A sunglass using a transparent, pixelated, liquid crystal (LC) two-dimensional array, or functionally equivalent technology, in possible combination with optical materials to selectively attenuate or block the Sun or its reflection from the field of view (FOV) of the person wearing the glasses is disclosed. An imaging camera located within the sunglasses detects the Sun, with software determining its position via centroiding algorithms. The Solar position is then translated, and, if necessary, rotated, scaled and skewed for the appropriate pixels in the left and right lens of the sunglass, where left eye and right eye “circles” are created to block or attenuate the Sun's image from the person wearing the glasses. Additionally, the sunglass lens will have protection against the Sun's ultra-violet (UV) rays. The internal power source may be either replaceable, or charged by solar or standard methods.

Embodiments may provide a first device that comprises eyeglasses, where the eyeglasses may further include a lens housing, a first temple and a second temple coupled to the lens housing, and a first and a second lens supported by the lens housing. The first device may further include a façade that covers the lens housing. The first device may further comprise an electronic component and at least one conductive path may be provided from the electronic component to the first lens having a portion that runs through the lens housing.

The present invention relates to a group of novel electrochromic materials. More specifically, it relates to electrochromic materials based on either single or two-core viologen systems and the use of these viologen systems as a variable transmittance medium for the manufacture of an optical article, such as an ophthalmic lens.

The present invention relates to an electrochromic composition comprising at least one reducing compound and at least two oxidizing compounds, said at least two oxidizing compounds having similar oxydo-reduction potentials. More specifically, said at least two oxidizing compounds are selected from viologen derivatives. Said composition can be used as a variable transmittance medium for the manufacture of an optical article, such as an ophthalmic lens.

In one example an automatic false pupil contact lens comprises a body formed from an optically translucent material and a coating on the body formed from at least one of a photochromatic material or an electrochromatic material that, in response to an input, is to change between a first state in which the coating is optically translucent and a second state in which the coating is optically opaque in response to an input. Other examples may be described.

A head mounted display (HMD) includes a display device that uses a black duty insertion mode. The display device includes a liquid crystal (LC) panel, a back light unit (BLU), and a data driver. In the black duty insertion mode, the BLU emits light during a portion of a frame period and does not emit light during a remaining portion of the frame period. The data driver writes data to the LC panel such that liquid crystal material in the LC panel transitions during the frame period including the portion of the frame period that the BLU emits light. The portion of the frame period the BLU emits light is less than half of the frame period and may be 20% or less of the frame period.

The invention is based on a sun protection device, in particular sun spectacles, with at least one optical sun protection filter (12) comprising at least one liquid-crystal cell (14, 14′), with at least one sensor unit (16) configured for capturing a solar irradiation, and with at least one control and/or regulation unit (18), which is configured for controlling and/or regulating a permeability of the optical sun protection filter (12) depending on a solar irradiation.

It is proposed that the control and/or regulation unit (18) is in at least one operating state configured for controlling the at least one liquid-crystal cell (14, 14′) of the optical sun protection filter (12) for generating a permeability gradient (20), which is defined for a user (31) and features at least two differing permeabilities.

Improved wearable optics is disclosed. The wearable optics comprises a frame member and a lens. The wearable optics also includes circuitry within the frame member for enhancing the use of the wearable optics. A system and method in accordance with the present invention is directed to a variety of ways to enhance the use of eyeglasses. They are: (1) media focals, that is, utilizing the wearable optics for its intended purpose and enhancing that use by using imaging techniques to improve the vision of the user; (2) telecommunications enhancements that allow the eyeglasses to be integrated with telecommunication devices such as cell phones or the like; and (3) entertainment enhancements that allow the wearable optics to be integrated with devices such as MP3 players, radios, or the like.

The present disclosure provides an elastic electronic circuit adapted to provide three dimensional elasticity while conforming to the curved or angled structures of a swellable medical device, such as a hydrogel or silicone hydrogel contact lens. The elastic electronic circuit can include a first pattern for flexibility in a first dimension, a second pattern for flexibility in a second dimension, and a third pattern for flexibility in a third dimension. Alternatively, the elastic circuit can include a first pattern for flexibility in a first dimension and a second pattern for flexibility in a second dimension. The resulting three-dimensional elasticity enables the use of electronic circuits on soft contact lenses, where manufacture and use will cause the lenses and circuits to swell and shrink. Furthermore, the electronic circuit will not distort the vision correction of the contact lens or otherwise cause discomfort or other negative side effects.
