  • Method for corrective lens and corrective lens
    Patent number: 11131868
    Abstract: A corrective lens that can improve contrast sensitivity in a dark place, for example, at night is provided. When an axis in the anteroposterior direction passing through the geometric center of a lens is defined as the z-axis and a direction extending to the rear side of the lens is defined as the positive direction of the z-axis, a focal depth extension component represented by Ar3 (where r is the distance from the z-axis and A is a constant) is added to the z-coordinate value of a refractive surface determined based on a prescription power to increase the focal depth. The focal depth that decreases (shallows) in a dark place is increased to facilitate focusing on a target object located in front of or behind the original focal point. This can improve contrast sensitivity in a dark place.

  • Beam steering devices
    Patent number: 11126061
    Abstract: A beam steering device includes a substrate with a first refractive index that defines a cavity, an electroactive material in the cavity that has a variable refractive index, and two sets of opposing overlays. The overlays in one set of opposing overlays are parallel to each other, while the overlays in the other set are tilted with respect to each other. This allows one or more electric fields between the overlays to be used to align the electroactive material in two different directions to change its refractive index, allowing for a faster speed of beam steering through refraction than conventional approaches.
