Vision, the most dominant of our senses, plays a critical role in every facet and stage of our lives. We take vision for granted, but without vision, we struggle to learn, to walk, to read, to participate in school and to work. Vision impairment occurs when an eye condition affects the visual system and its vision functions. Everyone, if they live ...
Globally, the leading causes of vision impairment and blindness are: 1. refractive errors 2. cataract 3. diabetic retinopathy 4. glaucoma 5. age-related macular degeneration. There is substantial variation in the causes of vision impairment between and within countries according to the availability of eye care services, their affordability, and the...
Globally, at least 2.2 billion people have a near or distance vision impairment. In at least 1 billion – or almost half – of these cases, vision impairment could have been prevented or has yet to be addressed.

School-age children with vision impairment can also experience lower levels of educational achievement. Vision impairment severely impacts quality of life among adult populations. Adults with vision impairment can experience lower rates of employment and higher rates of depression and anxiety. In the case of olde...
Economic impact
Vision impairment poses an enormous global financial burden with an estimate annual global productivity loss of about US$ 411 billion purchasing power parity (3). This figure far outweighs the estimated cost gap of addressing the unmet need of vision impairment (estimated at about US$ 25 billion).
There are effective interventions covering promotion, prevention, treatment and rehabilitation which address the needs associated with eye conditions and vision impairment. While many vision loss cases can be prevented (such as those due to infections, trauma, unsafe traditional medicines, perinatal diseases, nutrition-related diseases, unsafe use ...
WHO’s work is guided by the recommendations of the WHO World report on vision (2019) and the resolution on "integrated, people-centred eye care, including preventable blindness and vision impairment" adopted at the Seventy-third World Health Assembly in 2020. The key proposal is to make integrated people-centred eye care (IPEC) the care model of ch...
With 8 million blind people and 62 million visually impaired, India shares almost a quarter of the entire global burden of blindness and vision impairment. Blindness reduces productivity, quality of life and increases the risk of death.
There are an estimated 4.95 million people blind (0.36% of the total population), 35 million people visually impaired (2.55%), and 0.24 million blind children in India.
The National Blindness and Visual Impairment Survey 2015-2019 was conducted in order to provide evidence about the present status of blindness and visual impairment in India. The survey was planned by the Ministry of Health and Family Welfare, Government of India.
Globally, 1.1 billion people were living with vision loss in 2020. - 43 million people are blind (crude prevalence 0.5%) - 295 million people have moderate to severe visual impairment (crude prevalence 3.7%) - 258 million people have mild visual impairment (crude prevalence 3.3%)
