How Tears are Formed

All three components of the tear film are important and necessary for the eye to maintain a normal healthy environment. When the balance of the tear film components is not just right, or not enough tear film is being produced, dry eye can occur.

Many different types of glands and specialized cells are involved in producing the components of the tear film. When any or all of these glands are damaged or compromised, tear film production and quality are affected.
