Eye Color Chart: Understanding Eye Colors

Eye colors fascinate and amaze people due to it being a genetic trait that parents can observe in their children as they grow and develop. It is especially exciting for people to imagine what eye color their kids can possibly have. Children’s eyes can be expected to turn out as hazel, green, gray, blue, brown, black and they can even be a combination of different colors.

Generally speaking, children’s eye colors are largely determined by the genetic contribution of each parent. However, the said genetic materials can combine and mix in a variety of unique and exciting ways. The exact eye colors of children can only be truly known and identified once the child is actually born.

 

How Do Eye Colors Develop?

The iris is the colored portion or area of a person’s eyes. This area has certain pigmentation that can determine the color of a person’s eyes. The eye color of human beings usually starts with three (3) particular genes. Out of these three (3) genes, only two (2) have been fully understood. The aforementioned genes are responsible for some of the more commonly observed eye colors such as blue, brown, and green. Colors that are not so common such as hazel, multiple color combinations and gray are still not fully explained or understood by experts at present.

People used to think that the recessive color for the eyes is the color blue while the dominant color would be brown. New evidence suggests, however, that the simple explanation for dominant and recessive colors are not that simple. In addition, the notion that eye color may come from a combination of the parent’s eyes similar to the combination of certain colored paints is not accurate. Each parent can contribute his and her own set of unique chromosomes which means any multiple combinations may be possible. In fact, the eye color of children may be likened or compared to spinning the wheel from the wheel of fortune where a vast amount of color options and blends are available

Recent research is trying to find a way to accurately determine the eye color of individuals using sophisticated DNA analysis. The said research and study claims to be able to predict the eye color of individuals with an accuracy rate of ninety percent (90%). A study as recent as 2010 also claimed that researchers are looking into the possibility of predicting different colors of the eyes through a further DNA analysis that links with the genetics of how eye colors are determined and developed. This research may also prove to be useful in forensics as it can help forensic experts to better come up and identify the facial features of a crime suspect.

Change in Eye Color

Most infants and babies are born with eyes that are colored blue which may eventually turn or transform into the color brown after three (3) years. This is because the development of melanin as a person grows older will also result in the further accumulation of the said pigmentation which in turn leads to the darkening of the color of the eyes.

Children can also have different eye colors from that of their parents. However, parents with brown eyes have a higher possibility or chance of having kids with brown eyes as well. Darker colors usually dominate the lighter ones so it is expected that brown colored eyes can be more dominant than green colored eyes while green colored eyes can be more dominant than blue colored ones. There are also cases where children’s eye colors don’t match for both left and right eyes and this can be caused by certain problems during the infant’s development and other health conditions such as Horner’s syndrome, freckle of the iris or diffuse nevus, and inflammation. The best way to determine if there are any problems or issues with one’s eyes is to have a medical checkup to ensure that nothing serious is actually happening to the eyes.

 

What Causes Changes in the Colors of the Eyes?

The iris, or the part of the eye with pigmentation, has the ability to contract and expand to control and manage the size of the pupils. An individual’s pupils can reduce in size in lighting that is bright and grow larger in low or dim lighting. The pupils can also contract or reduce in size when individuals focus their eyesight on something such as when reading a book or their notes. This movement in the iris or the expansion and contraction of the iris can result in the movement of the pigment inside it as well resulting in changes in the colors of the eye.

Another possible reason for eye color change is the change in emotions for individuals. This is because some emotions or feelings can change or alter the size of the pupil as well. It is normal then for people to sometimes claim that their eye color changes depending on their emotions and their moods.

The colors of the eyes can also age as people grow older. Some examples would include individuals with dark brown eyes may now have hazel colored eyes. It is important to note however that drastic eye changes must immediately be coordinated to the patient’s medical partner for further medical evaluation.
