Introduction
Itching of the eyes after staying up late may be caused by poor blood circulation. Conjunctivitis cannot be ruled out as a potential cause. Prolonged sleep deprivation and chronic late-night activity can impair normal blood circulation around the eyes, leading to conjunctival congestion and resulting in itching at the inner or outer canthus. Local warm compresses or gentle massage to promote ocular blood circulation may help alleviate this symptom.

Staying up late poses significant harm to people’s health and may even trigger various diseases. So, what causes itchy eyes after staying up late?

What Causes Itchy Eyes After Staying Up Late?

Itchy eyes following sleep deprivation may result from impaired blood circulation. Conjunctivitis cannot be ruled out as a possible cause. Prolonged熬夜 and chronic sleep deprivation disrupt normal blood circulation around the eyes, leading to conjunctival congestion and subsequently causing itching at the inner or outer corners of the eyes. Local warm compresses or gentle massage can help improve circulation and alleviate this itching. Additionally, excessive eye strain—leading to corneal damage and secondary conjunctivitis—may increase ocular secretions and provoke itching. In such cases, ofloxacin eye drops or erythromycin eye ointment may be used to relieve symptoms. In daily life, use your eyes reasonably, perform eye exercises regularly, and reduce ocular strain to minimize damage.

If ocular inflammation is present, certain dietary restrictions apply—for example, avoid spicy, stimulating foods and seafood such as fish and shrimp, as these may exacerbate inflammation and impede recovery. Smoking and alcohol consumption should also be strictly avoided during active illness. Furthermore, adhere closely to your physician’s instructions regarding the application of prescribed eye drops or ointments. Prioritize adequate rest for your eyes, avoid overuse, and limit screen time on smartphones, computers, and other electronic devices. Ensure sufficient sleep to bolster your immune system.

When experiencing dryness and itching at the eye corners, prompt medical evaluation and treatment are essential to prevent disease progression. We hope this information proves helpful.
