Itchy corners of the eye may be caused by不良 habits, trauma, environmental factors, keratitis, allergic conjunctivitis, blepharitis, and other conditions.

Non-disease factors may also lead to itchy corners of the eye, such as traumatic factors like injuries or foreign bodies. Unhealthy lifestyle habits, such as prolonged use of electronic devices and staying up late, may also cause itching at the corners of the eyes. Chemical factors, such as certain eye drops or cosmetics accidentally getting into the eyes, may also lead to this condition. Environmental factors, such as being in a dry or dusty environment for a prolonged period, may also cause itching.

Allergic conjunctivitis is one of the most common causes, which may involve a reaction to allergens such as pollen, dust mites, pet dander, or cosmetics. Inflammation of the skin along the eyelid margins, often associated with dysfunction of the oil glands, can also cause itchiness in the corners of the eyes.

If itchy corners of the eye are accompanied by symptoms such as redness, increased discharge, or vision loss, it is recommended to seek timely medical attention for accurate diagnosis and treatment. Avoid rubbing the eyes to prevent worsening symptoms or causing infections. Maintaining eye hygiene and using eye drops or ointments recommended by a doctor can help alleviate symptoms.
