Answer to identifying an eye condition

Entropion is a condition where the eyelid rolls inward, causing the periocular hair to rub against the cornea. It can affect any aspect of the upper or lower eyelids, but the lower, lateral aspect is most commonly affected. This constant friction leads to irritation and discomfort, and, if left untreated, can result in tearing, keratitis, and corneal ulcers.
