Toric Contact Lens Our PC-58 Toric Contact Lenses for astigmatism were introduced after countless hours of research and development. The lenses are incorporated with our unique double slab-off prism ballast design, which helps to reposition the lens correctly on the eye after each blink so that the lens fits, feels, and focuses just right, every time. Like our Aspheric lenses, the lenses contain MPC, a hydrophilic biomimetic material that occurs naturally in human eyes. MPC creates a cushion of hydration against the surface of the eyes to keep the lenses hydrated while preventing protein and lipids buildup for long-lasting hydration and all-day comfort. MPC is integrated right into the lens, so it won't wear off or dissipate like a coating. All of our lenses come with built-in Class II UV blockers to protect the eyes from an average of 97% of UVB and 87% of UVA radiation We are happy to organize our Contact Lens Samples to your doorsteps for evaluation.
