Increased Rise of Childhood Myopia
It is reported that greater than 80% of urban Asian children suffer from some form of nearsightedness (myopia).4
In East and South-East Asia the prevalence of myopia has increased rapidly in the last 50-60 years, particularly in urban areas of Singapore, China, Taiwan, Hong Kong, Japan and Korea. 80-90% of children completing high school are now myopic.5
In a recent study, the mean prevalence of myopia among 7 year old Taiwanese children increased from 5.8% in 1983 to 21% in 2000. At the age of 12 the prevalence of myopia was 36.7% in 1983, it increased to 61% in 2000. For 15 year old it was 64.2% in 1983, increasing to 81% in 2000.6
Isn’t it time Paragon CRT® Contact Lenses become your primary treatment option for childhood myopia? Join an elite group of worldwide eye care practitioners who prescribe Paragon CRT® Contact Lenses as their first and preferred choice to treat childhood myopia.
Myopia is no longer a children’s vision issue, it’s a worldwide health concern. The risk of retinopothy for high myopes increases with age, especially over age 40 as shown in the chart above. If a patient’s myopia is eliminated or reduced before the eye stops progressing (before adulthood), the risk of developing retinopothy is significantly reduced.

For many, the term ‘nearsightedness’ evokes an image of a school-aged child wearing glasses to correct a common condition so they can clearly see a blackboard. But in areas such as East Asia rates of myopia are disturbingly high. Studies in Taiwan have shown that 93% of 18-year-old girls there are myopic.7 In Singapore around 70% of college graduates have the condition8 and in China, a country of well over one billion people, studies have shown rates as high as 78% among 15-year-old children living in urban areas.9 In the US the prevalence has increased markedly in the last 30 years – from 25% in the early 1970s, among those aged 12 to 54 years, to over 40% now.10
Since 2003, Brien Holden Vision Institute with collaborators through the Vision CRC, have been developing methods using an optical device to slow the growth of the myopic eye and reduce the risk of progressing to high levels of myopia. The Institute is now conducting clinical trials on these innovative lenses in China and is headquartered in Sydney, Australia.
As well as the development of technical advances, the Institute has continued to increase access to eye care for people in China. Shanghai BHV-OPTINOVA Vision Research & Training Centre, a joint initiative of Brien Holden Vision Hong Kong Limited and Nova Vision Optical (HK) Limited, conducts research, vision product testing and technical training for eye care practitioners. The Centre is also taking the role of academic and industrial exchanges that radiates international collaborations all around the country.
At the Shanghai International Optic Fair, which took place 18-20, February, 2014, Professor Brien Holden, CEO, Brien Holden Vision Institute, gave a lecture to discuss the prevalence of myopia in Chinese adolescents, as well as the significant role of eye care specialists in eye health.
The Institute’s CEO, Professor Brien Holden said: “What we need are treatments that effectively slow the progress of myopia which will significantly reduce the prevalence of high myopia. A reduction in the rate of myopia of 33 % could produce a 73 % reduction in myopia above 5.00 D.”11
The Institute recently released a report that highlighted the scope of the unprecedented rise in myopia. A Vision for All to See is available on the Institute’s website. Please click here to read more. This website also includes more information about myopia research and development.
Supported By An Unrestricted Educational Grant By Paragon Vision Sciences – MyopiaControl.org
It is our focus to be the world’s leading prescribed product for managing myopia through Orthokeratology with Paragon CRT® Contact Lenses. In order to support industry awareness of myopia management by providing access to hundreds of publications, reviewing the latest methods on how myopia is controlled, and inform of future studies, Paragon Vision Sciences has joined forces with Vision Research Institute (VRI) at Ferris State University through an unrestricted educational grant to create the website, MyopiaControl.org.
There is a long history of research on myopia to uncover the progressive nature of this refractive condition, however, there are many questions that remain unanswered. MyopiaControl.org is the gateway to understanding the severity of the unprecedented rise in myopia, reviewing past and current topic specific literature and keeping up to date with the initiatives in place that aim to control this disease. Paragon Vision Sciences is proud to be associated with the educational value this website offers practitioners around the world.
