How do I know if I have Dry Eye?
Dry eye can cause quite a few symptoms, anything from the eyes actually feeling dry to the eyes watering often, or having a burning, itchy, or irritated feeling. One of the most common symptoms is the eyes feeling gritty or like something is in your eye. Most people will often experience blurred vision since the tears, which comprise the outermost surface of the eye, are unstable.
Is there anything I can do to prevent DES?
Dry eye is multi-factorial, and each person’s dry eye is unique to them. To help prevent dry eye, make sure to consume 8 to 10 glasses of water per day to avoid dehydration. Some nutritional supplements, such as fish oil and flax seed oil, can contribute to a more stable tear layer.
Remember to blink regularly and take breaks often when on a computer, cell phone or when watching television. During times of the year when there is less humidity, a humidifier might be helpful to provide more moisture in the air.

Whether you want contact lenses or glasses, we make sure that you get both what looks good, but more importantly what works for your personal situation as well. We at Dennis N.
