Trichomegaly is a condition in which the eyelashes are abnormally long,^[1] objectively defined as 12mm or greater in the central area and 8mm in the peripheral.^[2] The term was first used by H. Gray in 1944 in a publication in the Stanford Medical Bulletin,^[2] though he was only the third person to characterize the disorder; the first two reports were published in German in 1926 and 1931 by Reiter and Bab, respectively.^[3] Gray suggested the use of the term "movie lashes" to describe this condition, for long lashes were at the time being portrayed in film as a desirable characteristic in women.

The condition does not always present a medical issue and can sometimes be a benign familial or isolated trait. The presence of excessively long or lush lashes in healthy individuals is likely under-reported as it is an aesthetically pleasing facial feature and usually does not prompt diagnosis or treatment on its own.^[2]
