Description

[0001] The invention relates to an ophthalmic system comprising at least one optical element, such as a spectacle lens, the control of changes in the functionality of which is improved.

[0002] Ophthalmic systems are known, such as frames comprising electrochromic lenses, the transmittance value of which can be automatically changed according to the brightness of the environment the user finds himself in. The electrochromic lenses are electrically connected to an autonomous control processor and one or more sensors adapted to measure light flux, the processor being adapted to control the transmittance value of the variable transmittance lens according to the measured light flux.

[0003] However, it is difficult to effectively control such an ophthalmic system solely based on the light flux measured by the sensors of the ophthalmic system. Indeed, the sensors integrated into the frame may not necessarily provide sufficiently accurate measurements, for example when the sensors are poorly positioned with respect to the light flux, thereby limiting the control performance of the transmittance of the lens. It may also prove difficult to integrate a large number of sensors into the same ophthalmic system to enhance the reliability of one or more measurements obtained and to optimize the control of the ophthalmic system.

[0004] Finally, the control of the functional change of the optical element may also depend on other data specific to the user of the ophthalmic system, such as their personal sensitivity to light or their activity (reading, sports, driving). The control may also depend on external items of information, such as geographical location or meteorological data (presence of near light sources, grazing sun, tunnel passage / exit, etc.), and data related to the environment in the vicinity of the user (e.g. the presence of a person speaking or a large group of people).

[0005] The present invention aims at least partially to solve the drawbacks set out above and more specifically to control the variation of the functionality of an optical element without the ophthalmic system having to have a large number of sensors, thereby providing improved visual comfort for the user.

[0006] Therefore, the present invention relates to a method for controlling an ophthalmic system, the ophthalmic system comprising:

[0058] at least one optical element,

[0059] at least one measuring sensor,

[0066] The invention will now be described with the aid of the accompanying drawings, in which:

[0067] - Figure 1 is a schematic diagram of an assembly including an ophthalmic system and an electronic device according to a first embodiment;

[0068] - Figure 2 yes Figure 1 Schematic diagram of the ophthalmic system;

[0069] - Figure 3 is a schematic diagram of an assembly including an ophthalmic system and a plurality of electronic devices according to a second embodiment; and

[0070] - Figure 4 is a schematic diagram of an assembly including a plurality of ophthalmic systems and a plurality of electronic devices according to a third embodiment.

[0071] It should be noted that in the drawings, structural elements and / or functional elements common to various embodiments may have the same reference numerals. Therefore, unless otherwise specified, such elements have the same structural characteristics, dimensional characteristics, and material characteristics.

[0072] For clarity, only elements useful for understanding the described embodiments have been shown and will be described in detail.

[0073] Figure 1 is a schematic diagram of an assembly comprising an ophthalmic system 1 and a communicating external electronic device 9. By "external" it is meant that the electronic device 9 is distinct from the ophthalmic system 1 or is external thereto.

[0074] The ophthalmic system 1 comprises at least one optical element 2. Figure 1 As shown, the system 1 comprises a frame 3, which has two temples 3a, 3b. Figure 1 In the embodiment of the present invention, the ophthalmic system 1 comprises two optical elements 2a, 2b mounted in a frame 3. Subsequently, the present invention is described with respect to a single optical element 2. However, it should be understood that the present invention may also be applicable to an ophthalmic system 1 comprising several optical elements 2, such as Figure 1 shown.

[0075] The optical element 2 may be any optical device intended to be placed in, on, near, substantially facing or upstream of a visual organ such as an eye, along the direction of light rays generated by a light source. In particular, the optical element 2 is an ophthalmic lens mounted on an ophthalmic system 1 intended for a person, such as a pair of glasses.

[0076] Such an optical element 2 may or may not have a corrective effect. For example, the optical element 2 may be opaque (sunglasses) or informative (information display).

[0077] The optical element 2 comprises a variable functionality.

[0078] According to one embodiment, the optical element 2 is a lens of the electro-active type. In this embodiment, the variation of the functionality associated with the lens consists in the modification of at least one characteristic of an electro-active unit comprised in the lens.

[0079] An "electroactive lens" is an optical device that has at least one characteristic that changes under the influence of an electrical and / or electromagnetic signal. Typically, a change in the amplitude of an electrical signal applied to an electroactive lens changes the function of the lens.

