How much alcohol do you consume. Recent research based on more than 12,000 Caucasians showed that people with blue eyes tend to consume more alcohol than individuals with dark eyes. According to the authors, from Atlanta State University (USA), the link is due to the fact that individuals with brown eyes are genetically more sensitive to the effects of alcohol, and for that reason they avoid abusing its consumption.
Are you curious? The level of curiosity of an individual, understanding this as the “desire for knowledge and new experiences”, can be quantified by analyzing the movement of their eyes when contemplating a series of images, as Evan Risko has shown in a study released in the Cognition magazine.
Skin diseases. Based on the color of an individual’s eyes, it is possible to predict which skin diseases they are at risk of suffering from, according to a study released in Nature Genetics . Without going any further, people with brown eyes are less likely to be victims of melanoma, the most dangerous skin cancer. And those with bluish irises are less likely to get vitiligo, a degenerative autoimmune disease that causes a loss of uneven skin pigmentation with the formation of white patches on the face, hands, feet, elbows and knees.
Your personality Individuals with more crypts in the iris – the wavy filaments that radiate from the pupil – tend to be more honest and sensitive, in addition to experiencing more positive emotions. This is the conclusion reached by Mats Larsson, from the University of Orebro (Sweden), after comparing the thickness and density of the iris of half a thousand subjects. Their studies also revealed that concentric folds around the iris are more abundant in impulsive and nervous people. The key to this association between the iris and personality lies in the Pax6 gene , which is involved in the growth of eye tissue, but also in the development of an area of the brain known as the anterior ungulate cortex that regulates mood and where self-control resides.
