Introduction
In Traditional Chinese Medicine (TCM), cataracts are understood as an eye condition associated with imbalances in the body's vital substances and organ systems, particularly the Liver, Kidneys, and Spleen.
Rather than viewing cataracts solely as a localized eye disorder, TCM considers the relationship between eye health and the body's overall balance of Qi, Blood, Yin, Yang, and Essence (Jing).
According to traditional Chinese medical theory, the eyes depend on adequate nourishment from the organ systems and the smooth circulation of Qi and Blood. When these functions become deficient or obstructed, visual disturbances may develop.
Common traditional patterns associated with cataract-related symptoms include Liver and Kidney Yin Deficiency, Spleen Qi Deficiency with Dampness, Liver Qi Stagnation, and Phlegm and Blood Stasis.
Understanding these patterns provides a foundation for individualized TCM approaches aimed at supporting eye health and overall well-being.
1. Understanding Cataracts in TCM
In traditional Chinese ophthalmology, cataracts are commonly associated with Yuan Yi Nei Zhang (圆翳内障), a traditional category describing progressive clouding within the eye and declining vision.
TCM considers cataract-related symptoms to be associated with insufficient nourishment of the eyes, impaired movement of Qi and Blood, and disturbances involving the Liver, Kidneys, and Spleen.
These organ systems play important roles in traditional Chinese medical theories of vision.
The Liver and Eye Health
In TCM, the Liver opens into the eyes and stores Blood.
Liver Blood and Liver Yin are traditionally considered essential for nourishing the eyes and maintaining clear vision.
When Liver Blood or Yin becomes deficient, symptoms may include:
-
Blurred vision
-
Dry eyes
-
Visual fatigue
-
Floaters
-
Dizziness
Liver Qi Stagnation may also interfere with the smooth circulation of Qi and Blood, contributing to visual discomfort and associated emotional symptoms.
The Kidneys and Essence (Jing)
The Kidneys store Essence, known as Jing, which is traditionally associated with growth, development, aging, and vitality.
In TCM, Kidney Essence and Kidney Yin help support the nourishment of the eyes.
As Kidney Essence gradually declines with age, the eyes may receive insufficient nourishment within the traditional theoretical framework.
Kidney Deficiency may be associated with:
-
Gradual deterioration of vision
-
Dryness of the eyes
-
Dizziness
-
Tinnitus
-
Lower back and knee weakness
The Spleen and the Production of Qi and Blood
The Spleen governs the transformation and transportation of nutrients and fluids.
It is also considered an important source of Qi and Blood production.
When Spleen Qi becomes deficient, the body's ability to transform and transport fluids may weaken.
In TCM, this may lead to Dampness and Phlegm accumulation, which can be associated with cloudy vision, fatigue, digestive weakness, and a sensation of heaviness.
The Relationship Between the Eyes and the Organ Systems
Traditional Chinese medicine emphasizes that the eyes are connected with the functioning of the entire body.
The Liver provides Blood nourishment, the Kidneys support Essence and Yin, and the Spleen contributes to the production and transportation of Qi and Blood.
When these systems remain balanced, they are traditionally believed to support healthy visual function.
When deficiencies or obstructions develop, various eye-related symptoms may occur.
2. Etiology and Pathogenesis
According to TCM theory, several factors may contribute to the development of patterns associated with cataracts.
Aging and Declining Kidney Essence
Aging is traditionally associated with the gradual decline of Kidney Essence and Yin.
As Essence becomes depleted, the nourishment of the eyes may weaken, contributing to reduced visual clarity within the TCM framework.
This is one of the principal traditional explanations for age-related visual decline.
Constitutional Weakness
Some individuals are considered to have weaker constitutional Essence or insufficient Liver and Kidney nourishment.
In traditional theory, these constitutional characteristics may increase susceptibility to visual weakness as a person ages.
Emotional Imbalance and Liver Qi Stagnation
The Liver governs the smooth movement of Qi.
Prolonged emotional stress, anger, frustration, and unresolved tension may contribute to Liver Qi Stagnation.
When Qi movement becomes obstructed, the traditional circulation of Qi and Blood to the eyes may be affected.
Overwork and Fatigue
Excessive physical or mental work, inadequate rest, and prolonged fatigue are traditionally believed to consume Qi and Blood.
Over time, this may contribute to Liver Blood Deficiency, Kidney Essence Deficiency, and reduced nourishment of the eyes.
Dietary Factors
TCM considers the Spleen particularly sensitive to dietary habits.
Excessive consumption of greasy, fried, heavy, or overly sweet foods is traditionally associated with the formation of Dampness and Phlegm.
When Dampness accumulates, it may interfere with the body's normal transformation and transportation functions.
Environmental Factors
Traditional Chinese medicine recognizes external influences such as Wind, Heat, and Dampness.
Excessive exposure to these environmental factors may disturb the body's balance and contribute to eye discomfort.
Protecting the eyes from excessive sunlight, wind, dust, and other environmental irritants is an important part of maintaining eye comfort.
