Abstract
A soft bifocal contact lens has a carrier lens of soft plastic material shaped and dimensioned to an eye of a user. A central portion of the carrier lens is formed to provide distance-vision correction for the eye of the user. An auxiliary lens smaller than the carrier lens is attached adjacent a lower edge of the carrier lens, and formed to provide near-vision correction for the eye of the user. The auxiliary lens has a contour of a lower edge thereof for contacting a lower eyelid of the user to translate the carrier lens upward when the user moves the eye downward for close vision.
