Dry eyes are often caused by an imbalance in the tear film on the surface of the eye. This causes irritation that leads to inflammation and damage to the cornea. The most common symptom is blurred vision. Other symptoms include burning, itching, redness, and sensitivity to light.
What Causes Dry Eye Syndrome?
There are several different types of dry eye syndrome. One type is called keratoconjunctivitis sicca (KCS). KCS occurs when there’s not enough moisture in the tears. Another type is called evaporative dry eye. In this case, the body produces too much mucus, causing the eyes to feel dry. A third type is called allergic dry eye. Allergic dry eye occurs when the immune system attacks the cells that line the eyelids and cause them to produce extra mucus.
Symptoms of Dry Eye Syndrome
If you’re suffering from any of these symptoms, it might mean you have dry eye syndrome. You should see an ophthalmologist as soon as possible. They’ll check your eyes with a slit lamp and do tests to determine whether you have dry eye.
There are several treatments available for dry eye syndrome. These include artificial tears, lubricants, and medications. Artificial tears are usually prescribed by your doctor. Lubricating drops help keep your eyes moist and comfortable. Medications such as antihistamines and antidepressants can also help relieve some of the symptoms associated with dry eye syndrome.
