Why Are My Eyes Itchy?
Itchy eyes are a common problem, most often caused by allergies. Let's explore the reasons why your eyes might be itching.
-
Allergies: This is the most frequent culprit. Seasonal allergies (like pollen) or year-round allergies (like pet dander) are common triggers. This is supported by multiple sources, including the ACAAI (American College of Allergy, Asthma & Immunology) and healthdirect.gov.au. Irritants such as dust, smoke, or even certain cosmetics or contact lens solutions can mimic allergy symptoms.
-
Environmental Irritants: Dust, smoke, and other airborne pollutants can irritate the eyes, causing itching. Johns Hopkins Medicine suggests measures like closing windows and wearing sunglasses to avoid contact with irritants.
-
Eye Infections: Bacterial or viral infections can cause itchy, red, and watery eyes.
-
Blepharitis: This inflammation of the eyelids can lead to itching, burning, and a feeling of something in the eye. The National Eye Institute highlights these symptoms as characteristic of blepharitis.
-
Dry Eyes: Lack of sufficient lubrication can make your eyes feel itchy and uncomfortable.
-
Eyestrain: Prolonged screen time or other visual strain can contribute to itchy eyes. Medical News Today cites eyestrain as a cause of nighttime itchy eyes.
Understanding the Allergic Reaction
Allergic conjunctivitis is a common type of eye allergy. When an allergen (like pollen) comes into contact with your eyes, it triggers a reaction involving antibodies and mast cells in the conjunctiva (the membrane lining the eyelid and eye). This reaction leads to itching, redness, and tearing. The Mount Sinai website provides information on Allergic Conjunctivitis.
Solutions and Relief
While this information explains the why, it's crucial to see a doctor for diagnosis and treatment, especially if symptoms persist or worsen. Self-treatment options may include over-the-counter antihistamine eye drops or compresses. However, professional advice is always recommended.
