What percentage of the world population is estimated to have low vision?

The estimated percentage of the world population with low vision is approximately 3.5%. This figure highlights the global prevalence of low vision, which is a significant public health concern. Low vision refers to visual impairment that cannot be fully corrected with standard glasses or contact lenses. It can result from various conditions, including cataracts, diabetic retinopathy, and age-related macular degeneration. Understanding this estimate is crucial for developing appropriate resources, services, and policies to support individuals living with visual impairments. Recognizing the extent of low vision in the population underscores the importance of accessibility practices and technologies designed to assist those affected. This knowledge also helps inform healthcare initiatives aimed at prevention and treatment.
