Abstract: A varifocal liquid lens includes a body filled with two different fluids separated by an interface of a variable curvature across a clear aperture of the varifocal liquid lens. At least one of the first or second fluids is birefringent, such that a refractive index difference between the first and second fluids and resulting optical power of the varifocal liquid lens is dependent on polarization of impinging light. At a first light polarization, the first and second fluids may be matched in refractive index, while at a second, orthogonal light polarization, the first and second fluids may be mismatched in refractive index, whereby the first interface between the first and second fluids may have a variable, non-zero optical power for the second polarization while having a substantially non-variable, zero optical power for the first polarization of light.

Abstract: An optical assembly is configured to receive visible scene light at the backside of the optical assembly and to direct the visible scene light on an optical path toward the eyeward side. The optical assembly includes a dimming element disposed on the optical path, where the dimming element includes a photochromic material that is configured to darken in response to exposure to a range of light wavelengths. A display layer is disposed on the optical path between the eyeward side of the optical assembly and the dimming element. The display layer is configured to direct visible display light toward the eyeward side and also to direct activation light to the dimming element, where the activation light is within the range of light wavelengths to activate a darkening of the photochromic material to dim the visible scene light.

Abstract: An optical assembly is configured to receive visible scene light at the backside of the optical assembly and to direct the visible scene light on an optical path toward the eyeward side. The optical assembly includes a dimming element disposed on the optical path, wherein the dimming element includes a photochromic material that is configured to darken in response to exposure to a range of light wavelengths. An illuminator, coupled to an edge of the dimming element, is configured to selectively emit an activation light within the range of light wavelengths to activate a darkening of the photochromic material to dim the visible scene light.
