Leonardo da Vinci may have had eye disorder

The video discusses exotropia, a condition where one eye turns outward, potentially affecting 3D vision. Christopher Tyler, a visual neuroscientist, studied da Vinci's art and found evidence suggesting da Vinci may have had intermittent exotropia. This condition could have allowed da Vinci to switch between 3D and 2D vision, possibly giving him an artistic edge. Exotropia can be treated with glasses, patches, or surgery.

What is exotropia?

• A condition where one eye turns slightly outward

• A condition where one eye turns slightly downward

• A condition where both eyes turn inward

• A condition where both eyes turn upward

• Leonardo da Vinci

• Christopher Tyler

• Science News

• City, University of London

How many pieces of art did Tyler analyze for signs of exotropia?

• Four

• Five

• Six

• Seven

What are some treatment options for exotropia?

• Meditation and relaxation techniques

• Special glasses, eye patches, or surgery

• Medication and physical therapy

• Dietary changes and exercise

How might da Vinci's control over his exotropia have benefited his art?
