Introducing Essilor Transitions Lenses

Transitions Lenses go from clear indoors to comfortably dark outdoors. With a remarkably smart technology that enables you to see clearly and more comfortably in virtually and light, Transitions Lenses are convenient to wear right through the day.

People prefer Transitions Lenses

In fact, Transitions lenses work so well, a recent clinical study showed 4 out of 5 clear lens wearers preferred them to their regular lenses. Clinical research conducted by New York University, May 2001 Recent advances in Transitions technology mean Transitions Lenses are the clearest, darkest, fastest and smartest range of lenses ever.

* Clearest

Transitions Lenses are clear indoors. They achieve even greater indoor clarity when combined with crizal antireflective coating.

*Darkest

Transitions are comparable to sunglasses in bright sunlight at 23C and tint mildly in indirect sunlight. In high temperatures, they offer the darkest outdoor performance of all variable tint lenses.

*Fastest

When the light changes, they are the fastest adjusting lenses so you always see
clearly and comfortably.

*Smartest

-Transitions are scratch resistant and block 100% of the sun’s harmful UVA and
UVB rays.
-Transitions Lenses are up to 50% lighter in weight than glass.

-Transition plastic lenses are more impact resistant than glass.

Varilux Physio 360°™ Enhanced high resolution vision

This is the first progressive lens ever to incorporate two innovative technologies. W.A.V.E Technology as used in Laser Surgery and Advanced Astronomy, and double-sided Aberration Control, a calculation software patented by Essilor to optimise visual performance. It is the lens of choice for those who are in search of a high-tech and a precise solution for their visual needs.

It offers unsurpassed sharpness and comfort in any activity.

Features and Benefits

Enhanced high resolution vision

*Applied to both surfaces of the lens, W.A.V.E. Technology - Analysis of the Wavefront - is used to analyse the entire beam of light entering the pupil, not just single rays.

*Higher order aberrations can thus be controlled, to provide higher resolution for patients in all gaze directions.

*Every patient's prescription is uniquely digitally surfaced onto the rear surface of the lens, for the clearest possible, and aberration free vision.

NEAR Vision: Increased comfort

*Power Control: The stable zone is extended in the near vision area, giving wearers comfort and better precision.

*85% of the addition at 12mm.

INTERMEDIATE Vision: 30% wider

*Axis Control: The axis of the residual cylinder in the intermediate area of the lens is controlled, by orienting it vertically.

*The eye has a preference for vertically orientated objects.

*The result is a 30% wider intermediate zone.

FAR Vision: unsurpassed sharpness & increased contrast sensitivity

*Coma Control: Coma – a higher order aberration affecting the quality of vision - is for the first time, controlled in a progressive lens.

*Distance vision is sharper.

*Contrast sensitivity is improved.

*Night driving becomes safer.

Multidesign by addition and Rx

*The visual requirements of both myopes and hyperopes are satisfied.

*Progressive meridian varies with addition allowing for reading distance and associated wearers' convergence.

Technical Features

Originating from physiological research, Varilux Physio and Varilux Physio 360° delivers high resolution vision through two ground breaking innovations.

1. Essilor Advanced Digital Surfacing

A process innovation for calculating and manufacturing the lens front and back surfaces. This provides enhanced high resolution vision through double-sided aberration control (matching design and prescription). First Innovative Approach

Wavefront Management System

Varilux Physio 360°

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.

Second Innovative Approcah

Essilor Advanced Digital Surfacing

As both lens surfaces affect the quality of the wavefront, in order to maintain the optimal performance delivered by the lens, a revolutionary calculation and manufacturing process has been created.

Double-Sided Aberration Control

An innovative calculation software patented by Essilor is used to match the front and back surfaces of the lens taking into account all of the combinations of SPH, CYL, Axis and addition for all the directions of gaze.

An advanced digital surfacing process is used to produce the front surface of the lens.
This process is also used to manufacture the back surface of the lens in order to optimise visual performance whenever the prescription demands it. This ensures that the visual acuity will be maintained whatever the prescription is.

CRYSTAL CLEAR LENSES
WITH SUPERIOR SCRATCH RESISTANCE

Total UV Protection

Nikon's Ultra High Index 1.67 material comes with built-in 100% UV protection. As the UV treatment is inserted in the monomer, your customers are assured of 100% UV protection without the risk of peeling or a yellowish tint. They will also benefit from long-lasting protection that's invisible to the eye.
