Technical Features
Originating from physiological research, Varilux Physio delivers high resolution vision through a ground breaking innovation - Wavefront Management System. This is a design innovation that adapts the wavefront analysis used in laser surgery and advanced astronomy to detect and eliminate higher order aberrations inherent in progressive lenses.
Wavefront Management System
A revolutionary way to achieve high resolution vision Through the concept we consider the way light travels and how the entire wave front of the beam of light passing through the pupil contributes to the clarity of vision. All varifocal lenses, by nature of their design (power variation), deform the LIGHT WAVES as they pass through the lens. This leads to aberrations and acuity loss. Managing the quality of the WAVEFRONT is therefore crucial for clarity of vision. It requires both:
- To analyse the whole beam of light passing through the pupil whatever the direction of gaze.
- To minimise aberrations of the wavefront.
Thanks to the Wavefront Management System, for the first time ever in the spectacle lens field, the calculation of each point of the progressive surface is achieved by taking into account the whole beam of light passing through the pupil rather than a single ray.
Distance Vision
The Wavefront Management System allows us to control the wavefront passing through the pupil in order to reduce higher order aberrations. For the first time the Coma has been reduced, thereby providing unsurpassed sharpness.
Intermediate Vision
The Wavefront Management System allows us to keep the axis of unwanted residual astigmatism vertical in order to match the eye preference. Focusing is made easier and the area of clear vision is thereby increased by up to 30% compared to the latest varifocals.
In Near Vision
The control of the wavefront has allowed us to extend vertically the zone of stabilised near power. The eye can explore a larger area of the near zones without postural adjustments.
