It maintains the shape of eye and provide attachment to the extrinsic muscle of eye. It keeps our eyes moist and clear and provides lubrication by secreting mucus and tears. Hover the diagram to zoom.

The optic nerve then transmits these signals to the visual cortex the part of the brain. The layers of the tear film keep the front of the eye lubricated. The eye has several major components.

Of light entering the eye. It is located in the center of the retina. It controls light levels inside the eye similar to the aperture on a camera.

The cornea bends light focusing it on the retina. The macula is the small sensitive area of the retina that gives central vision. These three layers together are called the tear film.

The retina acts like an electronic image sensor of a digital camera converting optical images into electronic signals. The mucous layer is made by the conjunctiva. It refracts light to focus on retina.

It lines the sclera and is made up of stratified squamous epithelium. The surface of the eye and the inner surface of the eyelids are covered with a clear membrane called the conjunctiva. It functions as a window and allows light to enter your eye.

Light then passes through the moisture-containing aqueous humor and reaches the central opening called the pupil which with the help. The lens sits directly behind the pupil. The conjunctiva also covers the interior of your eyelids.

Eyebrows eyelashes and eyelids also contribute to this effort. It is a white visible portion. These glands are located on the outer corner of each eye.

Working of the Human Eye. The cornea is a transparent dome-shaped tissue that forms the front part of your eye. A clear dome over the iris.

Tears lubricate the eye and are made up of three layers. The lens retina and optic nerve are several important parts of your eye that allow you to transform light and electrical signals into images. Pads of fat and the surrounding bones of the skull protect them.

Eye Diagram Handout Author. The lens is a clear part of the eye behind the iris that helps to focus light or an image on the retina. This makes up your vision.

It also begins the process of focusing light rays that allow you to see words and images clearly. When we look at an object the light falling on it is reflected towards our eyes and it enters the eye through the transparent layer of cornea which helps in focusing the light. Read an article about how vision works.

Eyeballs - Eye is a small ball that sits in a little hollow area called the eye socket in the skull. The cornea pupil lens iris retina and sclera. The iris is the coloured part of the eye which surrounds the pupil.

Your eye is a slightly asymmetrical globe about an inch in diameter. A human eye is roughly 23 cm in diameter and is almost a spherical ball filled with some fluid. As tears flush out potentially dangerous irritants it becomes easier to focus properly.

The cornea makes up the front-center part of the eyes outer wall. The eyes sit in cone-shaped cavities in the skull called sockets which are surrounded by 6 motion-regulating muscles and multiple layers of fatty tissue that help to protect the eye and give it flexibility. These work together to capture an image.

The optic nerve carries signals of light dark and colors to a part of the brain called the visual cortex which assembles the signals into images and produces vision. The conjunctiva is the membrane covering the sclera white portion of your eye. Click the parts of the eye to see a description for each.

The pupil is not an actual structure but the circular opening in the middle of the iris. The pupil appears as the dark central part of the eye. It is a thin transparent front part of sclera.
