Rear Surface Varifocal Lenses
Why Are Some Varifocals Better Than Others?
Fortunately, the individualised approach to Rear Surface Free-Form Lens Manufacturing ensures that every wearer enjoys the clearest distance, intermediate, and near viewing zones, eliminating the happy medium approach of traditional progressive/varifocal lens manufacturing, regardless of prescription or frame selection. Free-Form optimised prescriptions will ensure the widest fields of vision in comparison to traditional progressive/varifocal lens manufacturing. As much as 50% larger viewing zones will be achieved with a Rear Surface progressive.
DuraVision® Platinum
The ZEISS Premium Coating.
The demands of everyday life call for hard, dirt-resistant lenses that are easy to clean. This is precisely why hard, anti-reflective lens coatings exist – but it needs to be said that the quality of these coatings can vary greatly.
What makes ZEISS lenses with DuraVision® Platinum AR coating different? These hard and light lenses are very robust, dirt-resistant and easy to clean while offering first-rate, anti-reflective properties. An integrated system of coating densely layers packed, using ion-assisted deposition, results in a lens surface that is three times harder than the previous generation of hard, anti-reflective (AR) coated plastic ZEISS lenses and 35% harder than AR coated mineral (glass) ZEISS lenses. ZEISS lenses with DuraVision® Platinum AR coating also have a more cosmetically pleasing, blue residual reflex colour, that produces over 20% less luminous reflectance than conventional green AR coated ZEISS lenses. “Read More Here“
