A single vision lens geometry designed to combine optical performance, thinness and aesthetics.
With an aspheric design on both the front and back surfaces, Zephir optimizes the lens shape to better correct peripheral aberrations and reduce thickness. This architecture produces a thinner lens than a conventional single vision lens, for a comparable prescription and fitting conditions.
Benefits
- Better thickness control: The double asphericity optimizes the lens curves and limits thickness, for more discreet and attractive eyewear.
- Optimized visual quality: The design of both surfaces helps to better control aberrations and improve vision quality, especially in the periphery.
- Greater wearing comfort: A thinner lens can also be lighter, which improves the wearer's everyday comfort.
Target wearers
Zephir is particularly suited to:
- wearers looking for thinner, more attractive lenses;
- prescriptions where lens thickness is a major concern;
- thin, lightweight or large frames;
- demanding customers who want a high-value single vision solution.
