We are at GMT+01 summer (Paris / France) Points de Vue - International Review of Ophthalmic Optics cl2 Number 72 - Autumn 2015 Eva Lazuka-Nicoulaud Director of the Publication EDITO DIGITAL VISION Between the time spent drafting an editorial on your tablet, looking at your smartphone, checking traffic on your GPS, then arriving at the office and answering e-mails on your laptop, reading a few e-documents, attending e-conferences via hangouts, always with your eyes riveted to the screen - then returning home and checking the news and social media on your PC or leafing through your e-book, you can spend several hours a day in front of screens of various sizes. These days it’s perfectly common to live in this ultra- connected and multi-screen environment. If we’re to believe the latest research, nearly 61% of Americans spend more than five hours a day in front of a screen*. On average we use four different screens per person, either simultaneously or in succession**. That’s cer- tainly a widespread practice, but it’s poorly suited to how our vision system operates. Human eyes aren’t bio- “These days it’s perfectly logically designed for near vision, which is supposed to be limited to a brief accommodation reflex. Staring common to live in this ultra- wide-eyed into digital devices while maintaining a rigid connected and multi-screen and largely unnatural posture is bound to have physio- logical repercussions. Digital asthenopia affects up environment” to 90% of all users**, and reports of physical pain, ophthalmic disorders and endocrine disruption affecting melatonin or cortisol secretion*** - all potentially the result of overexposure to displays - are multiplying. These findings underscore the paradox between a digital society and physiological reality, and prompt the question: can we live (well) in a connected world? The vision health sector is offering a wide range of solutions for tackling that question: new diagnostic tools, personalized protocols and treatments, advances in ophthalmic optics and lens technology, patient education and awareness, and so on. The new technology itself is making a contribution, thanks to mobile apps, connected devices, big data, professional networks and sites that publish scientific studies and help in education, coordination and collaboration between stakeholders. And since the ophthal- mic optics industry is first and foremost a field of innovation, there is a continuing focus on research and development, both to design innovative devices and to conduct clinical studies that will help us identify risks and outline new preventive or curative strategies. In this 72nd issue of Points de Vue, we try to make sense of these latest trends and developments by once again calling on experts from around the world as well as digital artists, to give us a multi-faceted perspective on digital technology and its implications. Our multi-screen existence is opening up a host of technical, cultural, social and en- tertainment possibilities that are changing the way we view the world and redefining our societies... and their relationship with vision health. It’s our role to anticipate needs and face up to the major challenges posed by the digital world, to live well while being Zen and connected! *2015 report from The Vision Council, USA; see article on page 14 ** 2014 international Ipsos study; see article on page 38 *** Experts’ voice; see article on page 06 Points de Vue - International Review of Ophthalmic Optics www.pointsdevue.com Number 72 - Autumn 2015 3 CONTENT 72 AUTUMN 2015 - BI-ANNUAL - OFFERED © 2015 ESSILOR INTERNATIONAL WWW.POINTSDEVUE.COM 03 EDITORIAL 37 MARKET WATCH 38.

  • Eye Tester's Manual
    EYE TESTER’S MANUAL Before using your vision (eye) tester GnomE read this manual carefully to ensure correct use. 1. GENERAL INSTRUCTIONS The home Eye Tester GnomE (or Tester) is a compact, autonomous optical instrument protected by the patent of Russian Federation No. 2202937. The main function of the Tester is to quickly check the parameters of the vision on your own at home or at working place. The Tester can be used in room conditions: - ambient temperature from +10 C to +35 C; average humidity at ambient temperature +25 C from 30% to 80% Absolute measurement accuracy is 0.25 diopter. Dimensions: 14 mm in diameter and 75 mm long Weight (without a case) up to 20g As the Tester is used in proximity to eyes take care of your movements. The Tester is made from safe materials (glass and metals). Please, avoid strong impacts caused by bumping or dropping the tester. The Tester imitates the operation of different kinds of glasses when eye watches remote objects. MEASURING PARAMETERS OF VISION. Checking near- and farsightedness Sit down and make yourself comfortable, take off your glasses or contact lens and hold that part of the Tester where the objective is with your hand (see photo). Look inside the tester through a lens with a checking eye, and read minimal and maximal digits at the scale. The scale looks like a watch, where 12 o’clock corresponds to zero on the scale and normal vision. There are negative values to the left from zero, and positive numbers to the right on the scale too.