Deficiency and Obstruction
A central principle in TCM is that cataract-related patterns may involve both deficiency and obstruction.
Deficiency patterns include:
-
Liver Blood Deficiency
-
Liver and Kidney Yin Deficiency
-
Kidney Essence Deficiency
-
Spleen Qi Deficiency
Obstruction patterns may include:
-
Liver Qi Stagnation
-
Dampness and Phlegm
-
Blood Stasis
These patterns may occur independently or together, requiring individualized differentiation.
3. Symptoms of Cataracts From a TCM Perspective
The symptoms associated with cataracts may vary depending on the underlying traditional pattern.
Common manifestations include the following.
Blurred or Cloudy Vision
Gradually blurred, hazy, or cloudy vision is a characteristic symptom associated with cataracts.
Within TCM pattern differentiation, visual cloudiness may be considered alongside signs of Essence Deficiency, insufficient nourishment, or Phlegm-Dampness.
Dry Eyes
Eye dryness is traditionally associated with Liver and Kidney Yin Deficiency or insufficient Blood nourishment.
Additional symptoms may include dry mouth, dizziness, and visual fatigue.
Floaters or Spots in Vision
Floaters or spots may be interpreted in TCM through patterns involving Liver Blood Deficiency, Kidney Deficiency, or Qi Stagnation.
However, floaters are not specific to cataracts. Sudden new floaters, flashes of light, or a shadow across the visual field require urgent eye evaluation.
Visual Fatigue
Eye fatigue after reading, prolonged concentration, or other visually demanding activities may be associated with insufficient Liver Blood or Yin in traditional theory.
Dull Complexion and General Fatigue
A dull complexion, tiredness, poor appetite, and reduced vitality may indicate Spleen Qi Deficiency.
Lower Back Weakness and Frequent Urination
Lower back weakness, knee discomfort, frequent urination, and reduced vitality may be associated with Kidney Deficiency.
Dizziness and Tinnitus
Dizziness and ringing in the ears may accompany Liver and Kidney Yin Deficiency or Kidney Essence Deficiency.
Difficulty Seeing Clearly at Night
Reduced visual clarity in dim lighting may occur with cataracts and may be considered alongside traditional patterns involving insufficient nourishment of the eyes.
These symptoms should be evaluated as part of the person's overall condition. Changes in vision should not be attributed to a TCM pattern without an appropriate eye examination.
4. Common TCM Diagnostic Patterns for Cataracts
Traditional Chinese Medicine emphasizes Bian Zheng (辨证), or pattern differentiation.
A TCM practitioner evaluates the patient's symptoms, constitution, tongue appearance, pulse characteristics, and overall health.
The following four patterns are commonly discussed in relation to cataract-associated symptoms.

Important Considerations for Herbal Medicine
These formulas and herbs have traditional uses related to eye health, but they have not been established as treatments that remove cataracts, restore the transparency of a clouded lens, or reliably prevent cataract progression.
Herbal formulas and concentrated extracts may interact with medications or be unsuitable for certain individuals.
They should be selected according to individual needs and used under appropriate professional guidance.
Acupuncture
Acupuncture is traditionally used to regulate Qi and Blood, harmonize the organ systems, and support general well-being.
In TCM eye-related care, acupuncture point selection may focus on the Liver, Kidneys, Spleen, and circulation of Qi and Blood.
Commonly discussed points include:
Liver 3 (LR3, Taichong — 太冲)
Traditionally used to soothe the Liver, regulate Qi, and address Liver Qi Stagnation.
Kidney 3 (KI3, Taixi — 太溪)
Traditionally used to nourish Kidney Yin, support Essence, and address Kidney Deficiency patterns.
Spleen 6 (SP6, Sanyinjiao — 三阴交)
Traditionally used to strengthen the Spleen, nourish Blood and Yin, and support the balance of the Liver, Spleen, and Kidneys.
Stomach 36 (ST36, Zusanli — 足三里)
Traditionally used to strengthen Spleen and Stomach Qi, support digestion, and promote overall vitality.
Gallbladder 20 (GB20, Fengchi — 风池)
Located at the base of the skull, this point is traditionally used to address Wind-related patterns and discomfort involving the head and eyes.
Acupuncture treatment should be individualized according to the patient's traditional pattern and physical condition.
Although acupuncture may be used as a complementary wellness practice, it has not been established as a method for reversing cataracts or restoring lens transparency.
Dietary Therapy
Dietary therapy is an important part of traditional Chinese health maintenance.
In TCM, food choices are used to support the Liver, Kidneys, and Spleen while maintaining the balance of Qi, Blood, Yin, and Yang.
A varied and nutritious diet can also support overall eye health.
Foods Traditionally Associated With Liver and Kidney Nourishment
Black Sesame Seeds
Traditionally associated with nourishing Liver and Kidney Essence.
Goji Berries
Commonly used in traditional dietary therapy to nourish Liver and Kidney Yin and support the eyes.
Blueberries and Other Berries
Provide nutrients and antioxidant compounds as part of a balanced diet.
