Itchy eyes are a common discomfort that can occur due to various reasons. They may be caused by allergies, such as pollen or pet dander, which trigger an immune response. Other factors include dry air, smoke, or exposure to irritants like dust and chemicals. People often experience itchy eyes alongside other symptoms, such as redness, watering, or swelling. Over-the-counter antihistamines or artificial tears can help relieve the discomfort. If symptoms persist, it may be advisable to consult a healthcare professional for further evaluation and treatment options.
