Varilux Physio®

is designed for

High Resolution Vision

to meet specific physiological

needs

in each area of vision…

Welcome to

High Resolution Vision


Far VisionPhysiology: Coma impacts visual acuityVarilux Physio®: Coma ControlBenefit: enhanced visual sharpness

Intermediate VisionPhysiology: the eye prefers focusing on vertical linesVarilux Physio®: Axis ControlBenefit: enhanced acuity fields

Near VisionPhysiology: the eye explores a big area of the lensVarilux Physio®: Power ControlBenefit: sharpness and extended acuity fields for greater comfort

Wavefront aberration


Coma aberration and PALs

“Coma” aberration is generated by local power variation and exists therefore in all PALs

It gives an asymetric image in the shape of a comet

Impact of Coma’s is particularly important in FAR VISION, as the pupil diameter in Far Vision is bigger

Control of Coma guarantees an optimal visual acuity and better contrast in Far Vision.

The Varilux Physio® exclusivity: controls even higher order

aberrations

Enhanced Vision Sharpness

Coma Control


Physiology: In presence of astigmatism the eye naturally focuses on vertical lines

All PALs generate some astigmatism around the meridian (power variation effect)

The eye accommodation is low

PALs should locate the vertical foci close to the retina

The axis of the residual astigmatism has to be vertical for the Intermediate Vision (+cyl)90°

Varilux Physio® exclusivity: controls astigmatism

and directs the axis vertically

Why ?How the « 5D » influence wavefront aberrations

Wavefront aberrations analyses for different eye-lens system configurations (different positions of the lens on front of the pupil)

The lens positioning in front of the pupil does influence

the value of the aberrations

the location of the areas of clear vision

All distance, intermediate and near zones are impacted

… but the most important impact is in the near zone
