How common is distichiasis in humans?

Distichiasis is observed in 94% of affected individuals. The degree of distichiasis can range from a single cilia to a full set of extra eyelashes. 75% of affected individuals have other ocular findings including corneal irritation, recurrent conjunctivitis, and photophobia.

Are double row eyelashes rare?
