An ingrown eyelash (trichiasis) is a common eye problem that causes eyelashes to grow abnormally.

Instead of growing out, ingrown eyelashes grow inward toward the eye.

If an ingrown eyelash is not treated, it can even damage your eye.

Constant irritation can lead to corneal abrasion.

If the condition is untreated or chronic, inflammation and vision loss can happen.

When this happens, the hair follicles can get misdirected and trichiasis can develop.
