Our eye colors and their possible variations can be fundamental in identifying possible illnesses and or health problems at an early stage.
Eye color does more than simply give shine, beauty, and distinction to your life. They also reflect many things about you.
It is very typical to see that eye tonality is passed down from one family member to others. However, you will not always see two people with the exact same tone, even if they are twins.
This is because of all the genetic factors that come into play. Whether they be brown, hazel, green, blue, gray, or some combination or variation of those colors, your eyes will say more than what your lips reveal.
The expression alone that “the eyes are the windows to the soul” defines what a simple look can do. Your eye color could dictate your risk of certain illnesses and could even predict how your body processes alcohol.
I bet you weren’t expecting that, were you? Well, there’s no need to be worried; here, we will share with you some of the secrets that your eye color says about you and your health.
1. People with dark eyes are more likely to have cataracts
This is a blurring of vision very common nowadays that we associate with aging. A cataract is like a cloud or fog that appears over the pupil. People with a dark eye color run a higher risk of suffering from them.
This was proven through a study published in the American Journal of Ophthalmology. The research showed that people with dark eyes had a risk 1.8 to 2.8 times greater of contracting cataracts at some point in their lives.
Nevertheless, this can be prevented. The most important thing is to shield your eyes from ultraviolet rays. However, as getting some sun is also vital to your health, we recommend that you:
- Go out in the sun when it is near its lowest point. Avoid exposure between noon and 3:00 in the afternoon.
- Use good-quality sunglasses. In addition to being a fashion accessory that we all enjoy and use to create our look, the keep the sun’s rays from hitting your eyes.
- You should keep in mind that not all of them really work, and it’s better to choose those made by a good brand. They will be more expensive, but they will also last longer and will protect you.
- Economical sunglasses only serve as a fashion article, while they allow up to 90 percent of solar radiation pass through. Meanwhile, good-quality sunglasses can block up to 90 percent of solar radiation.
2. Vitiligo is less common among people with blue eyes
Vitiligo is a disease of an autoimmune nature that causes loss of skin color in blotches. Some studies have found that it is less frequent in people with blue eyes.
This finding was obtained after studying 3,000 patients with vitiligo. Everyone involved in the study was Caucasian. Twenty-seven percent had blue eyes, 30 percent had green or hazel eyes, and 43 percent had brown eyes.
3. Melanoma is more common in people with blue eyes
Although genetically, melanoma and vitiligo seem to be opposites, that which functions as protection from vitiligo also increases the risk of melanoma.
One theory of why this occurs is that vitiligo is an autoimmune disease. This means that our immune response attacks by a natural error of our own bodies.
The excess of activity of that response could be what makes people with brown eyes more susceptible to vitiligo and, at the same time, what combats melanoma.
The exact relationship is unknown, but some scientists concur that there are three factors that are related
- The genes that protect against vitiligo
- The genes that protect against melanoma
- The genes that determine the quantity and type of skin and eye color.
4. People with dark-colored eyes can be more influenced by alcohol
Think twice next time about whether you will accept that glass. If your eyes are black or brown, it is possible that you have less tolerance for an alcoholic beverage than your friends with blue or green eyes.
This was published in the U.S. scientific magazine Personality and Individual Differences.
Researchers found a greater consumption of alcohol in women with light-colored eyes.
Their hypothesis is that people with dark-colored eyes can be more sensitive to alcohol and other drugs in general, which ultimately makes them drink less.
5. A change in eye color could be a sign that something bad is going on
Have you noticed reddening in the white part of your eyes? It is very likely that you have undiagnosed allergies.
If they become yellow, you might be dealing with a liver problem. If only one of your eyes has changed color, it could be a sign of hereditary disease, such as neurofibromatosis.
Needless to say, if you so much as see a small change in the color of your eyes, you should go to an ophthalmologist.
They are doctors specialized this area of your body, and will tell you if they need to refer you to another specialist, in the case that the change in eye color could be the symptom of another problem.
What is your eye color? Now you will be able to know a little more about yourself and your health based on this factor.
Take the necessary measures to maintain the health of this important organ.
