Turning in results in scratching of the cornea with the turned in lashes, resulting in irritation, foreign body sensation and redness of the eye.
The eye can be temporarily relieved by epilation or plucking of the lashes by an eye doctor. But the irritation resumes when the hair grows back. Long term irritation can cause corneal wound and ulcers which are difficult to treat.
