Method for updating an index of a person

1. A method for updating an index of a person, the method comprises:

obtaining the index of the person, which is defined as a function of at least one life parameter of the person;

monitoring the at least one life parameter of the person over time;

updating the index of the person based on evolution over time of the at least one life parameter of the person,

wherein the index of the person corresponds to a vision capital of the person, the vision capital providing an indication of eye health of the person and the at least one life parameter of the person is a visual behavior parameter relating to visual behavior of the person, the visual behavior parameter of the person relating to a visual effort of the person.

2. The method according to claim 1 , wherein the index obtained during the index obtaining is further defined based on at least an additional parameter intrinsic to the person.

3. The method according to claim 1 , wherein the index of the person is a function of at least one parameter of environment of the person, and evolution over time of the at least one parameter of the environment of the person is monitored during the monitoring, and the index of the person is updated based on the evolution over time of the at least one parameter of the environment of the person.

4. The method according to claim 3 , wherein the parameter of the environment of the person relates to spectral features and intensity of light received by the person.

5. The method according to claim 1 , wherein the index of the person is a function of at least one parameter of physiology of the person, and evolution over time of the at least one parameter of the physiology of the person is monitored during the monitoring, and the index of the person is updated based on the evolution over time of the at least one parameter of the physiology of the person.

6. The method according to claim 1 , wherein the index of the person is a function of at least one parameter of life habit of the person, and evolution over time of the at least one parameter of the life habit of the person is monitored during the monitoring, and the index of the person is updated based on the evolution over time of the at least one parameter of the life habit of the person.

7. The method according to claim 1 , wherein the index of the person is a function of at least one parameter of health of the person, and evolution over time of the at least one parameter of the health of the person is monitored during the monitoring, and the index of the person is updated based on the evolution over time of the at least one parameter of the health of the person.

8. The method according to claim 1 , wherein the index relates to a sleep index of the person.

9. The method according to claim 8 , wherein the index of the person is a function of at least one of the bed time, wake/up time, tonicity of the person before sleeping, and turquoise light exposure of the person.

10. The method according to claim 1 , wherein the index relates to an outdoor capital of the person.

11. The method according to claim 10 , wherein the index of the person is a function of at least one of the time spent outdoors, exposure time to ultraviolet and blue light.

12. The method according to claim 1 , wherein the index relates to a fitness index of the person.

13. The method according to claim 12 , wherein the index of the person is a function of at least one of activity level, number of steps, posture of the person while sitting.

14. A system for updating an index of a person comprising:

processing circuitry configured to

receive the index of the person defined as a function of at least one life parameter of the person,

mind

monitor the at least one life parameter of the person over time, and

process at the least one life parameter of the person to update the at least one index of the person based on evolution over time of the at least one life parameter of the person,

wherein the index of the person corresponds to a vision capital of the person, the vision capital providing an indication of eye health of the person and the at least one life parameter of the person is a visual behavior parameter relating to visual behavior of the person, the visual behavior parameter of the person relating to a visual effort of the person.

15. The system according to claim 14 , wherein the system further comprises a mounted sensing device configured to monitor the at least one life parameter of the person sensed by at least one sensor.
