1. Liver Heat
The Liver sends circulation to the eyes, however if there is too much Heat stuck in the Liver then the Heat will be sent up to the eyes as well. This will cause the body to have dry eyes as well as other symptoms such as burning sensation and red eyes, mild pain, red face, the body feels hot, emotional, insomnia, bloating and sluggish bowel movement with very smelly wind, or dizziness. These people usually don't like bright lights or being in front of the computer for too long. In certain cases, some people also combine the following diseases: hyperactive thyroid, high blood pressure, high cholesterol, Liver dysfunction.

2. Kidney & Liver Yin Weakness
Chinese Medicine consider that Kidney and Liver Yin provide moisture to the eyes to balance the eye function. Therefore, Kidney and Liver Yin weakness will cause eye dryness as well. The body will also experience the following symptoms: tired eyes, blurry eyes, tired body, dry skin, lower back and knee ache, frequent urination or thirsty during the night, poor memory, dry stool or hot flushes.

3. Exterior Wind
The Wind will attack the Urinary Bladder Channel which is part of the branch going to the eyes. These people may also experience the following symptoms: itchy eyes, red eyes, tears or headache. These people also usually have a lowered immune system, very easily affected by allergies such as hay fever or skin allergies.

Diet and Lifestyle to Improve your Dry Eyes

-- Everyday take some time to look at objects of the colour green (ie. trees and grass). In Chinese Medicine (5 elements), Green is associated with the Liver and can therefore benefit the eyes.