Spinach and Dark Leafy Greens
Provide vitamins, minerals, and other nutrients important for overall health.
Carrots
Provide beta-carotene and other nutrients that support normal visual function.
Foods Traditionally Associated With Resolving Dampness
Barley
Traditionally associated with supporting the Spleen and addressing Dampness.
Millet
Commonly used in traditional dietary practices to support digestive balance.
Mushrooms
Provide nutrients and can be included as part of a varied, balanced diet.
Foods to Limit
Greasy and Fried Foods
Traditionally associated with Dampness and Phlegm accumulation when consumed excessively.
Excessively Sweet Foods
May contribute to poor dietary balance and are traditionally associated with impaired Spleen function.
Highly Processed Foods
Should be limited in favor of a varied diet containing nutrient-rich whole foods.
Dietary therapy should emphasize balance rather than unnecessary restrictions.
No specific food has been established as a treatment that clears an existing cataract.
Qi Gong and Eye Exercises
Qi Gong is a traditional mind-body practice combining gentle movement, controlled breathing, relaxation, and focused attention.
In TCM, Qi Gong is believed to support the smooth movement of Qi and promote harmony between the mind and body.
Traditional eye exercises may also be incorporated into daily wellness routines.
Gentle Eye Movements
Slowly moving the eyes in different directions may help provide a brief break from prolonged visual concentration.
Movements should remain comfortable and should not cause pain or strain.
Near-and-Far Focusing
Alternating attention between nearby and distant objects may help relieve discomfort associated with prolonged close-up activities.
Gentle Massage Around the Eyes
Light massage around the brow and surrounding facial areas may promote relaxation.
Avoid applying pressure directly to the eyeballs.
Relaxation and Breathing Exercises
Deep breathing, meditation, and gentle Qi Gong movements may help reduce stress and support general well-being.
These practices may improve comfort and relaxation, but they have not been shown to remove cataracts or reliably delay their progression.
6. Preventive Measures in TCM
Traditional Chinese Medicine emphasizes prevention through maintaining balance among the organ systems and supporting healthy daily habits.
The following approaches are commonly discussed in traditional eye-health maintenance.
Protecting the Eyes From Environmental Stress
Protecting the eyes from excessive sunlight, wind, dust, and other environmental irritants can help maintain eye comfort.
Wearing appropriate sunglasses outdoors may also help reduce ultraviolet exposure.
Maintaining a Balanced Diet
A varied diet containing leafy greens, berries, whole grains, seeds, and other nutrient-rich foods supports overall health.
In TCM, foods traditionally associated with Liver and Kidney nourishment may be incorporated according to individual needs.
Managing Emotional Stress
Since the Liver governs the smooth movement of Qi, emotional balance is considered important in TCM.
Meditation, Tai Chi, Qi Gong, and relaxation exercises may help manage stress and promote emotional well-being.
Avoiding Excessive Fatigue
Adequate rest and regular sleep are traditionally considered important for preserving Qi, Blood, and Essence.
Taking regular breaks during visually demanding activities may help reduce eye fatigue.
Maintaining Gentle Physical Activity
Regular walking, Tai Chi, Qi Gong, and other appropriate physical activities can support overall health and vitality.
Individualized Traditional Health Maintenance
Some individuals may choose acupuncture or herbal approaches as part of their broader wellness practices.
However, routine acupuncture or herbal supplementation has not been established as a reliable method of preventing cataracts.
Herbal products should be selected carefully, especially when other medical conditions or medications are involved.
Regular Eye Examinations
Because cataracts may develop gradually, regular eye examinations are important for identifying changes in vision and determining appropriate care.
Persistent blurred vision, glare, or difficulty with daily visual activities should be evaluated by a qualified eye-care professional.
7. Conclusion
In Traditional Chinese Medicine, cataracts are understood through the relationship between eye health and the body's overall balance, particularly involving the Liver, Kidneys, and Spleen.
Traditional patterns associated with cataract-related symptoms include Liver and Kidney Yin Deficiency, Spleen Qi Deficiency with Dampness, Liver Qi Stagnation, and Phlegm and Blood Stasis.
TCM emphasizes Bian Zheng Lun Zhi (辨证论治), or individualized treatment based on pattern differentiation.
Herbal medicine, acupuncture, dietary therapy, Qi Gong, eye exercises, and lifestyle modifications may be considered as complementary approaches to supporting eye comfort and general well-being.
The traditional goal is to nourish the eyes, support the organ systems, regulate Qi and Blood, and maintain harmony throughout the body.
However, these approaches have not been proven to reverse an established cataract or reliably prevent its progression. Appropriate eye examinations and established eye care remain essential.
The central principle of TCM is to support the eyes by addressing the individual's overall pattern of imbalance while maintaining harmony among Qi, Blood, Essence, and the organ systems.
By combining individualized traditional wellness practices with appropriate eye care and healthy daily habits, individuals can take a comprehensive approach to maintaining visual well-being and quality of life.
