Orthokeratology contact lens for treating myopia

An orthokeratology contact lens for controlling myopia comprising:

• an incurved anterior side;
• and
• a posterior side comprising a curvature, the posterior side configured to be applied to an eye comprising a retina and a cornea with a corneal epithelium, wherein the posterior side defines:
• a central area adapted to coincide with an optical or visual area of the eye and conform a surface of the cornea by exerting a positive hydrodynamic pressure on the corneal epithelium;
• and
• a peripheral area concentric with the central area, the peripheral area comprising an annular portion defining a teardrops accumulation area configured to exert a negative hydrodynamic pressure on the surface of the cornea by conforming the surface of the cornea and creating a positive power amp-up ring, wherein the annular portion includes:
• a first segment which extends concentrically with respect to the central area, along a radius defined with respect to a geometric center which defines the curvature of the posterior side, towards the incurved anterior side up to an annular border line;
• and
• a second segment which extends from the annular border line and concentrically with respect to the central area, the second segment configured to extend up to a point of contact with the surface of the cornea,
• wherein the first segment and the second segment form a broken line such that the annular border line defines a ridge for the teardrops accumulation area having a teardrops height.
