    摘要： A contact lens has an optical zone with a distance vision zone and a near vision zone. The distance vision zone also has a first area that is sufficient to overlay a substantial portion of a pupil of a user and is disposed in a first position within the optical zone so that the user's pupil is substantially subtended by the distance vision zone when the user is gazing at a substantially horizontal point. The near vision zone is substantially concentric with the rotational axis and extends radially outward from the distance vision zone. The near vision zone has a second radius of curvature that provides near vision correction and has a second area that is sufficient to overlay a substantial portion of the pupil of a user. The near vision zone is disposed in a second position within the optical zone so that the user's pupil is substantially subtended by the near vision zone when the user is gazing at a near vision point below the substantially horizontal point. A ridge zone enables engagement with a lower eyelid of a user so as to provide vertical translation support, and a transition zone provides a smooth transition from the ridge zone to the optical zone.

    摘要： Visual aids and associated methods for improving the eye sight of low vision patients are provided. Generally, the devices of the present disclosure address the needs of age-related macular degeneration (AMD) and other low vision patients by providing a magnified retinal image while keeping a large visual field of view. Further, the devices of the present disclosure allow direction of the magnified retinal image away from damaged portions of the retina and towards healthy, or at least healthier, portions of the retina. The devices of the present disclosure are also configured for implantation within the eye using minimally invasive surgical procedures. Methods of utilizing the devices of the present disclosure, including surgical procedures, are also provided.
