Diminished night vision can be the consequence of several so-called “patterns of disharmony” in Chinese Medicine.
Chinese Medicine sees the body as a system, not a sum of isolated parts. A "pattern" is when the system's harmony is disrupted, leading to symptoms or signs that something is wrong (like diminished night vision here). It is similar to the concept of disease in Western Medicine but not quite: a Western disease can often be explained by several Chinese patterns and vice-versa.
A pattern often manifests itself in a combination of symptoms that, at first glance, do not seem necessarily related to each others. For instance here diminished night vision is often associated with dizziness, insomnia and blurred vision in the pattern “Liver Blood Deficiency”. As you will see below, we have in record four patterns that can cause diminished night vision.
Once identified, patterns are treated using medicinal herbs, acupuncture, and other therapies. In the case of diminished night vision we’ve identified four herbal formulas that may help treat patterns behind the symptom.
We’ve also selected below the five medicinal herbs that we think are most likely to help treat diminished night vision.
The four "patterns of disharmony" that can cause diminished night vision
In Chinese Medicine diminished night vision is a symptom for 4 patterns that we have on record. Below is a small explanation for each of them with links for more details.
The Liver is a so-called "Zang" Organ. Learn more about the Liver in Chinese Medicine
Liver Blood Deficiency
Pulse type(s): Choppy (Se), Fine (Xi)
Tongue color: Pale
The Liver stores Blood, that is the reason any Blood Deficiency often involves the Liver. This pattern has an impact on areas the Liver relates to, such as the tendons, eyes, nails and menstruation. It arises from the same causes of general Blood Deficiency, such as poor diet, hemorrhages or Kidney Qi or Essence Deficiency.
In addition to diminished night vision, other symptoms associated with Liver Blood Deficiency include dizziness, insomnia and blurred vision.
Liver Blood Deficiency is often treated with Si Wu Tang, a herbal formula made of 4 herbs (including Prepared Rehmannia - Shu Di huang - as a key herb). Si Wu Tang belongs to the category of "formulas that tonify blood", which might be why it is often recommended for this pattern. Its main action as a formula is: "Restores and nourishes Blood".

This is a type of empty Fire pattern arising out of Liver Blood Deficiency or Kidney Yin Deficiency.

It can be caused by excessive activity, overwork, 'burning the candle at both ends' without sufficient rest, and poor and irregular diet.
