Styes

Styes are tender eyelid bumps that can develop when an oil gland or eyelash follicle becomes blocked, irritated, or inflamed. While a single stye can happen occasionally, recurring styes may point to a deeper eyelid environment issue, especially when they appear with itchy eyelids, lash-line crusting, redness, collarettes, cylindrical dandruff, dry eye symptoms, or chronic lid margin irritation. In Demodex blepharitis, mite-related buildup around the lash follicles may contribute to inflammation and gland congestion, making the eyelids more prone to irritation. This section explains how styes may connect with Demodex-related eyelid concerns and what lash-line clues to look for.
