Abstract
Contact lenses include three or four annular spherical or aspherical optical zones for improved bifocal vision with reduced glare and blurriness in which the boundaries of certain of the distance and near power zones are established in relationship to the user's pupil size at differing illuminations. A device to measure pupil size at varying illuminations to assist in making the improved contact lenses is also disclosed.
