What are Eyes?
Defintion of an Eye: The eyes are specialized sensory organs that receive the visual images and then send them to the brain.
The eyes are small organs about one inch in size. It is one of the most important of the five sense organs of the body. A pair of healthy eyes gives a clear vision that plays an important role in day-to-day activities of life. Humans have binocular vision i.e. both eyes generate a single combined image. The optical structures create an image sensed by the brain and interpreted with the help of neurons.
Thus the eyes help to see the surroundings. The brain does not have sensory abilities of its own and eyes are required to gather information about the surroundings. If eyes work together correctly, they give depth perception, 3-D vision, and colour vision.

Diagram of Eye
The diagram of eye includes both the external and internal structure of an eye. Externally, the cornea and iris regulate light, while the lens internally focuses it on the retina. Photoreceptor cells in the retina convert light to neural signals. The optic nerve transmits these signals to the brain for visual interpretation. Additional structures like the sclera, vitreous humor, and ciliary muscles contribute to the eye functions. In this article, we will study the external and internal structure of an eye along with its functions in detail.
