## Abstract

A method of manufacturing an optical lens including at least one electronic component. The method includes providing a mechanical reference system on an optical lens blank, the optical lens blank being configured to be processed to form the optical lens, providing edging data configured to be used to edge the optical lens blank to form the optical lens, and embedding the at least one electronic component in the optical lens based on edging data and on the mechanical reference system.

## Claims

### Claim 1

A method of manufacturing an optical lens comprising at least one electronic component, a mechanical reference system being provided on an optical lens blank, the optical lens blank being configured to be processed to form the optical lens, the method comprising:
obtaining edging data configured to be used to edge the optical lens blank to form the optical lens;
edging the optical lens blank based on the edging data and on the mechanical reference system to form the optical lens; and
embedding the at least one electronic component in the optical lens based on the edging data and on the mechanical reference system, wherein
the embedding is performed by an edging device that comprises a tool arranged and configured to pick and place the at least one electronic component in the optical lens.

### Claim 2 (depends on 1)

The method according to claim 1, further comprising removably attaching a blocking piece to a surface of the optical lens blank, the blocking piece forming the mechanical reference system.

### Claim 3 (depends on 1)

The method according to claim 1, further comprising obtaining lens data with respect to the mechanical reference system, the lens data comprising:
a position of an optical centre of the optical lens to be manufactured, and/or
an orientation of an optical axis of the optical lens to be manufactured, and/or
an optical power of the optical lens to be manufactured, and/or
a position of a contour of the optical lens to be manufactured, and/or
a thickness of the optical lens to be manufactured for a plurality of points of the surface of the optical lens blank, and/or
a curve radius of a first and a second surface of the optical lens to be manufactured, wherein
the at least one electronic component is further embedded in the optical lens based on the lens data.

### Claim 4 (depends on 1)

The method according to claim 1, further comprising printing a coating to protect at least a predetermined areas of the at least one electronic component embedded in the optical lens.

### Claim 5 (depends on 1)

The method according to claim 1, further comprising:
obtaining data of the at least one electronic component; and
processing the optical lens blank based on data of the at least one electronic component, on the edging data, and on the mechanical reference system to form a cavity for receiving the at least one electronic component.

### Claim 6 (depends on 1)

The method according to claim 1, further comprising forming an other reference system on a surface of the optical lens, and the at least one electronic component is embedded in the optical lens based on edging data and on the other reference system.

### Claim 7 (depends on 6)

The method according to claim 6, wherein the other reference system is formed during the edging of the optical lens blank.

### Claim 8 (depends on 7)

The method according to claim 7, further comprising surfacing at least a surface of the optical lens blank, and wherein the other reference system is formed during surfacing the optical lens blank.

### Claim 9

A system for manufacturing an optical lens comprising at least one electronic component, a mechanical reference system being provided on an optical lens blank, the optical lens blank being configured to be processed to form the optical lens, and edging data being provided that is configured to be used to edge the optical lens blank to form the optical lens, the system comprising:
an edging device configured to
edge the optical lens blank based on the edging data and on the mechanical reference system to form the optical lens, and
embed the at least one electronic component in the optical lens based on the edging data and on the mechanical reference system, wherein
the edging device comprises a pick and place electronic component tool, which is arranged and configured to directly pick and place the at least one electronic component to be embedded in the optical lens.
