Vision is crucial to human life, influencing development, work, and social participation, yet over 2.2 billion people globally suffer from vision impairment, with at least 1 billion cases being preventable or treatable. This book explores the prevalence, causes, and consequences of visual impairment, focusing on conditions like cataracts, refractive errors, glaucoma, and diabetic retinopathy. It provides a global analysis of vision loss, highlighting disparities across regions such as Asia, Europe, and the Americas, with a special emphasis on India, which bears a significant share of the burden. The text reviews initiatives like WHO's VISION 2020 aimed at eliminating avoidable blindness by improving access to affordable eye care. Additionally, it examines the role of adaptive technologies, such as Braille and screen readers, in enhancing education for visually impaired individuals, advocating for inclusive policies and assistive tools. Drawing on diverse data sources, the book calls for collaborative efforts to ensure equitable eye care and education, promoting a vision of global inclusivity and accessibility.
