OPTICAL CORRECTION

UNIFOCAL

The new Unifocal lens with multi-plan atorique and aspherical surfaces. The AO S-Lite lens give's you an high-tech aspherical design. The atorique design has the same effect on astigmatique lenses as aspherical lens for spherical lens.

In this way optimisation for each meridian occur. The atorique surface is made at rear surface of the lens.

AO s-lite avantages:

• Big field of vision and better compensation of aberrations of torique surfaces.
• Extra thin lenses, thank for the flat curves, thin central thickness (1 mm.) and high-index (1.6,1.66,1.74).
• Very good optical performance and scratch resistant, with the X-Five lt coating.
