The human eyes are known as the organs that belong to the visual system. Their role is to provide humans with vision and the ability to process and receive the visual detail. They belong to a general group of eyes called the camera-type eyes. Like how the camera lens to focus light to the film, the human eye structure called cornea also focuses light onto the retina, which is a light-sensitive membrane.
All About the Eyes Function
The eyes are composed of many parts and they all work together in order to produce a clear vision. The sclera or the white part of the eye, for instance, functions to protect the eyeball. The black dot at the center of the eye is called the pupil and it works as a hole where the light enters the eye. Other details of the eyes function include the iris, which is the colored part of the eye. This part surrounds the pupil. The purpose of the iris is to control the amount of light that enters the eye by changing the pupil size.
Meanwhile, the cornea or the clear window that you notice at the front of the eye works by covering the pupil and the iris.
For individuals with a normally functioning pair of eyes, a sequence takes place as to how the eye sees. First, a light will reflect off a certain object that the eyes are looking at. Then, the light rays will enter the eye via cornea. The light continues to pass through the aqueous humor or the watery fluid and then it will enter pupil in order to reach the lens. The lends will further change in thickness in order to bend the light. On the light’s way to the retina, it will pass through a clear, thick fluid referred to as the vitreous humor. It will then reach the back portion of the eye and will hit the retina. The retina functions by translating the light into the electrical impulses, carrying it to the brain through the optic nerve.
Finally, the brain will interpret the electrical impulses that we observe.

What are the Common Eye Problems?
Malfunctions or problems in any part of the eyes may cause the common eye problems. These include refractive errors that cause blurry vision, glaucoma or the increased pressure of a fluid in the eye, age-related macular degeneration or the gradual damage of the macula cells, and amblyopia or the lazy eye.
There are also other eye problems, including retinal tear or detachment, diabetic retinopathy, and dry eye syndrome.

Zeaxanthin, Vitamin C, Omega-3 Fatty Acids, Vitamin A, and Vitamin E are also good vitamins for the eyes. Both zeaxanthin and lutein are important because they protect eye tissue, macula, and lens, which prevents glare and clears vision.
