Today on World Sight Day WHO joins partners around the world to issue a call to "Make Vision Count". The underlying message is for countries to be aware of the extent of blindness and vision impairment. Around 253 million people live with vision impairment worldwide, of which 36 million are blind. The vast majority live in low-income settings. More than 80% are aged 50 years or above.

Today on World Sight Day WHO joins partners around the world to issue a call to "Make Vision Count". The underlying message is for countries to be aware of the extent of blindness and vision impairment. Around 253 million people live with vision impairment worldwide, of which 36 million are blind. The vast majority live in low-income settings. More than 80% are aged 50 years or above.

Overall, the prevalence of vision impairment has decreased since the early 1990s. The substantial reduction in onchocerciasis and trachoma and the increased availability of eye care services have played an important part in this reduction. Today, uncorrected refractive errors and un-operated cataract are the top two causes of vision impairment. Other contributors to this burden include age-related macular degeneration, glaucoma and diabetic retinopathy.

While there has been some progress, however, it is estimated that the number of people with vision impairment could triple due to population growth and ageing. For example, by 2050 there could be 115 million people who are blind. Yet it is estimated that more than 80% of all visual impairment can be prevented or cured. Measures to do so should focus on increasing access to quality comprehensive eye care services, including at the community level.

"Today's World Sight Day is a reminder that vision is a critical part of how we interact with the world around us, affecting family life, education and employment," notes Dr Etienne Krug, Director of the WHO Department for the Management of Noncommunicable Diseases, Disability, Violence and Injury Prevention. "Protecting vision is an integral part of universal health coverage and is vital for achieving the Sustainable Development Goals."

WHO's work to prevent blindness and vision impairment is guided by the Universal eye health: a global action plan 2014-2019, approved by the World Health Assembly in 2013, with the aim of achieving a measurable reduction of 25% of avoidable visual impairments by 2019. In this regard WHO supports Member States to undertake assessments and develop policies and plans to improve access to comprehensive eye care services.

Tools such as these have been integral to this work: Eye care service assessment tool; Tool for assessment of rehabilitation services and systems; and Tool for the assessment of diabetes and diabetic retinopathy. Other priority areas include the prevention and management of diabetic retinopathy and the building of human resource capacities for eye care.

In addition WHO colleagues and experts from around the world are currently developing a World report on vision, which is expected to be launched towards the end of 2018. The report will provide authoritative evidence on the magnitude of vision loss globally, as well as its prevention, treatment and rehabilitation.
