What causes itching around the eyes?
Itching around the eyes can be attributed to two main causes: non-disease factors and disease-related factors. Common disease-related causes include allergies, keratitis, and others.
I. Non-disease Factors
This may occur when foreign substances such as dust or hair enter the eye, irritating the surface of the eyeball.
II. Disease-related Factors
1. Allergies
Exposure to allergens such as pollen or house dust mites, or using substandard skincare products, may trigger allergic reactions in the skin around the eyes.
2. Keratitis
Keratitis may result from prolonged use of contaminated contact lenses, corneal injuries, or infections caused by pathogenic microorganisms such as tuberculosis bacteria, bacteria, or viruses. Increased eye discharge associated with keratitis can irritate the surrounding area.
In addition, conditions such as dry eye syndrome may also cause itching. Timely differential diagnosis is recommended.
