Be philosophical or not, there is hardly a soul on this earth that’s not fascinated by the wonders of science. Now, it’s true to each of their own that is, some prefer the majesty of pure mathematics, while others prefer more practical studies like applied physics. However, if one were to search for common ground in this torrent of scientific curiosity, the crown would surely go to the study of human anatomy.
Prepared under the supervision and edited by a top Kuwait LASIK center, this article is intended to satisfy a particular scientific fascination i.e., the human eye. Although structurally complex and rich in its anatomy, the human eye is without a doubt one of the simplest organs to understand. So, strap on because this short and simple read will detail all; the basic structure, functioning, and conditions of the human eye.
It is somewhat common knowledge that the eye functions like modern-day cameras; in fact, the first cameras (pinhole cameras) were based on the eye. However, to be able to understand the mechanism of the eye, it is important to first understand the function of its several components.

The Anterior Organelles
Table of Contents
|Cornea||The outermost visible and protective layer of the eye. Assists with light focus.|
|Aqueous Humor||A transparent water-like fluid that gives the eye its structure. Also forms tears.|
|Iris||A thin muscular structure that regulates the amount of light entering the lens.|
|Lens||Functions like regular lenses. Focus light on the retina|
|Suspensory Ligaments||Controls the focal point of the lens.|
The Posterior Organelles
|Sclera||The outermost protective layer of the eye. Different from the cornea.|
|Vitreous Humor||A dense fluid that provides structural support and helps focus the light.|
|Retina||The innermost and image-sensing layer.|
|Optic Disc||A dip in the retina where there are no light-sensing cells. Essentially a blind spot.|
|Optic Nerves||Attached to the retina through the optic nerve. Serve to relay to the brain visual information.|
Principle of Light Detection
According to the physicians at the top Kuwait LASIK center, the principle of light detection for the human eye is quite similar to that of modern-day cameras.
- Light is converged onto the lens by the cornea.
- The iris controls the intensity of light going to the lens.
- The lens changes shape to better focus the light onto the retina.
- The retina relays visual information to the brain through the optic nerves.
Structural Abnormalities: Causes, Consequences & Cures
Like most human organs, the eyes are also prone to abnormalities. The most common of these abnormalities (short-sightedness, far-sightedness, and astigmatism) are collectively termed blurry vision disorders. All these conditions are caused by structural abnormalities in the eye that cause the image not to focus on the retina. Fortunately, all of these conditions are effectively cured through laser eye surgery. Performed by the well-renowned Kuwait LASIK center, laser-assisted in situ keratomileusis (or LASIK) is the most commonly performed laser eye procedure.
The human eye is truly marvelous; however, due care is required for it to be able to perform its function. And everyone will agree that the eye’s function is one of utmost importance. Furthermore, be careful not to make any rash decisions, like getting an eye procedure, before properly consulting a professional and reliable physician. Other than that, due care must be taken with contact lens applications – as they can often scratch the corneas, as well as cause severe dryness.
