The tear film that coats the front of the eye is very complex. The outer layer of the tear film is oily, produced by special glands (meibomian glands) within the eyelid, and it serves to prevent evaporation of the salt water middle layer. The inner layer is made of mucus secreted from cells onto the front surface of the eye and is important in helping the salt water layer spread evenly across the front of the eye.

Blinking spreads the tears across the front of the eye while also causing excess tears to be pushed out of a drainage system that leads from the inner corner of the eyelids into the nose. Anything that causes disruption of blinking, such as staring at a computer, the wind, and blowing fans, can compromise the tears.

A dry ocular surface can also result from medications like oral antihistamines and antidepressants, and medical conditions including arthritis or menopause (fluctuating hormones are the culprit here!). In some cases, poor tear quality and reduced tear quantity have no specific causes and are simply due to the aging process.

Dry eyes can range from a mild dry eye surface to a very disrupted, poor tear film. The person suffering from dry eyes might experience excessive tearing or eye-watering as the tear gland tries to resolve the dry eye condition itself, over-producing unwanted, low-quality tears to coat the eye. When the tear levels are low, the eye senses burning and grittiness. Itching and discomfort can also be signs of dry eyes. As the condition worsens, the eyes can become continually red, and vision can become blurry. Reflexive tears are released in an attempt to combat these issues but instead leave you with nothing but watery eyes.

Treatment for dry eye is necessary to restore a healthy ocular surface and treatments range from warm compresses to simple artificial tear drops or ointments to oral supplements containing Omega-3 fatty acids. In others, it can be treated with prescription eye drops that stimulate healthy tear production and fight inflammation. We will go into much more depth with all of these treatments in the upcoming lessons and let you know which ones we use in our clinic, but first, we want to go over what meibomian glands are and the massive role they play in how your eyes feel.
