They say the eyes are the windows to the soul. When you look at someone’s eyes, you could know what they are feeling and thinking. Even though it may seem that your eye color is superficial, it can actually tell you whether you are healthy or not.
The reason behind the statement that eye color can be used to determine how healthy a person is comes from the variety of genes (up to 13 genes) that decide what color they should be. The genes that affect your eye color also affect other parts of your body. One of the genes is NCX-4, which can give you a darker eye color. The same gene has the ability to control many of the body’s proteins and the response of the body when it comes to pain.
Your Eye Color
Your eye color, although it may appear to only have one shade, is actually comprised of three pigments: yellow, blue, and brown. The most common color in the world is brown and the least is green. However, there are other combinations that can result to various colors, including gray, hazel, and amber. Some even have eyes that appear purple and there are also individuals who have eyes with dissimilar colors.
Change in Eye Color
It is not rare for babies to change eye color, since the pigmentation takes place for at least six months. You may notice that your baby’s eyes have a light color and then as he or she grows, the color becomes darker. This is not something to be worried about. However, if an adult sees a change in eye color, this may indicate that there is a problem.
For instance, if one eye suddenly becomes lighter than your other eye, this may mean that there is chronic inflammation in the eye known as iritis. When left untreated, this may result to degenerative eye disorders, including glaucoma and cataracts.
The irises are not the only ones that change color. In some people, the white part of the eye called sclera can turn yellowish. If you notice that this is happening to you, you should immediately seek help from a medical professional as this can be a sign that you have a liver disease. Those who have sclera with a bluish tint may mean that there is inflammation in this part of the eye. Ingesting dangerous metals in high levels can also lead to change in sclera color.
Any change in eye color should be reported as this can mean you are experiencing a medical condition. When detected early, most can still be treated; however, when left without attention, it may lead to a much bigger problem, such as in liver diseases.
