What condition does entropion describe?

Entropion is a medical condition in which the rim of the eyelid turns inward, causing the eyelashes and skin to rub against the surface of the eye. This inward turning can lead to discomfort, irritation, and even damage to the cornea if left untreated. It is often associated with conditions that affect the eyelids, such as age-related changes or scarring. Understanding this condition is crucial for professionals in the beauty and health fields, as they may encounter clients with eyelid issues and need to be aware of how these conditions can impact eye health and beauty practices. The other options describe different eye-related conditions, but only the inward turning of the eyelid accurately captures what entropion specifically refers to.
