What is Dry Eye?
Every time you blink, a thin layer of tears is spread across the cornea. This thin layer of moisture, known as the tear film, forms a protective coat that lubricates your eyes and washes away any debris that might harm or obscure your vision. 1
Dry eye occurs when the tear glands stop making enough tears, produce poor-quality tears, or the tears evaporate too quickly, causing your eyes to feel dry and irritated.2,3
Millions of people suffer from dry eye, making it one of the most common conditions reported to eye doctors today. Although there is no cure for the condition, there are a variety of treatments available to soothe its symptoms and help you feel more comfortable.4
