Itchy eyes are usually caused by allergies, which can be irritating. Itchiness can also be caused by pink eye, eye strain, or eye fatigue. If you are in a lot of pain or suspect an infection, see your doctor as soon as possible.
Eyestrain is another possible cause of burning, itchy eyes. Common causes of eyestrain include looking at digital screens all day or driving long distances.
