Contact lenses

Abstract

The present invention discloses a contact lens comprising a first region, a second region, and a pattern. In a top view of the contact lens, the pattern is non-mirror-symmetrical on both sides of a predetermined axis passing through the center of the contact lens. In cross-sectional planes of the contact lens at different azimuthal angles, the sum of the first cross-sectional area corresponding to the first region, and the second cross-sectional region corresponding to the second region is defined as the sum of cross-sectional areas, and the ratio of the second cross-sectional area to the sum of the cross-sectional areas varies with the azimuthal angle, ensuring that, when the contact lens is worn, the pattern aligns with the intended position relative to the user's eye.
