PROGRESSIVE LENSES FITTING GUIDE
This is an indispensable guide for all eyecare professionals. A comprehensive reference on the prescribing and correct fitting of progressives. It guides you through each step, from initial patient consultation to delivery of the spectacles.


PRACTICAL REFRACTION
This volume details (in 56 pages) proven techniques of refraction from a practical point of view. It is designed as a chairside tool for the eye care practitioner. A source of reference for your everyday practice!

PRACTICAL LOW VISION
This very practical File covers (in 64 pages) the main notions useful to the eye care practitioner who wants to offer a good quality service to his/her low vision patients. For developing your low vision activity or reinforcing your knowledge!

PROGRESSIVE LENSES
This updated version covers (in 44 pages) all product innovations from the first progressive lens to the more recent designs. You will find valuable details about technical and physiological progressive lens concepts, manufacturing and controlling processes, and a detailed presentation of the designs evolution. For a better understanding of one of the main innovation of the ophthalmic lens industry!

MATERIALS & TREATMENTS
This volume (of 68 pages) aims to present in summary form the essential concepts used in the composition and internal design of lenses. It will take you on a fascinating journey through the very heart of ophthalmic lenses !

COLLECTOR EDITIONS
The "Ophthalmic Optics Files" handbooks were first published in the 80's. This section gathers all the files ever published. Discover them!
 


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.

VARILUX PHYSIO 2.0
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
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.
