Abstract

The invention relates to the field of management systems and methods of an active device and more particularly, with said active device being an active ophthalmic lens, to a management system and method which allow a total or sufficient protection by taking into account the luminous environment of the wearer while avoiding some effects relative to permanent light filtering. According to a particular embodiment of the invention, there is also provided a monitoring of the wearer's health via active, regulated and continuous control of the active device, this control being performed for instance by a health professional via a remote monitoring system.

First claim

The invention claimed is:

1. A management system of an active device comprising:
an active device comprising at least one light filter for filtering at least one among a first range and a second range of a light spectrum;
a first sensor arranged to measure data relating to light within said first range and reaching, or transmitted through, the active device;
a second sensor arranged to measure data relating to light within said second range and reaching, or transmitted through, the active device;
control circuitry configured to activate said light filter and control at least one of:
the filtering of light within said first range according to data measured by at least one of the first and second sensors, and
the filtering of light within said second range according to data measured by at least one of the first and second sensors; and

a memory configured to store said measured data, the storing correlating at least said measured data relating to light within the first range with said measured data relating to light within the second range.

2. The management system according to claim 1 , wherein said first range of the light spectrum comprises blue light corresponding to light with wavelengths between 400 and 460 nm and said second range of the light spectrum comprises chronobiological blue light.

3. The management system according to claim 1 , wherein the circuitry is further configured to control transmitting said measured data to a remote monitoring system.

4. The management system according to claim 1 , wherein the control circuitry is further configured to
control storage of threshold values determined at least on a basis of information about a person situated in a vicinity of the active device and logically related to said first and second ranges of the light spectrum, and
compare data measured by the active device with corresponding threshold values, in order to consequently control the active device.

5. The management system according to claim 4 ,
wherein said threshold values comprise phototoxicity and chronobiological threshold values.

6. The management system according to claim 5 , wherein the active device is an active ophthalmic lens, the management system further comprising at least one of:
a chronobiological marker sensor for measuring data relating to chronobiological characteristics of a wearer of the active ophthalmic lens;
an actimetry sensor for measuring data relating to an activity of the wearer of the active ophthalmic lens; and
a positioning system for measuring data relating to a location of the wearer of the active ophthalmic lens, in order for the control circuitry to take into account at least one of supplementary measured data for controlling the active ophthalmic lens,
the supplementary measured data comprising data relating to the chronobiological characteristics of the wearer of the active ophthalmic lens, data relating to the activity of the wearer of the active ophthalmic lens, and data relating to the location of the wearer of the active ophthalmic lens.

7. The management system according to claim 6 ,
wherein, with said threshold values further depending on at least one among said supplementary measured data, wherein each of the chronobiological marker sensor and the actimetry sensor is arranged to transmit the supplementary measured data measured by said sensor to the control circuitry, and wherein said control circuitry is further configured to determine said threshold values by taking into account for said supplementary measured data.

8. The management system of claim 1 , wherein said management system is a component of an eyewear.

9. A management method of an active device comprising:
filtering, with an active device comprising at least one light filter, at least one among a first range and a second range of a light spectrum,
measuring data relating to light within said first range and reaching, or transmitted through, the active device, with a first sensor of the active device;
measuring data relating to light within said second range and reaching, or transmitted through, the active device, with a second sensor of the active device;
activating said light filter, with control circuitry of the active device;
controlling, with the control circuitry, at least one of:
the filtering of light within said first range according to data measured by at least one of the first and second sensors, and
the filtering of light within said second range according to data measured by at least one of the first and second sensors; and

storing the measured data, in a memory arranged thereto, by correlating at least said measured data relating to light within the first range with said measured data relating to light within the second range.

10. The management method according to claim 9 , wherein said first range of the light spectrum comprises blue light corresponding to light with wavelengths between 400 and 460 nm and said second range of the light spectrum comprises chronobiological blue light.

11. The management method according to claim 9 , further comprising:
transmitting said measured data measured by the active device to a remote monitoring system, with the storage being designed therefor.

12. The management method of claim 9 , further comprising, with the control circuitry, processing and storing threshold values determined at least on a basis of information about a person situated in a vicinity of the active device and logically related to said first and second ranges of the light spectrum, and
wherein controlling the active device comprises: comparing data measured by the active device with corresponding threshold values to consequently control the active device.

13. The management method according to claim 12 , wherein said threshold values comprise phototoxicity and chronobiological threshold values.

14. The management method according to claim 13 , wherein the active device is an active ophthalmic lens, the method further comprising:
measuring data relating to chronobiological characteristics of a wearer of the active ophthalmic lens, with a chronobiological marker sensor of the active device;
measuring data relating to an activity of the wearer of the active ophthalmic lens with an actimetry sensor of the active device; and
measuring data relating to a location of the wearer of the active ophthalmic lens with a positioning system,
in order for the control unit to take into account at least one of supplementary measured data for controlling the active ophthalmic lens,
wherein the supplementary measured data comprising data relating to the chronobiological characteristics of the wearer of the active ophthalmic lens, data relating to the activity of the wearer of the active ophthalmic lens, and data relating to the location of the wearer of the active ophthalmic lens.

15. The management method according to claim 14 , further comprising determining said threshold values based on at least one among said supplementary measured data, said supplementary measured data having been transmitted by each of the chronobiological marker sensor and the actimetry sensor.

16. A non-transitory computer readable storage medium having instructions recorded thereon, which when executed by a processor of a management system, cause the processor to perform operations comprising:
filtering, with an active device of the management system having at least one light filter, at least one among a first range and a second range of a light spectrum,
measuring data relating to light within said first range and reaching, or transmitted through, the active device
