Researchers found a rare case in the eye of the famous Italian painter Leonardo da Vinci, the reason for the ingenious accuracy of his paintings.
According to a study published Thursday in the Journal of Gamma for Ophthalmology, the legendary artist, who was famous for drawings of deep dimensions on flat plates with extreme precision, was suffering from asymmetric eye aberration.
The researchers analyzed the trend of looking at the 6 works of Da Vinci, including Salvatore Mundi and John the Baptist, to show a presence with the orientation of the eyes to an external angle.
The team evaluated the state of the eye in the paintings by drawing circles on the cornea, iris and eyelids in each panel and measuring the distance between them.
Despite the different personalities in the art of Davinci, the artist has stated in his own writings that any work of art reflects the appearance of the artist.
The results showed one eye shift to 10.3 degrees outward in the case of relaxed vision, but the eyes become straight aligned in focus.
The researchers spoke specifically about Vinci's left eye, saying it was likely to have been affected by the condition.
An asymmetric eye divergence is a form of strabismus, affecting 1 percent of the world's population.
This situation results in difficulty in keeping the eyes aligned when seeing a fixed object.
This situation allowed Davinci to view the world from a different angle, and his strong understanding of the three-dimensional objects, which is evident in the subtle shading that is known in his paintings to give it a three-dimensional dimension.
Previous studies have pointed to the presence of this type of visual disorder in a large number of famous painters.
