Abstract
A dual ophthalmic lens machining platform comprises a blocked lens mounting structure constructed to simultaneously receive a first and a second blocked lens blank, and configured to rotationally and linearly move each lens blank, wherein the first and second lens blank have at least one common axis of movement on the mounting structure; and at least one machine tool adapted to machine each lens blank. A method of manufacturing ophthalmic lens comprises the steps of mounting at least a first and a second blocked lens blank on the machining platform; and simultaneously performing at least one machining process on the two blocked lens blanks on the machining platform. The dual ophthalmic lens machining platform is configured to simultaneously receive and machine a left and a right blocked lens blank for forming a left and a right lens of a pair of eyeglasses.
