In the world of Traditional Chinese Medicine, the liver energy flows upward into the eyes. When this energy is flowing smoothly and working as it should, your vision is clear and sharp, you have efficient night vision and the eyes are bright and well-lubricated.
When out of balance, the liver can generate heat that rises upward. This heat can manifest in dry eyes, itchy eyes or eyes that are red and irritated. Think about how red one’s eyes can get after a night of drinking. Alcohol adds heat to the liver, which in turn rises upward and creates hot, red eyes. The facial flushing you see after a night of imbibing is also indicative of this heat.
When the liver blood is deficient, you will see symptoms of dryness throughout the body, particularly in the eyes. Dry, scratchy eyes are a sign of liver blood deficiency, and floaters (those little black spots that can appear in the periphery of your vision) are also indicative of this deficiency.
When liver blood deficiency becomes more pronounced, patients can develop something we acupuncturists refer to as “Internal Wind.” Wind manifests as symptoms of shaking, tics, tremors or issues such as rashes that move around from place to place within the body. You know that annoying eye twitch you get that you are convinced the world can see, even though everyone tells you they don’t notice it? Those tics are a sign the body is deficient in energy, and wind has developed to shake things up. Internal wind can also show up as issues that itch, such as dry, itchy eyes.
The kidney plays a role in keeping the body well-oiled and lubricated. If the kidney yin is lacking, you might experience dry, creaky joints, dry skin and eyes.
