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