  • CONTACT LENS
    Publication number: 20250110353
    Abstract: Contact lenses include a toric lens body. The toric lens body has radii extending outward from a center along a radial direction. Cross sections of the toric lens body are defined by the radii and the toric lens body in a thickness direction. An area “A” of the cross section is presented by a formula (I): A=P?f(?). In formula (I), ? is an azimuth angle, 0°???360°, f(?) is a polynomial, and 0.5?P?7.
