Document Summary
The primary function of the eye is to gather light and change it into action potential. Light refers to radiation that occupies a relatively narrow band of the electromagnetic spectrum. Low amplitudes waves are seen as dim colors. High amplitude waves are seen as bright colors. --> colors vary by hue (color), intensity(brightness), and saturation (colorfulness or density) C rnea: the clear layer that covers the front portion of the eye and also contributes to the eye"s ability to focus. light enters the cornea and passes through the pupil. A round muscle that adjusts the size of the pupil; it also gives the eyes their characteristic colour. Clear structure that focuses light onto the back of the eye, The lens can change its shape to ensure that the light entering the eye is refracted to ensure it is focused when it reaches the back of the eye.
