Visual impairment refers to a condition in which an individual experiences limitations or challenges in their ability to see or interpret visual information. This can include partial or complete loss of vision, as well as varying degrees of impairment in visual acuity, contrast sensitivity, color perception, and depth perception. Visual impairment can be caused by a variety of factors, including eye diseases, injury, genetic disorders, and neurological conditions. Research in the field of visual impairment aims to better understand the underlying causes of vision loss, develop effective interventions and treatments, improve access to support services for individuals with visual impairments, and enhance the quality of life for those affected by visual impairment. This research may involve studying the mechanisms of vision, developing assistive technologies, exploring ways to improve educational and vocational opportunities for individuals with visual impairments, and investigating the impact of visual impairment on social and emotional well-being.
