Visual performance research focuses on understanding and optimizing the abilities of the visual system, including visual acuity, contrast sensitivity, color vision, and depth perception. Researchers in this area may study how factors such as lighting, screen resolution, and viewing distance affect visual performance, as well as developing technologies and interventions to enhance visual performance in various settings such as sports, driving, and reading. The ultimate goal of visual performance research is to improve visual function and quality of life for individuals with visual impairments or those seeking to optimize their visual abilities.
