Causes of itchy eyes
Itchy eyes can have a number of different causes, and sometimes it’s just temporary irritation, while other times it can be a sign of a health problem that needs treatment. Here are some of the most common causes of itchy eyes:
Dust and pollution
Dust, exhaust fumes or chemicals in the air can irritate the eyes, causing itching, tearing or burning, especially in large cities with high pollution.
Allergies to pollen, animal hair, and dust mites
Allergens such as pollen, animal dander and dust mites can cause the immune system to overreact, resulting in itchy, red and watery eyes.
Dry eyes or prolonged eye strain
Staring at a computer or phone screen for long periods of time can cause you to blink less, leading to dry, itchy eyes. People who wear contact lenses for long periods of time may also experience this problem.
Eye infections
If itchy eyes are accompanied by green or yellow mucus, it could be due to an infection, such as conjunctivitis, which often causes redness, swelling, and pain. You should seek immediate medical attention.
