New data on the global economic impact and burden of preventable blindness

28 October 2014

To highlight the critical need for access to eye care and regular eye examinations, Novartis and its eye care division, Alcon, introduced new data on World Sight Day that highlights the economic impact and burden that blindness and vision impairment can have on societies and individuals across the globe.

World Sight Day, held on October 9th, is a global initiative to help raise awareness and address the problem of preventable blindness and vision impairment worldwide.

Conducted by Novartis, The European Forum Against Blindness (EFAB) and Deloitte Access Economics, The Cost and Burden of Eye Diseases and Preventable Blindness study quantified the economic impact of vision loss by analyzing the top four eye diseases responsible for vision loss: glaucoma, diabetic retinopathy, cataracts, and wet age-related macular degeneration (AMD), which, in the EU alone, affects one in 10 people.

The study also analyzed the cost-effectiveness of interventions to prevent them. A total of 14 countries were included in the study: Australia, Argentina, Denmark, France, Germany, Ireland, Italy, Mexico, Poland, Slovak Republic, Spain, Sweden, Switzerland and the UK.

The analysis found that within the 14 countries studied, more than 350,000 healthy life years are lost due to cataracts, glaucoma, AMD and diabetic retinopathy, equalling more than 123 million workdays lost per year. In addition, the annual economic costs due to preventable vision impairment and blindness totalled more than €20 billion EUR.

Vision impairment and blindness can be avoided

The analysis found that access to eye care, and early diagnosis and treatment for these eye conditions can have an enormous impact on reducing the disease burden and offset a significant amount of economic cost to society. For instance, screening for diabetic retinopathy, cataracts and AMD alone can offset economic costs by more than €6 billion EUR each year.

Investing in cost-effective interventions has a big impact on reducing the disease burden. Globally, more than 285 million people live with vision impairment and blindness[1]. But, more than 90% of vision problems can be prevented, treated or cured, provided patients have access to treatment[1].

Taking care of your eyes at every age

A person's eye health is constantly changing as they age, with new needs and challenges at different times in life. Eyes at age three are much different from eyes at age 30 or 60. The eyes are also a good indicator of overall health. A range of illness can be detected through an eye examination, including diabetes, high blood pressure, heart disease, and even rare hereditary diseases.[2]

This year on World Sight Day, Alcon is helping people around the world learn about their eye health at every age by providing in-depth, downloadable digital materials intended to help encourage conversations about how to properly maintain eye health and visual function. These materials cover eye diseases and conditions starting at birth to age 60 and older. To learn more about the eyes at every age and the various eye conditions that can affect them, visit
