Abstract
Disclosed are lenses and methods for verifying a lens with an induced aperture. The lenses can have a geometry that, among other things, maintains a centered position about a wearer's eye to prevent more than a permissible amount of movement of the lens relative to the eye. Further disclosed is a method for verifying the power profiles used with the lens, and a lens that can have a single power profile for a wide range of presbyopia.
