The Varilux Physio Enhanced polycarbonate lens is even more comfortable to wear than the Physio or the Comfort Lens. It is comparable to the Definity Digital Lens.
In addition, the Physio lens improves contrast sensitivity by helping people in day to day situations as, driving at night, reading the newspaper and experiencing the vivid colors in a bouquet of flowers. Varilux has developed an innovative design and manufacturing process—W.A.V.E. Technology—which literally corrects progressive vision to deliver the sharpest progressive vision.
Sharp vision has two key components: Visual acuity and contrast sensitivity. By dramatically reducing or eliminating higher order aberrations, Varilux Physio delivers an improvement in contrast sensitivity—the ability to see visual details and colors--by up to 30%. Varilux Physio is the only lens proven to increase contrast sensitivity in all fields of vision.
The Varilux Physio is made by Essilor, the world's largest maker of high quality eyeglass lenses
