Dry eye is a disorder of the tear film due to tear deficiency or excessive evaporation.
The most common reasons for dry eye include age, digital device use, contact lens wear, and the use of medication. The most common symptoms are itching, inconsistently blurry vision, redness, watery eyes, grittiness, burning, and eye fatigue.
A dry eye diagnosis is usually made from a patient’s dry eye symptoms, and the signs present on the front of the eye, confirmed through specific tests. Dry eye disease can be frustrating for both the patient and doctor because it’s considered chronic. The symptoms don’t always match the appearance of the eye that your eye doctor sees. It may require life-long treatment.
