Dry Eye Disease is a common condition that affects about 20% of the population.
Affecting people of all ages with varying severity of ocular signs and symptoms, Dry Eye Disease is caused by a tear film that is in distress.
Your tear film is composed of 3 layers:
- Mucoid layer: a thin layer of mucous that adheres to the eye.
- Aqueous layer: the thickest layer of your tear film. This watery component represents 90% of your tear film.
- Oily layer: a thin layer of oil that lays on the outermost layer of your tear film.
The balance and composition of these three layers are very delicate. The imbalance of the components is the basis of a “tear film in distress.”