  • LENS EFFICIENCY-A CLINICAL CONCEPT*T the Accommodation
    Br J Ophthalmol: first published as 10.1136/bjo.30.5.291 on 1 May 1946. Downloaded from LENS EFFICIENCY 291 LENS EFFICIENCY-A CLINICAL CONCEPT*t BY JOSEPH I. PASCAL NEW YORK THE fact tllat a lens has a different effectivity depending upon its position before the eye is well known. We say a convex lens gains in effectivity when moved away from the eye and loses in effect- ivity when moved closer to the eye. A concave lens behaves in just the opposite way. There is, however, another feature of changes in lens power which is not dependent upon movement farther from or nearer to the eye. This variable lens effect may be -called its "efficiency," which may be of an ascending order, termed positive efficiency or of a- descending order termed negative efficiency. A similar gradation of efficiency may be postulated with r8ference to the accommodation. It is well known that if a natural emmetrope, an uncorrected hypermetrope and an uncorrected myope each accommodate the same amount, they are not all focused for the same distance. But this is also true, though to a less extent, for the corrected hyperme- copyright. trope and the corrected myope. The prevalent idea that the cor- rected hypermetrope and the corrected myope accommodate 10 D. for one metre, 20 D. for 1/2 mm. and so on is not correct. For example, the natural emmetrope accommodating 3 0 D. is focused for 333 mm. from the eye. But the 2 0 D. corrected hyper- metrope and the 2-0 D. corrected myope when accommodating http://bjo.bmj.com/ 3 0- dioptres are focused for 360 mm.

  • Analysis of Accommodation Capacity in Presbyopic Patients with Low Body Mass Index
    294ARTIGO ORIGINAL Análise da capacidade de acomodação em pacientes présbitas com baixo índice de massa corporal Analysis of accommodation capacity in presbyopic patients with low body mass index Nadyr Antonia Damasceno1, Eduardo de França Damasceno2 RESUMO Objetivo: Correlacionar o índice de massa corporal com condição de baixo peso como possível fator de influência sobre a presbiopia. Métodos: Estudo transversal envolvendo 1030 pacientes com acuidade visual de 20/20 emétropes, com faixa etária entre 36-40 anos, 51-55 anos e 60-65 anos, sendo excluídos pacientes com cover testes positivo, anisometrópicos, com insuficiência de convergência ou alta correlação de convergência / acomodação. Avaliação do índice de massa corpórea de todos os pacientes, como variável pesquisada de presença ou ausência de baixo índice de massa corporal. Resultados: Não houve diferenças estatísticas significativas entre baixo peso e pesos maiores, quando se comparam os dois grupos em relação ao sexo e faixa etária. Houve significância estatística quando se correlacionou indivíduos de baixo peso corporal (IMC < 18,5) e menor expressão de presbiopia em indivíduos com faixa etária entre 51- 55 anos e na faixa etária entre 60-65 anos. Conclusão: Conforme demonstrado pela análise estatística há uma correlação significativa entre baixo peso corporal definido como índice de massa corporal abaixo de 18,5 e menor incidência de presbiopia ou retardo de sua instalação e evolução com a idade. Descritores: Presbiopia; Baixo peso corporal; Índice de massa corporal ABSTRACT Purpuse: To determine the correlation between presbyopia and body mass index. Methods: Cross-sectional study involving 1030 patients with visual acuity of 20/20 emmetropy, aged between 36-40 years, 51-55 years and 60-65 years, excluding patients with positive test cover, anisometropy with convergence insufficiency or high correlation convergence / accommodation.