[0080] In one embodiment, the optical element 2 may be, for example, a lens whose transmittance is electrically controlled, with amplitude variation, hue variation (e.g., by means of liquid crystals), and / or active polarization. More particularly, the optical element 2 is an electrochromic lens, wherein the function associated with the optical element 2 includes the transmittance of the lens. For example, the function may relate to the switching on / off of the optical element 2, the level of transmittance, the range of minimum / maximum transmittance, the number and value of transmittance layers if a transmittance layer is used, and / or the transition speed between two transmittance layers.

[0081] However, the invention is not limited to electrochromic lenses and may also relate to other types of electroactive lenses, such as liquid crystal lenses («Liquid Crystal Displays—LCD»).

[0082] According to another embodiment, the optical element 2 is an informational lens, comprising, for example, a passive lens combined with a holographic mirror. A variation of the functionality of this optical element 2 thus enables the display of information on the lens destined for the user.

[0083] More generally, the optical element 2 may be any active device comprising a functional variation.

[0084] like Figure 2 As schematically shown, the ophthalmic system 1 comprises a processor 4 connected to the optical element 2 and capable of controlling changes in functions associated with the optical element 2 .

[0085] The ophthalmic system 1 further comprises a sensor 5 arranged on the frame 3 or directly at the height of the optical element 2. Figure 1 As shown, the sensor 5 is arranged, for example, at the height of the nose bridge of the spectacle frame 3 .

[0086] The sensor 5 may be an illumination sensor, such as a photodiode or an illumination microsensor (also referred to as an "ambient light sensor" ALS). The sensor 5 may thus measure the light flux received per unit surface area (in lux or Wm2). -2 As a variant, the sensor 5 can also measure other values ​​of the luminous flux, such as intensity, or visual brightness or photometric brightness. The sensor 5 can, for example, measure the luminous flux under visible light and / or ultraviolet light.

[0087] The sensor 5 may also be a light sensor adapted for measuring the polarization degree of light, in particular for activating a polarization cut-off function. The sensor 5 may also be adapted for measuring the visible and / or invisible luminescence spectrum for activating a wavelength selective cut-off function.

[0088] The sensor 5 is thus adapted to measure the ambient light flux reaching the ophthalmic system 1. "Ambient" refers to the light flux in which the ophthalmic system 1 is located. Thus, the ambient light flux varies with conditions external to the ophthalmic system 1, such as meteorological conditions when the ophthalmic system 1 is located outdoors, or room lighting when the ophthalmic system 1 is located indoors.

[0089] The measuring sensor 5 may also measure parameters other than the light flux and may therefore be:

[0090] - a proximity sensor that works, for example, by measuring the emission / reception time of electromagnetic waves. Proximity measurements can be made between the ophthalmic system 1 and its user, between the ophthalmic system 1 and an external electronic device, between the ophthalmic system 1 and another ophthalmic system, etc.;

[0091] - Position measurement (e.g. geolocation measurement) sensors. A geolocation measurement may correspond to at least one of the following: a geographic location (e.g. via longitude and latitude), a spatial location (e.g. a Galilean reference frame), a proximity measurement relative to another object, a proximity or presence measurement at a specific location (a cinema, a restaurant, a tourist attraction, etc.). Such sensors are typically GPS (“Global Positioning System”) electronic devices;

[0092] - an inclinometer for acquiring tilt measurements, making it possible, for example, to determine measurements of a user of the ophthalmic system 1 ;

[0093] - A gyroscope for obtaining gyroscope measurements;

[0094] - a distance meter for obtaining distance measurements;

[0095] - a manometer for obtaining pressure measurements;

[0096] - a thermometer for obtaining temperature measurements;

[0097] - an “eye tracker” device (device for tracking eye movements), said device being able to acquire measurements tracking the movements of at least one eye of a user of the ophthalmic system 1 ;

[0098] - a microphone for acquiring sound signals;

[0099] - a camera for acquiring a video signal, such as a plenoptic camera;

[0100] - a sensor measuring the luminous intensity in at least one band of the electromagnetic spectrum;

[0101] - Collection means capable of collecting electrical energy, for example via solar energy sensors (photovoltaic cells) or mechanical energy sensors (vibration sensors, for example on a human face), or collecting thermal energy, etc.

