Varilux S Series

Varilux S Series, breaking the limits

Performances of progressive lenses have improved a lot from the first generations launched more than 50 years ago. Nevertheless, there are still some limitations considered as inherent to the very concept of power variation of the progressive lenses surface.


Varilux S 4D

Seeing with two eyes confers many advantages compared with seeing with one eye: a wider field of view, a better performance in terms of visual detection or discrimination, a better 3D perception and better perception of position of objects in space.

Wavefront is a technology that comes from astronomy and that has been introduced in the ophthalmic field at the end of the last century.

Effect of Chromatic Dispersion of a Lens on Visual Acuity

Materials with a high refractive index have a considerable level of chromatic dispersion which, around the periphery of corrective lenses, may affect the wearer's visual acuity. By measuring visual acuity through prisms of increasing chromatic power we have established the relation between chromatic power and visual acuity. The maximum chromatic dispersion of materials useable in ophthalmic optics can be deduced from these results.

Giving full power to the wearer in lens design

Giving full power to the wearer in lens design

There is no question that digital surfacing is opening new horizons in lens design giving crystal-clear benefits to wearers, the full scope of which is not even imagined yet. For the first time ever, lens designers feel capable of giving full power to the wearer.
