"In addition to requiring good visual clarity, most sports require athletes to possess superior visual performance skills to scan and interpret visual information at differing contrast levels, use visual information at varying depths, switch between stimuli that are at near and far distances, identify stimuli in their peripheral vision, memorize and recognize patterns of movement, execute proper eye–hand and eye–foot coordination, and respond quickly while also being able to execute response inhibition" (Schmidt et al., 2015).

Visual performance is the speed and accuracy of visual processing. One metric for characterizing visual performance is the Relative Visual Performance (RVP) model, described in the following paper: Article Relative visual performance. A basis for application
please read the RVP-Models of M.Rea. It can help you something. RVP means that relative visual performance. Or read the standard AS-NZS 1680.2.5-1997. Regards, Vinh
