What is Dry Eye Disease?

In a healthy eye, there is a layer of liquid that is always present called the tear film. This tear film is composed of a watery layer, an oil layer and a mucus layer. Together these three elements work together to keep the eye coated in a layer of tears.

When one or more of these elements is not working as it should, the eye is no longer covered in the proper layer of tears. This causes the eye to become dry and is called Dry Eye Disease.

What are the symptoms of Dry Eye Disease?

Dry Eye Disease has many uncomfortable symptoms. They can include:

  • Burning or Stinging Eyes
  • Gritty or dry sensation in the eyes
  • Red Eyes
  • Mucus in the eyes

The symptoms of dry eye are numerous, and can range from annoying to nearly debilitating.
