These lenses are anti-reflective, anti-scratch and have UV protection. In addition they have an anti-electromagnetic radiation surface coating. This invisible barrier filters out 100% electromagnetic radiation waves and does not produce static electricity. This in turn offers even more protection for the eyes.
Progressive lenses digital state of the art technological improvements have created a smooth and consistent transition between differing lens strengths within the lens itself. Also known as “multifocal” or “varifocal” lenses, they offer all of the improvements of the old out moded bi- or trifocal lenses such as a 20% wider scope of view that is undistorted, a unique visual correction design in these lenses is created on the back of the lenses rather than on the front. This allows elimination of the 'key hole effect' common to standard progressive lenses. Digital lenses are surfaced on both sides and often called free-form because the lens is customized to the patient's prescription in a very precise manner.
Perfect for the person who spends a lot of time outside. By blocking horizontal light waves, polarized lenses reduce bright reflection, road glare and increase clarity in bright environments such as driving facing a sunrise or sunset.
