CooperVision® Proclear® multifocal contact lenses have a proven track record of providing outstanding vision, health and comfort. And the Proclear multifocal lens-fitting system offers you more control and flexibility when fitting presbyopic patients. Featuring Balanced Progressive Technology, Proclear multifocal lenses combine spherical and aspheric optics and unique zone sizes to produce a “D” lens for the dominant eye and an “N” lens for the non-dominant eye. These two lens designs work together to maximize binocular visual acuity at all distances—near, intermediate and far.
