2 VISUAL EXCELLENCE IN SIMULTANEOUS VISION UNIQUE C2 OPTICAL DESIGN Stabilized Near and Distance Vision Zones Progressive Intermediate Vision Zone Optimized visual performance at any distance thanks to dedicated stabilized optical zones. Distance Vision Intermediate Vision Near Vision Central Near Vision Controlled Spherical Aberrations Fully controlled integration of higher order spherical aberrations allows to increase visual acuity performance : Reinforced depth of focus in near vision throughout miosis Distance vision is preserved whatever the pupil diameter Stabilized zones Increased depth of focus Wavefront Aberration Optic Profile Controlled Combination of Optical Aberrations Optimized Visual Performance Benefits for your practice Accurate fitting results at first trial No compromise on near and distance vision quality increases patient loyalty Smooth transition from low to high add profile without distance vision change Visual contrast preserved Ease of fit and reduced chair time Benefits for your patients Immediate accomodation at every distance Visual acuity maintained throughout the presbyopic evolution process Visual comfort in all activities Quick and accurate response to patients needs Eye Care I really Thanks the C2 M m o s t o f very pos the lens lenses, r when tra objects.
