摘要:
Translating, multifocal contact lens pairs with optical power zones which are dissimilar between the first and second lenses of the pair are utilized for correcting presbyopia in the wearer. Each lens may differ in segment height, power, asphericity, shape, orientation and/or inset of the optical power subzones thereby providing clear and comfortable vision at far, intermediate and near distances.
