What determines your Eye Color?
One characteristic that makes your eyes unique and attractive is Eye Color. Color is a trait that fascinates people, and can define your appearance.
From new parents waiting to see if their baby’s blue eyes stay blue to men and women who try to change their Color with Contact Lenses, most people are captivated by the Eye's Color.
Color is found in the part of the eye called the iris.

What determines your Color?
The genetics of color inheritance is actually more complicated than the simple explanation that brown is due to a dominant gene and blue or green colors are due to recessive genes.
Color inheritance is due to many genetic factors. Research by geneticist Rick Sturm of the University of Queensland has shown that the OCA2 gene controls the amount of melanin pigment produced and accounts for 74% of the total variation in people’s Eye Color. According to Sturm’s research, the OCA2 gene itself is influenced by other genetic components.
Color not only plays a major role in your appearance, but in your body language as well by communicating important nonverbal messages in everyday life. As a matter of fact, the study of Eye Color genetics has been pursued in many diverse fields.
For example, law enforcement in the Netherlands may benefit from DNA analysis that predicts an Eyes Color to help identify criminals. Researchers in Rotterdam have identified three new genes to contribute to a person’s Color.
This research was the first to use the full range of colors, from lightest blue to darkest brown. Because of this, this DNA analysis can predict Color in a more detailed way.
The field of behavioral psychology has been influenced by the study of Eye Color genetics. Although research of an Eyes Color as an indicator of genetic predisposition toward certain behaviors has yielded mixed results, a link has been found when color is caused by a cell defect.
Perhaps the cell defect which causes Color, rather than the Eye Color itself, may serve as a crude indicator of behavior.
In a nutshell, predicting your baby’s Eye Color may not be as easy as once believed because Eye Color genetics is more complex than the belief that the brown gene is dominant and the blue gene is recessive.
Changing color has been popular since the late 1980s when opaque color Contact Lenses were first introduced. It has been used in the entertainment industry extensively to cause a myriad of special eye effects.
For example, Contact Lenses have been used to make eyes appear demonic in horror films or even to make the pupils appear dilated in order to simulate a person’s appearance under the influence of an illicit drug like cocaine.
Who can forget the Incredible Hulk eyes as he transformed from Dr. David Banner’s brown eyes into the green monster’s green eyes?
Colored, or as they are sometimes called, Cosmetic Contact Lenses have been used outside Hollywood and for more than just theatrical purposes.
People of all ages, gender and race have used these Contact Lenses to enhance or change the Color of their eyes.

Cosmetic Contact Lenses can play a significant role in helping the cosmesis of patients who have experienced damage or disfigurement of one or both eyes as a result of medical conditions or
The photo on the right shows the effect of a traumatic cataract on this boy.
Cosmetic Contact Lenses can create a brown iris with a black pupil if for any reason the cataract is not operable. See the case above where the man on the left has a small, rotting eye (referred to as a phthisical eye) due to trauma. Similar cosmetic Contact Lenses may help this man.
The wide array of Eye Colors possible for the human eye can sometimes make it challenging to get a perfect match in color between the eyes.

If you desire to change or enhance your color, make sure to consult your eye doctor for a proper fitting of Contact Lenses. Cosmetic Contact Lenses are a medical device like any other type of Contact Lenses. Purchasing these lenses from a beauty supply store without the care of an eye care provider can pose a health risk to your sight.