[0102] The ophthalmic system 1 may also include a plurality of sensors 5, in particular two sensors 5, for measuring the same value or different values. Subsequently, the present invention is described with respect to a single optical sensor 5. However, it should be understood that the present invention may also be applicable to an ophthalmic system 1 including a plurality of sensors 5.

[0103] The ophthalmic system 1 may comprise further elements, such as a battery 6, making it possible to supply energy to the electronic components of the ophthalmic system 1. The ophthalmic system 1 may also comprise a memory 7 adapted to store parameters or data related to the functioning of the optical element 2. Storing these data directly in the memory 7 of the ophthalmic system 1 makes it possible to prevent them from being lost, as might be the case if these data were stored on another electronic device.

[0104] The ophthalmic system 1 further comprises a communication interface 8. The communication interface 8 is connected (eg by a wired or wireless link) to the optical element 2. The communication interface 8 is adapted for sending / receiving data between the ophthalmic system 1 and an electronic device 9.

[0105] The electronic device 9 may be a mobile phone, a digital tablet, a connected watch, a desktop or laptop computer, a remote server accessible via, for example, the Internet, a terminal integrated into a motor vehicle or a GPS, a dedicated terminal for manufacturing and / or configuring ophthalmic lenses, a garment, a pair of shoes, a mask, an accessory connected or in a GPS. In general, the electronic device 9 may be any electronic device capable of being connected to the ophthalmic system 1.

[0106] The electronic device 9 may also comprise a sensor as described above with reference numeral 5 for the ophthalmic system 1. In particular, the electronic device 9 may also be another ophthalmic system as described above, such as a pair of glasses.

[0107] The link between the electronic device 9 and the ophthalmic system 1 may be wired, wireless, optical, induction-based, etc.

[0108] More specifically, the ophthalmic system 1 may be connected via a communication network C to the electronic device 9 .

[0109] Thus, for short-range radio links (typically less than 100 meters), the communication network C may be of Bluetooth (trademark) or ZigBee (trademark) type used at very low bit rates. The communication network C may also be of wifi type used at high bit rates or a network oriented towards home automation. For long-range radio links (typically greater than one kilometer), the communication network C may be of ZigFox (trademark), LORA (trademark) based on the LoRaWAN ("Long Range Wide Area Network") protocol, GSM ("Global System for Mobile Communications"), 3G or 4G type.

[0110] The communication network C may be a LiFi (trademark) network for short-range optical links (typically able to cover the interior of a room), or a QI network for very short-range magnetic inductive links.

[0111] Other protocols may be used, such as IP, Ethernet, TCP / UDP, the Internet, networks using universal asynchronous transmitter-receivers, for example of the UART (Universal Asynchronous Receiver Transmitter) type, networks relying on the http protocol (Hypertext Transfer Protocol), etc.

[0112] The electronic device 9 may also be connected to a data network D. "Data network" refers to any type of network that can provide data complementary to the data of the communication network C. In one embodiment, the data network D is different from the communication network C. Specifically, when the communication network C is a local area network (e.g., Bluetooth), the data network D may be, for example, a wide area network (e.g., the Internet via a 4G connection).

[0113] The following describes a method for controlling changes in functions associated with the optical element 2 according to a first embodiment of the present invention. Figure 1 According to this first embodiment, a single user of the ophthalmic system 1 is considered, for example a wearer of a pair of spectacles.

[0114] In a first step of the method, referred to as the measurement value acquisition step, measurement values ​​of the sensor 5 of the ophthalmic system 1 are acquired.

[0115] In a second step of the method, the acquired measured values ​​are sent to a communicating external electronic device 9. The measured values ​​are sent to the electronic device 9 via a communication network C in particular by a communication interface 8 of the ophthalmic system 1 .

[0116] During this second step, other data may also be sent, which are related to the optical element 2 and which may be used to determine the instructions for the change of the control function. These data may relate to the profile of the user, in particular their preferences related to their light sensitivity. These data may also relate to usage data of the ophthalmic system 1, such as the number of operating hours, the current consumption, statistics on the transmittance levels used, statistics on the dynamics of the transmittance changes, the charge level of the battery 6, etc. These data sent by the ophthalmic system 1 to the electronic device 9 are subsequently referred to as internal.

