What's the Weird Face We Make When We Touch Our Eyes

The video explores the phenomenon of 'mascara mouth,' where people open their mouths while applying mascara or inserting contact lenses. It discusses possible reasons, including nerve connections between the trigeminal and oculomotor nerves. The video also examines Marcus Gunn Syndrome, a rare genetic disorder, and the corneomandibular reflex, which involves involuntary jaw movement. Despite these connections, the exact cause of mascara mouth remains uncertain.

What is Marcus Gunn Syndrome?

• A condition where the jaw moves involuntarily when the cornea is touched
