A system includes glasses for executing a process to correct the alignment of an eye if a misalignment condition is detected. The glasses include lens that change opacity as instructed by a processor. The system determines that an eye is not aligned correctly based on data captured by one or more sensors in the glasses. Data is captured periodically and compared to a baseline set of data. If a deviation is detected, then the appropriate lens is turned “ON” to shade the aligned eye, thereby forcing the misaligned eye to properly align itself.

This application relates to an electrochromic lens. In one aspect, the lens includes a substrate including a first surface and a second surface opposite to the first surface, a first electrode layer disposed on the first surface of the substrate, and a second electrode layer disposed on the first electrode layer. The lens may also include an electrochromic layer disposed between the first electrode layer and the second electrode layer, and adjusting transmittance of light incident on the second surface of the substrate. The lens may further include a first conductor electrically connected to the first electrode layer, and having higher conductivity than at least one of the first electrode layer or the second electrode layer. The lens may further include a second conductor electrically connected to the second electrode layer, and having higher conductivity than at least one of the first electrode layer or the second electrode layer.

Provided is an electrochromic element including: a support; an electrochromic layer over the support; an electrolyte layer over the support; and a sealant resin layer in contact with the electrochromic layer at longitudinal ends of the electrochromic layer in a layer lamination direction, wherein the electrochromic layer contains a polymerized product of an oxidatively color-developable electrochromic composition containing a radical-polymerizable compound, and the sealant resin layer contains a thermosetting material.

Described herein are examples of smart helmet modules that can be affixed to conventional welding helmets. In some examples, a smart helmet module may include one or more sensors configured to detect if/when welding is occurring, and/or whether a welding helmet is being worn in an up or down position, or not at all. In some examples, a smart helmet module may include one or more helmet devices configured to automatically activate or deactivate based on whether welding is taking place and/or the welding helmet is being worn up, down, or not at all.

Eyewear dynamically adjusts viewing effects to match the wearer, the object or scene being viewed (luminance, color prominence, glare, visual blur/noise), other conditions: sensory parameters (gaze direction, focal length, eye gestures, other eye activity, other senses, wearer inputs), medical conditions, wearer location, environmental parameters, wearer activity, use by the wearer, the wearer's field of view. The eyewear can adjust visual features presented to the wearer, such as changes in refraction, polarization/shading, color, prismatic angles/functions, 3D displays. Eyewear can be tailored to form factor: glasses, contacts, RID, IOL, facemask/helmet, vehicles, windows, screens, scopes, AR/VR devices, nerve sensors, external devices. Eyewear can adjust refraction, polarization/shading, color filtering/injection, false coloring, color change; prismatic angles/functions. Eyewear can respond to wearer activity: police, military, firefighter, emergency responder, search and rescue, vehicle operation, sporting/theme-park events, viewing advertising/storefronts, conversation. Hybrid optimization of eyewear can be personalized to users.

The invention relates to an optical filter comprising: at least one optically transparent liquid-crystal shutter, the shutter having a polarization voltage ULCD that marks a threshold between two polarization states, and being designed to switch between at least two opacities OP1 and OP2, OP2 being strictly higher than OP1, when it receives a voltage that is above or below, respectively, the polarization voltage ULCD; and an electronic system comprising: an electronic module for controlling the liquid-crystal shutter, designed to control the voltage applied to the liquid crystal shutter; a photosensitive sensor, designed to deliver, to the electronic control module, a continuous voltage Ucs that varies depending on the luminous intensity that it receives, the photosensitive sensor being the only power supply of the electronic control module and the liquid-crystal shutter, the optical filter being characterized in that, if the photosensitive sensor receives a luminous intensity below a dazzle threshold le, the liquid-crystal shutter has an opacity OP1, and in that the electronic control module is designed, when the photosensitive sensor receives a luminous intensity above the dazzle threshold le, to deliver, to the liquid-crystal shutter, a continuous voltage Ue that is strictly above the polarization voltage ULCD of the shutter, so that the latter switches from opacity OP1 to opacity OP2.

Provided are a smart window, a sliding smart window, a smart window for a vehicle, a sun visor for a vehicle, a smart window device, and a head-mounted smart window device which have maximized user convenience.

An electrically controlled spectacle includes a spectacle frame and optoelectronic lenses housed in the frame. The lenses include a left lens and a right lens, each of the optoelectrical lenses having a plurality of states, wherein the state of the left lens is independent of the state of the right lens. The electrically controlled spectacle also includes a control unit housed in the frame, the control unit being adapted to control the state of each of the lenses independently.

A display for virtual reality is discussed, which is capable of alleviating a screen-door effect, thereby improving its image quality. In the display for virtual reality, a light diffusion member, which diffuses light emitted from a light-transmitting area of a display panel to a light-blocking area of the display panel, is interposed between the display panel and an optical lens, whereby a user who views an image displayed on the display panel at a very close position does not perceive the light-blocking area, which improves the image quality of the display.

The invention is based on a protection device, in particular a glare-protection device, with at least one optical glare-protection filter comprising a nose cut-out, with at least one sensor unit, which is provided to capture a work state and to control, depending on this, a permeability of the glare-protection filter, with at least one shield unit, in which the at least one glare-protection filter is fixedly accommodated, and with at least one head-fastening unit for a fastening to a user's head. It is proposed that the protection device comprises at least one adjusting unit, by which a position of the at least one shield unit is implemented in such a way that it is movable with respect to the at least one head-fastening unit in a defined manner.
