ABSTRACT:
An annular mask contact lens designed to operate with the normal functioning of the human pupil. An annular mask forms a small pinhole-like aperture on the contact lens enabling continual focus correction. The outer diameter of the annular mask allows the wearer to transmit more light energy through the pupil as brightness levels decrease. The contact lens may be structured with two separate and distinct optical corrections, both at the small aperture region and in the region beyond the annular mask. Functional imaging is thus achieved for both bright and dim lighting, and over a wide range of viewing distances. Cosmetic and peripheral vision enhancement is also provided by the contact lens constructed according to the invention.
