Itchiness of Eye
Eye itchiness is a common symptom that can range from mild irritation to intense discomfort affecting daily activities. While often caused by allergies or dry eyes, persistent itching may indicate infections or other eye conditions. Understanding the triggers and proper management helps prevent complications from excessive rubbing and provides effective relief.
⚠️ Seek Immediate Medical Care For:
- Severe eye pain with itching
- Sudden vision changes or loss
- Light sensitivity with severe itching
- Eye discharge with fever
- Swelling that closes the eye
- Itching after chemical exposure
- Signs of severe infection
- Itching with eye injury
Definition and Overview
Eye itchiness, medically known as ocular pruritus, is an uncomfortable sensation that creates an urge to rub or scratch the eyes. This symptom results from irritation of nerve endings in the conjunctiva (the clear membrane covering the white part of the eye) or surrounding tissues. The itching can affect the eyeball itself, eyelids, or corners of the eyes.
While rubbing provides temporary relief, it often worsens the condition by releasing more histamines and potentially introducing bacteria. Chronic eye rubbing can lead to complications including keratoconus (corneal thinning), increased risk of infection, and worsening of underlying conditions. Identifying and addressing the root cause is essential for effective treatment.
