A contact lens comprising an optical zone and at least one light-blocking ring-shaped zone, wherein the light-blocking ring-shaped zone is disposed around a center point of the contact lens. When certain conditions are met, excessive light can be avoided and sufficient amount of light can be absorbed, which can reduce the photophobia problem, and further eliminate peripheral aberrations, thereby improving the sharpness and sharpness of the image in the field of view. |
