## Abstract

On a first aspect, the spectacle lens is selected as including a transparent support in which is coded an identifier readable by an external reading tool for retrieving the identifier. A distant server is contacted using the identifier and data related to the spectacle lens is so gathered. On a second aspect, data related to the spectacle lens is provided to a predetermined database. Upon receiving a request issued from a requester, the database is accessed and at least some of the data is retrieved, the request including at least part of the identifier, and the retrieved data is sent to the requester.

## Claims

### Claim 1

A method for monitoring a spectacle lens, comprising:
a) selecting said spectacle lens as including a transparent support in which is coded an identifier readable by an external reading tool for retrieving said identifier;
b) reading said support using the external reading tool and retrieving said identifier;
c) contacting a distant server using the identifier; and
d) gathering from the distant server data related to the spectacle lens.

### Claim 2 (depends on 1)

The method according to claim 1, wherein the spectacle lens is already in a form of a trimmed lens having a contour in accordance with a shape of a frame in which the spectacle lens is to be mounted and wherein the support is incorporated in a location of the spectacle lens selected to still belong to the trimmed lens.

### Claim 3 (depends on 1)

The method according to claim 1, wherein the monitoring is performed at predetermined portions of a lifetime of said spectacle lens, including at least one mounted-in-frame portion in which the spectacle lens is mounted in a frame.

### Claim 4 (depends on 1)

The method according to claim 1, wherein said support is a reflective-transmissive pattern formed on a font face of the spectacle lens, visible on a side of the front face.

### Claim 5 (depends on 1)

The method according to claim 1, wherein said support is a reflective-transmissive pattern formed on a font face of the spectacle lens, visible on a side of the front face; and wherein said step of reading said support with said external reading tool for retrieving said identifier is carried out by taking a photograph or video of said pattern and by analyzing said photograph or video or having it analyzed or sent to a server for analyzing.

### Claim 6 (depends on 1)

The method according to claim 1, wherein said support is a RFID device.

### Claim 7 (depends on 1)

The method according to claim 1, wherein said support is a RFID device; and wherein said step of reading said support with said external reading tool for retrieving said identifier is carried out by receiving said identifier from said RFID device through a RF reader, such as one using a NEC protocol.

### Claim 8 (depends on 1)

The method according to claim 1, wherein in said step of reading said support with a reading tool for retrieving said identifier, said reading tool is a consumer product configured to be connected to an external network including Internet.

### Claim 9 (depends on 8)

The method according to claim 8, wherein in the consumer product is a portable or mobile device, including smartphone, touchpad or tablet computer, PDA or the like, configured to connect directly or indirectly to the Internet by use of wireless communication means.

### Claim 10

A method for monitoring a spectacle lens, comprising:
a) allocating to said spectacle lens an identifier that is unique to said spectacle lens;
b) incorporating into said spectacle lens a transparent support in which is coded said identifier so that said support is readable by an external reading tool for retrieving said identifier;
c) providing data related to said spectacle lens to a predetermined database, before or after step b);
d) upon receiving a request issued from a requester, accessing the database and retrieving at least some of said data, the request including at least part of the identifier;
e) sending the retrieved data to the requester; and
f) optionally, either before step b) or after step e), receiving new data related to said spectacle lens and adding said data into the database.

### Claim 11 (depends on 10)

The method according to claim 10, wherein said received request issued from a requester includes a variable related to a nature of the requester, and the data sent back toward the requester depends both on the identifier and on the nature of the requester.

### Claim 12 (depends on 10)

The method according to claim 10, wherein the monitoring is performed at predetermined portions of a lifetime of said spectacle lens, including at least one mounted-in-a-frame portion in which the spectacle lens is mounted in a frame; and wherein said step of accessing the database is performed using a computer system which includes an entry point, said entry point including a monitoring variable interactive managing routine for updating a monitoring variable having a current value representative of a current one of said portions of the lifetime of said spectacle lens, and said step of accessing the database includes accessing said entry point and carrying out said monitoring variable interactive managing routine.

### Claim 13 (depends on 12)

The method according to claim 12, wherein said computer system includes for at least one not-yet-mounted-in-a-frame portion a database section that contains data representative of physical parameters in relation to manufacturing of said spectacle lens.

### Claim 14 (depends on 12)

The method according to claim 12, wherein the monitoring is performed at predetermined portions of a lifetime of said spectacle lens, including at least one mounted-in-a-frame portion in which the spectacle lens is mounted in a frame; and wherein said computer system includes for said at least one mounted-in-a-frame portion a database section that contains data representative of optical properties of said spectacle lens.

### Claim 15 (depends on 14)

The method according to claim 14, wherein said optical properties include at least one of a spherical power and a cylindrical power.

### Claim 16 (depends on 14)

The method according to claim 14, wherein said database section that contains data representative of optical properties of said spectacle lens also contains data representative of physical parameters in relation to servicing of said spectacle lens.

### Claim 17 (depends on 14)

The method according to claim 14, wherein said database section that contains data representative of optical properties of said spectacle lens also contains information representative of optical properties of a pair of spectacles in which is mounted said spectacle lens.

### Claim 18 (depends on 14)

The method according to claim 14, wherein said database section that contains data representative of optical properties of said spectacle lens also contains data representative of optical properties of the other spectacle lens in a pair of spectacles in which is mounted said spectacle lens.
