What is (are) Dry Eye ?
Dry eye occurs when the eye does not produce tears properly, or when the tears are of poor quality and dry up quickly. The eyes need tears for overall eye health and clear vision. Dry eye can last a short time or it can be an ongoing condition. It can include a variety of symptoms, such as discomfort and pain. Your eyes may sting and burn and you may have redness and a sandy or gritty feeling, as if something is in your eye. You may have blurry vision and you may feel eye fatigue. Having dry eyes can make it harder to do some activities, such as using a computer or reading for a long period of time, and it can make it hard to be in dry places, such as on an airplane.
