Clear55A® was designed to provide an optimal balance of handling, comfort and vision. The lens has been enhanced with aberration correcting aspheric optics to optimize the overall visual experience and encompasses a design philosophy that addresses the wearer's handling and comfort needs.
The performance of Clear55A® has been extensively tested through a range of clinical studies including a 120 patient double masked crossover study where it was compared with Acuvue® 2, Biomedics® and Frequency® 55A.
Clear55A®'s visual acuity is optimized over the power range and the incorporation of aberration correcting aspherics provides wearers with maximum contrast sensitivity, particularly in low illumination where it is needed most.
Patients who normally require low amounts of toric correction can benefit from Clear55A® as the aspheric optical design can successfully mask low levels of astigmatism.
Clear55A®'s peripheral and edge design provides a balance between excellent comfort and assured handling. The comfort and handling of Clear55A® was preferred by wearers compared with other leading brands.
Clear55A®'s larger diameter assists in centering the lens on the eye and ensures a wide latitude of fit over a wide range of corneal sizes, providing practitioners with a versatile fitting lens.
