Eye Anatomy

---

It is an accepted fact that although the human eye is very small, having a diameter of approximately only 1 inch, this tiny organ provides an extremely significant function – it provides us with sight. Of our 5 senses it is possibly the most used and of course it is one of our primary means to gather important information drawn together from our environment. The study of eye anatomy is thus of extreme importance.

The eye can be compared to the camera. Each of those gathers light, and then by transforming it into a "picture" our brain can then relay it to our mind. Both also must have lenses in order to focus this incoming light.

When the camera receives this incoming light, it makes use of the film in order to create the picture. By studying eye anatomy, we have found that the human eye instead uses a particular deposit of cells, referred to as the retina, in order to produce the image.

The eye socket, called the orbit, is fashioned by the cheekbone below the eye, the forehead above the eye, the temple and finally the side of our nose. To finish the effect, pads of fat then cushion the eye within the eye socket, or orbit.

Looking deeper into human eye anatomy, we find that within the orbit can be found lacrimal glands, which are located beneath the external part of your upper eyelid. These glands produce tears in order to lubricate and humidify your eye.

The tears will of course remove foreign matter from your eye by flushing it away. In the inside corner of your eye is a tiny drain called the nasolacrimal duct that draws those tears away.

Most people already know the function of their eyelids in eye anatomy, namely that they work by protecting your eyes from debris such as dirt and dust, and also protect your eyes from damaging bright light. Blinking, of course, spreads the tears from the lacrimal glands to keep your eyes comfortably moist. Your eyelashes often prevent foreign matter from entering your eyes.

Without going into a complete medical description of the physical properties of eye anatomy, you may do that research yourself, the medical parts to the eye are called the conjunctiva, sclera, cornea, anterior chamber, iris and pupil, anterior chamber angle and the trabecular meshwork, the posterior chamber, lens, vitreous cavity, retina, macula, choroid, optic nerve and finally the extraocular musculature.

People who wish to study eye anatomy are directed to become doctors who will specialize in the science of the eyes, as well as their diseases. Many will also become eye surgeons as they advance through the years of schooling to become an ophthalmologist.
