Abstract
An intraocular lens, for use within the human eye, contains three concentric regions. An innermost region provides far-field vision. A middle region, surrounding the innermost region, provides near-field vision. An outermost region, surrounding the middle region, provides far-field vision. The intermost region is of a size such that, when the pupil constricts in bright light, the innermost region remains exposed to incoming light, and can thus focus distant images in bright light.
