A contact lens for monthly replacement with 55% water content, aspheric front surface optimised regarding power, equilibrated back surface design and integrated UV protection
Concept and design
With the new “aberration control system” it is possible to improve vision quality when compared with conventional contact lenses. The difference is in the design of the front surface. Over the complete gradient of the aspheric front surface curvature the lens is optimised as to strength and the thickness adjusted to flexibility at the corresponding correction. The goal is not only to correct low order aberrations, i.e., spheric visual defects, as well as astigmatism but also to go a step further – the reduction of the “spheric aberration”.
