ORTHOKERATOLOGY CONTACT LENS FOR TREATING MYOPIA

摘要

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.
