Provided is an image display device for a vehicle that can make an image suitably visible by a simple structure even if the position of the driver's eyes changes. An image display device 100 for a vehicle is provided with: an image display unit 2 that has a light source and a display element and outputs image light; a mirror 3 that reflects the image light output by the image display unit 2 towarda windshield 7; a mirror drive unit 4 that changes the angle and position of the mirror 3; and a control unit 10 that determines amounts of change in the angle and position of the mirror and controlsthe mirror drive unit 4. The control unit 10 makes determinations of the amount of change for the angle and position of the mirror in association with each other such that the image is visible even if the position of the driver's eyes 8 changes and the display state of the image with respect to the driver does not change.

The present invention discloses a translating multifocal contact lens including one or both of multiple Optic Zones and a lower-lid contact surface, and method steps and apparatus for implementing the same. In preferred embodiments, a translating multifocal lens may be Free-formed comprising a lower-lid contact surface capable of limiting the amount of translation of a lens across a surface of an eye when an eye changes from one Optic Zone to another.

The invention discloses a mobile terminal and a method for controlling use of the mobile terminal. The mobile terminal provided by the invention comprises an eyeball tracking module, a device operation monitoring module, a reminding module and a device unlocking module, wherein the eyeball tracking module acquires an eye change feature of a mobile terminal user to obtain time data of using the mobile terminal, and transmits the time data to the device operation monitoring module; the device operation monitoring module receives the time data sent by the eyeball tracking module, performs statistics and analysis on time data of watching a screen of the mobile terminal by the eyes of the user, and decides whether prompt information is transmitted to the reminding module or not according to logic judgment; the reminding module locks the mobile terminal according to a judgment result sent by the device operation monitoring module and sends locking information to the device unlocking module; and the device unlocking module presets operation, and the user finishes the operation according to a prompt of the device unlocking module. According to the mobile terminal and the method, the problem of harm caused by overuse of the mobile terminal for a long time by the user separately is solved and the user is guided to correctly use the mobile terminal.

Disclosed is a dynamic lighting method, which includes a power supply output module of a dynamic lighting device outputs a first power supply signal according to a lighting control signal, electric parameters of the first power supply signal include one or more groups of dynamically changed electrical parameters, one or multiple lighting parts of the dynamic lighting device generate a dynamically changed light signal under driving of the first power supply signal, so that the dynamic lighting device outputs a light of dynamic illumination, a change rate of illumination of the light is not more than 0.02 during any time period of 0.1 second, and a ratio of the minimum and maximum values of the illumination of the light outputted by the dynamic lighting device is not more than 50%. The lighting method will result that the physiological structures of the eyes change with change of the light accordingly to overcome the defect that the user easily feels visual fatigue.

An intraocular lens provided for implantation into an eye, includes a lens body having a central region, haptics for holding the intraocular lens in place within the eye after implantation, and an activatable zone outside the central region. After implantation of the intraocular lens into the eye, the lens body is deformed in the central region and / or at least one of the position, the rotation or the tilt of the intraocular lens within the eye changes upon irradiating only the activatable zone with laser radiation.

The present invention provides a display device. The display device includes a display panel, a transparent substrate, a switch array, a tracker and a processor. The display panel includes pixels arranged in an array; the transparent substrate is arranged in the light emitting direction of the display panel; The side of the substrate away from the display panel includes multiple switches, each switch corresponds to at least one pixel on the display panel, and the switch is used to open or close the light channel of the pixel; the tracker is used to capture the position coordinates of the observer's eyes and determine the position of the eyes. position; the processor is used to determine the reference line for stereoscopic display according to the coordinates of the eyes, control the target switch on the reference line to open the light channel, and control the target pixels on the line between the eyes and the target switch to display the stereoscopic picture. The present invention controls the target switch on the reference line to open the light exit channel according to the positions of the eyes of the observer, and when the positions of the eyes change, the corresponding lit pixels also change accordingly, thereby increasing the viewing angle of the display device.

The present invention discloses a translating multifocal contact lens including one or more of multiple Optic Zones, a lower-lid contact surface, and an under-lid support structure and method steps and apparatus for implementing the same. In preferred embodiments, a translating multifocal lens with at least a portion of one surface may be Free-formed comprising one or both of a lower-lid contact surface and an under-lid support structure capable of limiting the amount of translation of a lens across a surface of an eye when an eye changes from one Optic Zone to another.

The invention belongs to the technical field of automobiles, and discloses a driving light warning method, device, equipment and storage medium. The method includes acquiring the light intensity collected by the light intensity collection sensor, and comparing the light intensity with a preset light intensity threshold; when the light intensity is greater than the preset light intensity threshold, acquiring the driver's eye change information; When the change information meets the preset conditions, the high beam warning system of the vehicle is turned on for light warning. Because the present invention obtains the driver's eye change information when the light intensity is greater than the preset light intensity threshold, and turns on the high beam warning system of the vehicle for light warning when the eye change information meets the preset conditions. Compared with the existing method of whistle warning when the light intensity reaches the preset threshold, the above method of the present invention more accurately identifies whether the change of the light intensity affects the driving of the driver, and then turns on the light warning, which improves the warning. Efficiency to avoid warnings due to misjudgments.
