The purpose of the human eye is to capture and process visual information from the surrounding environment. This information is then sent to the brain for interpretation and perception of the world around us.
The human eye focuses on objects by changing the shape of the lens. This process, known as accommodation, is controlled by the ciliary muscles and allows us to see objects at different distances clearly.
The human eye is composed of several parts, including the cornea, iris, pupil, lens, retina, and optic nerve. These structures work together to capture and process visual information.
The retina is a layer of tissue at the back of the eye that contains photoreceptor cells, which are responsible for converting light into electrical signals. These signals are then sent to the brain via the optic nerve, allowing us to see images and colors.
The human eye perceives colors through three types of cone cells in the retina that are sensitive to different wavelengths of light. These cones work together to create the perception of color, and variations in their activity can result in color blindness.