[0117] In a third step, called acquisition step, the electronic device 9 acquires one or more items of information in addition to the internal data.

[0118] The information items obtained are data previously stored in a memory (not shown) of the electronic device 9 or, if relevant, measured by sensors of the electronic device 9. The information items may also be data previously stored in a database 10 and sent to the electronic device 9 by a server 11 via a data network D. The information items obtained by the electronic device 9 are therefore referred to as external, in contrast to internal data originating from the ophthalmic system 1 of the user.

[0119] The one or more external information items obtained by the electronic device 9 include at least one element or a combination of elements from the following items:

[0120] - items of meteorological information (e.g. local data on pressure, hygrometry, temperature, sunshine, wind speed, rainfall / snowfall, etc.);

[0121] an item of geographical location information making it possible in particular to determine the activity of the user of the ophthalmic system 1 (for example, whether the user is in a restaurant or in a cinema);

[0122] - information items with timestamps;

[0123] - items of information relating to the environment of the user of the ophthalmic system 1 , for example regarding the presence of obstacles, specific places (eg tunnels) or other persons in the vicinity of the user of the ophthalmic system 1 ; and / or

[0124] - Information items relating to previously acquired measurement values ​​of the sensor and / or previously changed control values ​​of functions of the ophthalmic system 1 .

[0125] In a fourth step of the method, called selection or convergence step, at least one information item obtained by the electronic device 9 is selected. In particular, the selected information item preferably corresponds to the position of one or more measurements acquired by the sensor 5 of the ophthalmic system 1 and / or to the time period corresponding to said position. It is thus possible to associate the transmitted internal data ophthalmic system 1 with external information items corresponding to the same or close time / position measurements. If necessary, several information items can also be selected.

[0126] In a fifth step, instructions are determined based at least on the measurement values ​​acquired by the sensor and the selected information item.

[0127] According to one embodiment, the determination of the instructions is performed by the processor 4 of the ophthalmic system 1. According to this embodiment, the selected information item is sent from the electronic device 9 to the processor 4 of the ophthalmic system 1 before the instructions are determined based on the measurements acquired by the sensor 5 and the selected information item.

[0128] According to another preferred embodiment, the determination of the instructions is performed by a processor (not represented) of the electronic device 9. In fact, the electronic device 9 may have a greater computing power than the ophthalmic system 1 and may therefore more quickly determine the instructions for controlling the changes in the functions of the optical element 2. This also makes it possible to limit the consumption of the energy stored by the battery 6 of the ophthalmic system 1 and therefore increase the duration of the autonomy of the ophthalmic system 1.

[0129] According to one embodiment, the determination of the instruction based on the measurements acquired by the sensor 5 and the selected information items is performed based on a predetermined model of the functionality of the optical element 2. The model of functionality can be of any type, in particular based on fuzzy logic or modal logic. Thus, the model of functionality comprises at least the measurements acquired by the sensor 5 and the selected information items as input data. The model may also take into account other input parameters, such as other internal data related to the ophthalmic system 1 or the user.

[0130] By way of purely illustrative example, the model may provide that when the user is in a certain place, for example at his workbench, the optical element 2 must allow all the light to pass, regardless of the light flux measured by the sensor 5 of the ophthalmic system 1. The model then determines the instructions that are intended to be sent to the optical element 2 in this sense.

[0131] According to another example, the model may provide that when the user is driving (the electronic device 9 is, for example, an onboard computer of a car), the optical element 2 must always be opaque so that the user enjoys better visibility throughout the journey. The model then determines instructions for controlling a constant reduced transmittance value of the optical element 2 as long as the item of information obtained by the electronic device 9 indicates that the user is in the car or that they are driving the car.

[0132] According to yet another example, when the user is in the presence of a person who is speaking, the model can reduce the transmittance of the user's optical element 2. The model then determines the reduced transmittance level based on the luminous intensity measured by the sensor 5 in which the user himself is located and based on the information item obtained by the electronic means 9 indicating the presence of other people around the user.

[0133] In a sixth step, instructions are sent to the processor 4 of the ophthalmic system 1 , in particular via the communication interface 8 of the ophthalmic system 1 (if relevant).

[0134] Finally, in a seventh step, the processor 4 of the ophthalmic system 1 executes the instructions to control the change of the functions associated with the optical element 2 .

