What eye color indicates possible alcohol addiction

British experts note, that the color of the eyes can indicate an increased likelihood of alcohol dependence, as well as a number of other diseases.

The shade of eye color is due to different amounts of melanin, a pigment contained in the iris. A lack of pigment “gives” blue eyes, and an excess leads to brown eyes, the study notes. Green eye color is due to an average level of pigment.

Eye color can indicate various health conditions, including alcoholism. A study conducted by the University of Vermont showed that people with light eyes are 54% more likely to develop alcohol addiction than those with dark eyes.

People with dark eyes, as a rule, are more sensitive to ethanol and experience intoxication more quickly. They have more chances to control their condition in the future.

Eye color can affect not only the tendency to alcoholism. According to a study published in the American Journal of Ophthalmology, people with dark eyes are more likely to develop cataracts, a clouding of the lens that can lead to vision loss.

In addition, brown-eyed and black-eyed people are more prone to vitiligo. This is a dermatological disease, when part of the skin stops producing pigment due to the destruction of melatonin. As a result, part of the tissue loses color, creating a “mottled” or “white spot” effect.

According to the Skin Cancer Foundation, blue-eyed, gray-eyed and green-eyed people are at higher risk of sun damage and cancer skin The fact is that their iris has a lower level of protective melanin.

Also, people with light eyes have a high probability of age-related macular degeneration. Degeneration of the macula is called the deterioration of its cells. This causes a gradual loss of vision.

As researchers note, blue-eyed people have weaker eyes because their cornea is twice as sensitive as brown-eyed people. Therefore, people of the Nordic type are less able to tolerate lenses prone to conjunctivitis.

A sharp change in the color of the eye can be a signal of a serious disease, such as pigmentary glaucoma.

Gray circles on the iris are the so-called senile arc, which occurs due to the deposition of fat around the iris. It can appear due to a high level of cholesterol in the blood or heart disease.
