Color Blindness
色盲 · sè mángColor blindness in TCM is rarely just about the eyes - it's a window into deeper imbalances in the Liver, Kidneys, and Spleen. While congenital cases may not fully reverse, many acquired or worsening color vision changes can improve with constitutional treatment within 3-6 months.

Color blindness isn't a single condition in TCM - it's a family of five distinct patterns, each with its own cause and its own treatment. Most cases, especially congenital ones, trace back to a deep-rooted deficiency of Liver Blood and Kidney Essence that fails to nourish the eyes. Other patterns may involve excess heat, dampness, or blood stagnation that clouds or disturbs vision. This means that even when two people share the same Western diagnosis, their TCM treatment plans can look completely different.
Color blindness, or color vision deficiency, is the reduced ability to distinguish between certain colors, most commonly red and green. The vast majority of cases are inherited and present from birth, caused by genetic mutations that affect the photopigments in the cone cells of the retina. It is far more common in men than women.
Acquired color vision loss can develop later in life due to eye diseases (such as glaucoma or macular degeneration), certain medications, chemical exposure, or as a part of the aging process. Diagnosis is typically made with standardized color plate tests like the Ishihara test. Conventional medicine offers no cure for the congenital form, though specially tinted lenses or digital tools may help some people distinguish colors more easily.
Conventional treatments
For congenital color blindness, there is no medical treatment that can restore normal color vision. Some people find that special glasses (such as EnChroma lenses) or contact lenses can enhance color contrast, but they do not work for everyone and are not a cure. Smartphone apps and screen filters can also assist with color identification. When color vision loss is acquired, treatment focuses on addressing the underlying condition - for example, managing glaucoma or changing a medication that is causing the side effect.
Where conventional treatment falls short
The conventional approach largely accepts congenital color blindness as fixed, offering no therapy to strengthen the visual system from within. For acquired cases, once the underlying trigger is removed, recovery is often assumed to be complete or impossible, with little attention paid to the body's own capacity for repair. This is where TCM offers a different perspective: by looking at the whole constitution and the quality of the blood and essence that nourish the eyes, it provides a path for those who wish to support their vision proactively, even when a complete cure is not promised.
How TCM understands color blindness
In TCM, the ability to perceive color depends on the nourishment and clarity of the eyes, which are directly linked to the Liver, Kidneys, and Spleen. The Liver stores Blood and opens into the eyes; when Liver Blood is abundant, the eyes are moist and vision is sharp. The Kidneys store Essence (Jing), the foundational substance that generates marrow and fills the brain, ultimately supporting the retina and optic nerve. The Spleen transforms food into clear Qi that rises to brighten the senses.
Congenital color blindness is almost always seen as a weakness in the prenatal Jing, manifesting as Liver Blood and Kidney Essence Deficiency. The eyes simply don't receive enough nourishment from the start. Acquired or worsening color vision loss, on the other hand, often involves a secondary factor: Liver Fire flaring upward and disturbing the eyes, Dampness and Phlegm clouding the clear orifices, or Blood Stagnation choking the tiny vessels that feed the retina.
This is why TCM doesn't treat all color blindness the same way. A person with dry eyes, weak knees, and a pale tongue needs nourishment. Another with red, burning eyes, a bitter taste, and a wiry pulse needs heat cleared. By identifying the underlying pattern, treatment can be tailored to not just the symptom but the whole person.
「五脏六腑之精气，皆上注于目而为之精。」
"The essential qi of the five zang and six fu organs all pour upward into the eyes to create their essence."
How a TCM practitioner diagnoses color blindness
Inside the consultation
A TCM practitioner begins by asking whether the color vision difficulty has been present since birth or developed later. Congenital color blindness almost always points to a deep-rooted deficiency of Liver Blood and Kidney Essence, the fundamental substances that nourish the eyes. The person may also report dry eyes, blurred vision, or night blindness, and the tongue is often pale with a thin coating while the pulse feels thin and weak.
If the problem appeared suddenly or worsens in episodes, the practitioner looks for signs of Liver Fire Blazing. This pattern brings heat and agitation: the eyes may feel red, painful, and dry, and the person is often irritable with a bitter taste in the mouth. The tongue is red with a yellow coating and the pulse is rapid and wiry, confirming that excess heat is flaring upward to disturb vision.
When the eyes feel heavy or vision seems cloudy, the focus shifts to dampness. In Spleen Deficiency with Dampness, poor digestion and fatigue accompany a sensation of ocular heaviness, a pale and swollen tongue with a greasy coat, and a weak, slippery pulse. If Damp-Heat settles in the Liver Channel instead, the eyes are more likely to be red, swollen, and sticky, with a red tongue bearing a thick yellow greasy coat and a rapid, slippery pulse.
