ABSTRACT:
A method for manufacturing a correctable lens for glasses from an injectable thermo-plastic polymer material, or other moldable polymer, includes the step of molding a polymer blank provided with the contour of the corrective lens. The polymer blank is joined with a peripheral piece having the same internal radius of curvature as that of the polymer blank creating a lens blank. The internal face of the lens blank is ground and polished to obtain the desired ocular correction. The polymer blank is then separated from the lens blank, the lens blank now being the corrective lens ready for assembly with the frame.
