Retinal Focus Design
Transmitted light will be continuously adjusted during its use to ensure an optimal degree of accommodation over the entire lens surface. This improves image formation on the retina. Making a flatter base curve results in thinning and weight saving advantages. The distinct field of vision has been extended by optimising astigmatism correction.
Optimal Atoric Design
A design with highly effective aberration control compensates for aberration by ray tracing against full astigmatism (extending to the periphery of the lens). The result is an optimal atoric surface and a broadened field of vision.
