As part of a permanently evolving process at Points de Vue magazine, this first issue for 2013 translates our desire for a change of policy: new director of publication, new format with a bilingual format comprising 2 booklets one after the other, new editorial line.

Points de Vue magazine continues to target all ophthalmic optics professionals and it will continue to be published at the same intervals: Spring and Autumn. We will now address one or two themes per issue, linked to news of our new lens products or to scientific news. The magazine will contain at least three main sections: in-depth articles corresponding to the chosen theme, written by authors known to their peers, “product” articles written by Essilor authors and articles on art and vision. Articles supporting the theme will aim to provide scientific grounding that will inform the reader about the theme’s various different aspects.

In parallel, the www.pointsdevue.com website continues to develop, also with new video-interviews with vision science researchers, introduced periodically and linked to the magazine’s current themes. Every one of the magazine’s issues will now go on line, with the exception of the last one, which will be the paper version only. Complementary articles to the ones published in the magazine will be published on this website, specifically designed for on-screen reading and intended for wider distribution and access. Points de Vue will also now feature on social networks such as Facebook, Twitter and YouTube.

As a follow-up to the ultra-violets theme in the previous issue, we look here at blue light, with its variety of effects on our visual and non-visual systems, as well as at the risks linked to visual health and lighting. Short wavelengths have a lifelong cumulative effect and we thought it would be interesting to place alongside this topic a second theme which is that of senior vision. Indeed, with the lengthening of life expectancy, this debate is raised increasingly frequently at ophthalmology and optometric conferences, whence the importance of addressing here this subject which is very much in the news.

These two themes are prefaced by prestigious authors, Professor Yves Pouliquen on the seniors topic and Doctor Thierry Villette on blue light.

After revealing the secrets of the new generation of Varilux S Series in the previous issue, we now introduce you to the secrets of the personalised version of the Varilux S Series, with 4D technology. You will find details in particular of the physiological basis that has permitted this innovation which deals with aspects of binocular vision, and apply to the binocular calculation of progressive lenses.

On behalf of everyone at Points de Vue, I would like to thank our outgoing Director of Publication Marc Alexandre for his work and commitment to this magazine over the past twenty years, giving it, thanks to its international network of leaders of opinion, an international image and scientific legitimacy in the field of visual health and vision correction. We wish him a long and happy retirement.
