  • Patent number: 11454825
    Abstract: An orthokeratology contact lens for controlling myopia includes a curved front side and a back side intended to be applied to the eye. the back side defines a central area designed to align with the optical area of the eye, and a peripheral area, concentric to the central area, which includes an annular portion defining a tear accumulation area. The annular portion includes a first segment, which extends concentrically in relation to the central area, up to an annular limit line, and a second segment which extends from the annular limit line concentrically in relation to the central area, configured to extend up to the cornea. The first segment and the second segment form a broken line such that the annular limit line defines a peak with the height of a tear.

  • Patent number: 8162476
    Abstract: A contact lens includes at least two focal lengths, a single lower bearing surface capable of allowing the lens to be translated relative to an eye, and an area placed in the lower portion of the lens, the area having an outer face connected to a remainder of the outer face of the lens via a recess and the area having an inner face indistinguishable from the rest of an inner face of the lens, where the recess defines the lower bearing surface, and where the area is thin with an average thickness of the same order of magnitude as a thickness of an upper edge of said lens.
