2.2 billion people with vision impairment or blindness in the world

Recently, the first world vision report published on the official website of the World Health Organization said that there are 2.2 billion people with vision impairment or blindness in the world. Aging population, lifestyle changes and inadequate access to eye care are the main factors for the increasing number of people with visual impairment, especially in low-income and middle-income countries. Tandesai, director general of who, said that other factors that cause the most common eye diseases include: myopia - staying indoors for a long time and engaging in a large number of "close work" activities, resulting in more and more people having myopia problems, which can be reduced by increasing outdoor time; diabetic retinopathy - more and more people have diabetes, especially It is type 2 diabetes. If diabetes is not detected and treated, it may affect vision. Almost all diabetic patients will have some form of retinopathy in their life. Through routine eye examination and proper control of diabetes, people's vision can be protected from diabetes. According to tan Desai, eye diseases and vision disorders are very common, but they are often not dealt with. Integrating eye care into the national health plan and basic health care services, ensuring to meet the eye care needs of more people through prevention, early detection, treatment and rehabilitation services, is a good strategy to effectively deal with this problem.
