Itchy eyes often have other symptoms, such as redness and irritation. Some people experience swollen eyelids and minor changes to vision. A doctor should examine itchy eyes, especially when symptoms have not improved within a few days, to determine the condition causing the itching. Knowing some of the possible causes may help people with itchy eyes find a solution, or encourage them to seek treatment.
Allergies
Allergies cause nasal and sinus symptoms, but allergies can also cause the eyes to itch. Pollens in the air, particularly in the spring, may push the itching into high gear, and itching may improve as the seasons change. Pet dander commonly causes eyes to itch. For pet allergies, frequent hand-washing after pet contact and avoiding touching the eyes may help prevent symptoms. Taking an oral antihistamine may relieve itching, but some people require an eye drop specifically for eye allergy symptoms. Doctors can prescribe allergy eye drops, but often recommend trying over-the-counter allergy drops first because non-prescription drops may be cheaper.
Infection
Eye infections such as conjunctivitis, commonly known as “pink eye,” cause itchy eyes. Eye infections frequently occur during cold season or from poor eye hygiene. Eye infections like “pink eye” can be transmitted easily from one person to another, which makes hand-washing extremely important. Many eye infections need a prescription eye drop in order to resolve the condition. Eye doctors will perform a brief exam of the front of the eye and determine which eye drop will work best. Most infections require an antibiotic drop, and patients should use the drops as directed. If a patient stops the drops when symptoms disappear, but before the full course of treatment, the infection may flare up.
Dry Eye
Dry eye results when the surface of the eye does not have enough moisture. The eyes may sting and itch, often turning red as well. Dry eye typically becomes a problem with age and hormonal changes in women. However, frequent computer use and constant reading also causes dry eye symptoms in many people. Artificial tears found in almost any drugstore will offer relief for most people. Doctors should examine eyes that do not improve with artificial tear use. If the doctor determines dry eye as the cause for the symptoms, he may recommend other options for dry eye, such as prescription drops to increase tear production.
