Introduction
1. Frequent use of eye makeup: Many cosmetic products contain chemical ingredients, and wearing makeup for over 8 hours can easily damage the eyes.
2. Prolonged use of electronic devices: The radiation emitted by these devices when viewed up close can cause ocular discomfort; extended exposure may lead to dryness, inflammation, and itching.
3. Abnormal eyelashes: Misdirected or ingrown eyelashes can irritate the cornea, resulting in generalized ocular itching.
Itchiness at the inner or outer corners of the eyes is often overlooked—many people assume it’s trivial and poses no threat to their overall health. In reality, however, failing to address this symptom promptly may exacerbate the itchiness and even lead to redness and swelling of the eyes. These manifestations typically stem from inflammation of the eye corners or allergic reactions affecting the eyes. Therefore, identifying the underlying cause is essential before initiating appropriate treatment. Below, we explain the common causes of itchiness at the eye corners.
What Causes Itchiness at the Eye Corners?
1. Frequent Use of Eye Makeup
Many women use cosmetics to enhance their appearance, especially around the eyes. However, numerous cosmetic products contain chemical ingredients that can irritate the eyes—particularly when worn for extended periods (e.g., over eight hours)—potentially causing ocular discomfort and itchiness. Consider whether you regularly wear eye makeup and for how long.
2. Prolonged Use of Electronic Devices
Extended screen time—especially with computers and other digital devices—can also trigger itchiness at the eye corners. The radiation and blue light emitted by these devices may disrupt normal ocular function, leading over time to symptoms such as dryness, inflammation, and itching.
3. Abnormal Eyelashes
Abnormal eyelash growth—such as trichiasis (in-turned lashes) or distichiasis (extra row of lashes)—can cause mechanical irritation to the cornea or conjunctiva, resulting in persistent itchiness at the eye corners.
4. Conjunctivitis
Bacterial (or sometimes viral or allergic) conjunctivitis induces inflammation, manifesting as itchiness, redness, and swelling at the eye corners. During active infection, many patients experience intense, unbearable ocular itching.
The above outlines the primary causes of itchiness at the eye corners. We hope this information proves helpful to you.
