. The front curve may be formed before the base curve is formed In polishing, a soft polishing cloth is pressed against the work with fluid pressure while causing relative motion therebetween. In securing the work to a mounting tool, the necessary amount of an adhesive agent is determined considering the space into which the adhesive agent is to be discharged.</p> |
