1. Common Causes of Itchy Corner of Eye

An itchy corner of the eye is a prevalent discomfort with various underlying causes. Understanding these reasons can aid in identifying the appropriate treatment and preventive measures. Let’s explore some of the most common culprits:

1.1. Allergies

Allergies are a frequent cause of eye itching, including the corners. Allergic reactions can be triggered by various allergens, such as pollen, pet dander, dust mites, and mold spores. When your eyes come into contact with these allergens, your body releases histamine, leading to inflammation and itching.

• Seasonal Allergies: These typically occur during specific times of the year, such as spring, summer, or fall, when pollen counts are high.

• Perennial Allergies: These can occur year-round and are often caused by indoor allergens like dust mites and pet dander.

Symptoms of allergic conjunctivitis include:
