Everyone gets foreign material like dust or eyelashes in their eyes from time to time. Entropion is the feeling of something in your eye most, if not all, of the time. It is actually the eyelid or eyelash that is affecting the inner membranes.
Entropion occurs when the eyelid turns or folds inward toward your eye. When this occurs, the eyelashes also turn in and rub against the surface of the eyeball. This scratchy sensation imitates the feeling of something in the eye. Depending on the person, the issue can be constant, or occur when blinking or tightly closing the eyes.
