Abstract
An edge of a lens blank an eyeglass lens having a shaped edge is measured at a plurality of peripherally offset measuring positions and respective control values are generated corresponding thereto and supplied to an applicator. This applicator applies a hardenable material in liquid form to the edge of the eyeglass lens and is controlled such that an amount and/or position of the material is applied at the measuring positions according to the respective control values in a controlled manner. The hardenable material is chemically or radiation-cured to form on the edge of the lens a functional layer that has an optical, magnetic, electric, or electronic function.
Claims8
A method comprising the steps of:
- machining from a lens blank an eyeglass lens having a shaped edge;
- measuring a thickness of the edge of the eyeglass lens at a plurality of peripherally offset measuring positions and generating respective control values corresponding thereto;
- supplying the control values to an applicator;
- applying with the applicator a hardenable material in liquid form to the edge of the eyeglass lens;
- controlling the applicator such that an amount and/or position of the material is applied at the measuring positions according to the respective control values in a controlled manner;
- and
- chemically or radiation-curing this material to form on the edge of the lens a functional layer that has an optical, magnetic, electric, or electronic function.
