Dr. Wang Shuai
Redness in the corner of the eye may have various causes, which can be summarized as follows:
1. Conjunctivitis: Caused by poor eye hygiene or excessive eye strain, often accompanied by conjunctival congestion and increased eye discharge.
2. Allergic conjunctivitis: Triggered by exposure to allergens, characterized by redness, pus discharge, tearing, and skin rashes.
3. Stye (hordeolum): Usually caused by bacterial infection, with symptoms including eyelid swelling, pain, and a firm lump.
4. Chronic sleep deprivation: Lack of sufficient sleep may lead to eye congestion and mild redness in the eye corners.
5. Eye strain: Prolonged use of the eyes, especially staring at screens, may cause eye fatigue and subsequent ocular congestion.
6. Environmental factors: Dry environments—dry air can cause eye discomfort and lead to redness in the corners of the eyes.
