Which condition is the inversion of the edge of an eyelid?

The condition in which the edge of an eyelid turns inward is known as "entropion." This can lead to irritation, discomfort, and potential damage to the cornea due to the eyelashes rubbing against the eye. Entropion can occur due to age-related changes, scarring, or congenital factors. Treatment may involve surgical correction to restore the eyelid's normal position.
