Effective interventions exist for the promotion

Effective interventions exist for the promotion, prevention, treatment and rehabilitation of eye disease and low vision, some of which are among the most cost-effective and easily implemented public health interventions. Trends in the prevalence of blindness and near and far low vision: analysis for the Global Burden of Disease Study. Visual rehabilitation is very effective in improving the functioning of people with irreversible visual impairment, which can be caused by eye conditions such as diabetic retinopathy, glaucoma, the effects of trauma, and age-related macular degeneration. As in adults, uncorrected refractive abnormalities are the leading cause of low vision in children in all countries. In older adults, low vision can contribute to social isolation, difficulty walking, increased risk of falls and bone fractures, and increased risk of early hospitalization in a nursing home. For example, the rate of low vision due to cataracts is higher in low- and middle-income countries than in high-income countries. Causes of blindness and low vision in 2020 and trends over 30 years: an estimate of the prevalence of avoidable blindness due to VISION 2020: The Right to See. Young children with severe and early visual impairments can fall behind in motor, language, emotional, social, and cognitive development, which can have lifelong consequences. There are also treatments for many eye problems that do not usually cause visual impairment, such as dry eyes, conjunctivitis and blepharitis, but cause discomfort and pain. Adults with visual impairments often have lower rates of employment and productivity, and are more likely to suffer from depression and anxiety.
