在心理学中，视知觉是一种将到达眼睛的可见光信息解释，并利用其来计划或行动的能力。这种知觉的结果也被称为视力、目力或者视觉。视觉中不同的组分被称为视觉系统。

Visual pe****tion is the ability to interpret the surrounding environment by processing information that is contained in visible light. The resulting **** is also known as eyesight, sight, or vision (adjectival form: visual, optical, or ocular). The various physiological components involved in vision are referred to collectively as the visual system, and are the focus of much research in psychology, cognitive science, neuroscience, and molecular biology, collectively referred to as vision science.
