Dry eye is a common condition that affects millions of Americans every year. It tends to be chronic and results from an incomplete tear film covering the surface of the eye. This occurs when your eyes do not produce enough tears or the tears evaporate too quickly. Symptoms of dry eye include blurry vision, fluctuation vision that often clears with a blink, tearing, itchiness, burning, discomfort, redness, light sensitivity and eye fatigue. Dry eye can be caused by a variety of reasons: allergies, dry air, environment, prolonged computer use, exposure to smoke, medications, contact lens wear and some medical conditions. Treatment initially includes over the counter moisturizing drops and can progress to other treatment options such as prescription medications like Restasis or Xiidra or punctal plugs. Having a comprehensive eye exam and discussing your symptoms, lifestyle and medical history can help determine what is causing your dry eye and determine the best course of action.