Chronic, unchanging color vision loss with a history of eye injury or poor circulation may indicate Blood Stagnation in the delicate vessels of the eye. Here the tongue may show dark spots or a purplish hue, and the pulse feels choppy or deep. The key clue is that the deficit remains fixed rather than fluctuating, pointing to a physical obstruction rather than a functional weakness or acute flare-up.
<<TCM Patterns for Color Blindness
In TCM, the aim is to address the root cause, not just the symptom — it calls that root cause a “pattern.” The same color blindness can come from several different patterns, each treated differently. The quickest way to find yours is the quiz below.

Which signs match your experience?
It is very common to recognize pieces of yourself in more than one pattern, especially if your color perception has changed over time. For example, a person with a lifelong mild deficiency may experience a temporary worsening during a period of high stress and anger, mixing signs of Liver Blood and Kidney Essence Deficiency with Liver Fire. The patterns are not rigid boxes - they describe dynamic processes in the body.
To narrow things down, pay attention to which symptoms dominate and what makes them better or worse. Dry, tired eyes that improve with rest and warm compresses lean toward deficiency, while red, irritated eyes that flare up after alcohol or spicy food point toward heat or damp-heat. A sensation of heaviness and foggy vision after eating suggests Spleen weakness and dampness.
Because tongue and pulse examination provides decisive information that you cannot assess at home, a professional TCM diagnosis is the safest next step, especially if your color vision has changed noticeably or is accompanied by pain, sudden vision loss, or persistent redness. A practitioner can differentiate between overlapping patterns and create a personalized treatment plan that addresses the root cause rather than just the symptom.

Formulas traditionally used for color blindness
5 formulas across the patterns above. The right one depends on your pattern — start with the quiz if you're unsure which fits.
A classical formula that nourishes the Liver and Kidneys to support eye health and clear vision. It is used for blurred vision, dry eyes, sensitivity to light, excessive tearing in wind, dizziness, and ringing in the ears caused by Liver and Kidney Yin deficiency. Built on the famous Liu Wei Di Huang Wan (Six-Ingredient Rehmannia Pill) with the addition of goji berry and chrysanthemum flower for their vision-supporting properties.
A classical formula designed to deeply nourish Kidney Yin and replenish the body's vital essence and marrow. It is used when there is significant depletion of the body's fundamental nourishing fluids and substances, leading to symptoms such as dizziness, lower back and knee weakness, night sweats, dry mouth and throat, and a general state of thinning or exhaustion. Unlike milder Yin-nourishing formulas, Zuo Gui Wan is a purely replenishing formula without any draining ingredients, making it suitable for more severe deficiency.
A powerful cooling formula used to address conditions caused by excess heat and dampness in the Liver and Gallbladder systems. It is commonly used for red, painful eyes, headaches, ear problems, irritability, urinary difficulties, and skin conditions like shingles, particularly when accompanied by a bitter taste in the mouth, dark urine, and a feeling of heat or inflammation along the sides of the body or in the genital area.
A gentle classical formula that strengthens weak digestion, clears excess internal dampness, and stops diarrhea. It is commonly used for people experiencing chronic loose stools, bloating, poor appetite, fatigue, and a sallow complexion caused by a weakened digestive system. By supporting the Spleen and Stomach, it also indirectly benefits the Lungs, helping with shortness of breath and chronic cough with thin white phlegm.
A classical formula designed to improve blood circulation in the head and face, used for stubborn headaches, hair loss, hearing difficulties, skin discolorations, and other problems caused by stagnant blood obstructing the sensory organs. It works by powerfully moving blood and opening the body's orifices (eyes, ears, nose, mouth) in the upper body.
Congenital deficiency patterns require patience; improvement is gradual and may be subtle, with some people noticing better contrast or less eye strain after 3-6 months of consistent treatment. Acquired patterns like Liver Fire or Damp-Heat can respond more quickly, sometimes within weeks once the excess is cleared. Blood Stagnation patterns often need several months to unblock the microcirculation. In all cases, TCM aims to prevent further decline and support the best possible visual function.
Treatment principles
Across all patterns, the treatment of color blindness in TCM shares a common goal: to restore the free flow of clear Qi and blood to the eyes. This always involves addressing the Liver and Kidneys, the two organs most directly responsible for vision. From there, the strategy diverges.
For deficiency patterns, the emphasis is on nourishing and building - using formulas like Qi Ju Di Huang Wan or Zuo Gui Wan to replenish Liver Blood and Kidney Essence. For excess patterns, the focus shifts to clearing - draining Liver Fire with Long Dan Xie Gan Tang, transforming Dampness with Shen Ling Bai Zhu San, or invigorating Blood with Tong Qiao Huo Xue Tang.
