What does entropion cause?

Entropion is a medical condition characterized by the inward folding of the eyelid towards the eyeball. This misalignment can lead to the eyelashes rubbing against the cornea and conjunctiva, which can cause discomfort, irritation, and potential damage to the eye's surface. The primary consequence of entropion is indeed the eyelid folding inward, affecting the overall health of the eye and prompting symptoms that may require medical attention or surgical correction.

The other options describe symptoms or conditions that may be associated with various eye disorders, but they do not specifically define the primary physical manifestation of entropion itself. Therefore, recognizing entropion's defining feature aids in understanding not only the condition but also its implications for eye health.
