Disclosed are light glare reducing apparatuses and related methods. A light glare reducing apparatus includes a first polarized body, a second polarized body, and a movable coupling that attaches the second polarized body to the first polarized body with the second polarized body at least partially overlapping the first polarized body. The first polarized body includes a first polarized material that is optically polarized in a first direction relative to the first polarized body. The second polarized body includes a second polarized material that is optically polarized in a second direction relative to the second polarized body. The movable coupling is configured to enable the second polarized body to move relative to the first polarized body to change an angle of the second direction relative to the first direction.

A system for providing variable opacity includes a polarization assembly disposed at a vehicle. The polarization assembly includes a first panel having a plurality of first polarizing elements, and a second panel having a plurality of second polarizing elements, the first panel and the second panel overlapping in a path of light incident on the vehicle. The system also includes an actuation device configured to linearly translate the first panel relative to the second panel between a first position in which the polarization assembly is transparent to the light and a second position in which the polarization assembly at least partially blocks the light.

A filming apparatus installed in an interior of a vehicle to film images reflected on a windshield glass is provided. The apparatus may include a polarizing filter provided on a front surface or a rear surface of a lens, or a front surface of an image sensor, a transmission factor of the polarizing filter being lower at a first point than a second point, where reflected light is input from a portion of the windshield glass at the first point and a shimmering occurs at the first point.

A system such as a vehicle may have window that exhibit adjustable transparency. The windows may include liquid crystal devices and polymer dispersed liquid crystal devices that exhibit adjustable amounts of light transmission and haze. An optical property of a window such as window transparency may be modulated using an alternating-current modulation waveform. Modulation of the transparency of the window may be synchronized with modulated light output from a light source. The light source may be located inside the vehicle or may be located outside of the vehicle. By synchronizing the modulation of the transparency of the window with the light source output, privacy may be enhanced or glare may be reduced.

A driver for an electrically dynamic structure may store and release energy during polarity cycling to improve the energy efficiency of operation. In some examples, the driver includes an energy storage element. In operation, the driver can charge an electrically controllable optically active material to a first operating voltage at a first polarity and subsequently discharge the optically active material during polarity reversal. The driver may store energy released from the optically active material during discharging and subsequently release the energy to charge the optically active material to a second operating voltage at a second polarity different than the first polarity.

A visor assembly for an automobile includes an outer perimeter. The visor assembly further includes an electrochromic device configured to switch between a transparent state and a darkened state. The electrochromic device includes a first substrate defining a first element surface and a second element surface, a second substrate spaced away from the first substrate and defining a third element surface and a fourth element surface, and an electroactive medium positioned between the first and second substrates. The visor assembly further includes a liquid-crystal device configured to switch between a transparent state and a reflective state and a reflective polarizer positioned between the electrochromic device and the liquid-crystal device.
