摘要： The method of making plastic lenses ready for fitting to the contour of the wearer's eye comprising supporting a blank of plastic at one end for rotation about a predetermined axis, turning the blank down to a predetermined diameter, making an annular face cut at the distal end of the blank of predetermined radial width, making a spherically concave base cut at said distal end of predetermined depth relative to said annular face cut, reversing the blank end-for-end, making a first spherically convex cut at said end of the blank of a predetermined radius such that the distance between the inner and outer surfaces is of a predetermined thickness and making a flange cut at the marginal edge of the outer convex surface of lesser radius of curvature; and apparatus for carrying out the method.