[0135] Thus, the functions of the optical element 2 can be controlled in an automatic manner. "Automatically" means that no physical interaction with the user of the ophthalmic system is necessary in order to control the functions of the optical element 2. In particular, the ophthalmic system 1 preferably does not comprise any means enabling interaction with the user of the ophthalmic system 1, such as a touch-sensitive interface or buttons.

[0136] However, in an optional eighth step, if the user is not satisfied with the change in the functionality of the optical element 2, they can modify the functionality of the ophthalmic system from the human-machine interface. According to this eighth step, the model can be adapted by training according to the functional modifications performed by the user. The model of the functionality of the optical element can thus be modified and gradually optimized to obtain better comfort and preferred control settings for the user of the ophthalmic system 1.

[0137] According to one embodiment, all data necessary for the functions and modification of the control model may be stored in the memory 7 of the ophthalmic system 1. Thus, the ophthalmic system 1 may enable access to these data from the human-machine interface of the electronic device. Accessing the human-machine interface from the electronic device may also enable performing updates, troubleshooting the ophthalmic system 1, saving user profiles, etc.

[0138] Once sent to the electronic device 9, the internal data, in particular the measured values ​​of the sensor 5, and the external information items obtained by the electronic device can be time-stamped and then stored in a memory (not represented) of the electronic device 9. As a variant, the internal data and the external information items are stored in an external database 10 adapted to communicate with the electronic device 9 via a data network D.

[0139] In the same way, internal data sent by the ophthalmic system, in particular the measurements of the sensor 5 , and external information items acquired by the electronic device 9 can be geolocated and then stored in a memory of the electronic device 9 or in a database D.

[0140] These previously acquired internal data and external information items related to the history of use of the ophthalmic system 1 can therefore be reused later. Specifically, they can enable the saving of certain data related to the user, such as the weather history in the user's area, the activities performed by the user, their past locations, etc.

[0141] It is also possible to track the history of certain data related to the optical element 2, such as the opening / closing rate of the optical element 2, its transmittance, or the displayed image, to know whether the user is in the reading stage.

[0142] Thus, previously acquired and then stored internal data and external information items can be used in a way that improves the user's comfort, to allow tracking of information items related to the user (e.g., exposure rate under UV, or consumption of the ophthalmic system 1), to monitor potential malfunctions of the ophthalmic system 1 (consumption of the ophthalmic system 1, difficulties in achieving the desired function related to the optical element 2, etc.). Thanks to the transmission of these internal data and external information items, the tracking and / or commanding of the ophthalmic system 1 can be performed in particular remotely.

[0143] The following describes the Figure 3 and Figure 4 The methods according to the second and third embodiments of the present invention are shown.

[0144] According to a second embodiment, the assembly comprises an ophthalmic system 1 and a plurality of communicating external electronic devices 9a, 9b, 9c. According to this second embodiment, the ophthalmic system can send and / or receive external information items originating from the various electronic devices 9a, 9b, 9c. For example, each electronic device 9a, 9b, 9c can send the external information items necessary for determining the control instructions for the functions related to the optical element 2 through the same communication network C or several different networks Ca, Cb, Cc.

[0145] According to a third embodiment, the assembly comprises a plurality of ophthalmic systems 1a, 1b, 1c and a plurality of communicating external electronic devices 9a, 9b, 9c. According to this third embodiment, the ophthalmic system 1a can send and / or receive external information items originating from the various electronic devices 9a, 9b, 9c and the other ophthalmic systems 1b, 1c.

[0146] Thus, users of other ophthalmic systems can send data enabling control of changes in functions associated with the optical element 2 to be determined.

[0147] For example, a group of wearers distributed in a geographical area can individually measure data related to the brightness of the environment. Based on these measurements and the items of geographical and meteorological information obtained by the electronic means 9a, 9b, 9c, it may be possible to foresee an upcoming change in the brightness of the user, for example due to the passage of a cloud, and which has already been measured by some other wearers. In the same way, it may be possible to foresee the presence of an upcoming obstacle, such as a passage under a tunnel.

[0148] Obviously, the present invention is not limited to the embodiments described above but is provided only by way of example. The present invention includes various modifications, alternative forms and other variations that can be conceived by those skilled in the art in the context of the present invention, in particular any combination of the above-mentioned various operating modes that can be adopted individually or in combination.
