Visual Perception

Visual perception is the ability to interpret the surrounding environment using light in the visible spectrum reflected by the objects in the environment. This is different from visual acuity, which refers to how clearly a person sees (for example "20/20 vision"). A person can have 20/20 vision and still have problems with visual perceptual processing.

Pronunciation

/ˈvɪʒʊəl pərˈsɛpʃən/

Etymology