Acupuncture points are chosen to reinforce the herbal strategy: local points around the eyes (like Jingming BL-1) to stimulate local circulation, and distal points on the Liver, Kidney, and Spleen channels (like Taichong LR-3, Taixi KI-3, and Zusanli ST-36) to correct the root imbalance. Many patients present with mixed patterns, and treatment is adjusted over time as the underlying landscape shifts.
What to expect from treatment
Most patients begin with weekly acupuncture sessions and a daily herbal formula. Progress is usually assessed after about 4-6 weeks, though a full course of treatment for chronic or congenital conditions often lasts 3-6 months or longer. The first changes are often subtle: less eye fatigue, less dryness, perhaps a sense that colors seem slightly brighter or more distinct. Dramatic, sudden reversal of color blindness is rare, but gradual, meaningful improvement in visual comfort and function is a realistic goal.
If your pattern is primarily excess (Liver Fire or Damp-Heat), you may notice a quicker response as the acute irritation subsides. Deficiency and Blood Stagnation patterns take more time. Your practitioner will likely recommend periodic breaks from herbs and may teach you acupressure points to use at home between sessions.
General dietary guidance
To support eye health from a TCM perspective, focus on warm, nourishing, and easily digestible foods. Favor goji berries, black sesame seeds, walnuts, dark leafy greens (like spinach and kale), carrots, blueberries, and moderate amounts of high-quality animal proteins such as bone broth and eggs. These foods help build Liver Blood and Kidney Essence.
Avoid or minimize cold, raw foods, greasy or deep-fried items, alcohol, and excessive spicy heat (like chili peppers), as these can injure the Spleen and generate Dampness or Fire that cloud the eyes. Staying well-hydrated with warm water or mild herbal teas also helps keep the channels clear.
Combining TCM with conventional treatment
TCM treatment for color blindness can be safely combined with conventional eye care. There are no known adverse interactions between the herbal formulas commonly used for this condition and standard medications.
However, if you are taking any prescription drugs - particularly those that affect the liver or kidneys, or blood-thinning medications - always inform both your TCM practitioner and your prescribing doctor. Herbs that invigorate blood (such as Dan Shen or Chuan Xiong) may have mild anticoagulant effects and should be monitored if you are on warfarin or similar drugs. Never stop or adjust your prescribed medications without medical supervision.

Safety & special considerations
-
Sudden loss of color vision in one or both eyes — Especially if it happens within minutes or hours - could indicate a retinal artery occlusion or stroke.
-
Color vision change accompanied by severe eye pain or headache — May signal acute glaucoma or other serious eye conditions requiring immediate attention.
-
New onset of flashes of light, floaters, or a curtain-like shadow over your vision — These are classic signs of retinal detachment, a medical emergency.
-
Color vision loss following a head injury — Even a mild concussion can sometimes damage the visual pathways; prompt evaluation is essential.
-
Sudden change in color perception along with weakness, numbness, or difficulty speaking — These could be signs of a stroke or transient ischemic attack (TIA).
Audience-specific guidance — open what applies to you
Congenital color blindness is often diagnosed in childhood, and in TCM it is viewed as an inherited weakness of Kidney Essence and Liver Blood. Children may not articulate their color vision difficulty, so parents might notice it when the child struggles to name colors or shows disinterest in coloring activities. The tongue is typically pale and thin, and the pulse is fine and weak.
Treatment focuses on gentle dietary therapy and mild herbal formulas like Qi Ju Di Huang Wan in pediatric dosages (one-quarter to one-half of adult dose), with acupuncture rarely used unless the child is older. Nourishing foods such as goji berries, black sesame, and bone broths are encouraged to support the postnatal Essence and Blood.
In the elderly, color vision loss often accompanies other age-related eye conditions such as cataracts or macular degeneration, and it is almost always rooted in Liver and Kidney Deficiency with possible Blood Stagnation or Phlegm. The treatment principle is to nourish the Liver and Kidneys while gently moving blood and transforming phlegm. Herbal dosages should be lower, typically two-thirds of the standard adult dose, to avoid burdening a weakened digestive system.
Acupuncture points like Ganshu BL-18 and Shenshu BL-23 are well-tolerated, but caution is needed with strong blood-moving formulas. The treatment timeline is longer, and improvement is gradual, reflecting the deep depletion that accumulates with age.
Evidence & references
The evidence base for TCM treatment of color blindness is limited. Most published studies are small, uncontrolled case series or observational reports from Chinese-language journals, which describe improvements in color discrimination after acupuncture or herbal therapy. High-quality randomized controlled trials are scarce, and there is no Cochrane review on the topic.
Some studies have shown that acupuncture at points such as Jingming BL-1 and Ganshu BL-18 may improve color vision test scores in individuals with acquired color vision deficiency, but the mechanisms remain unclear and the results are inconsistent. Overall, while TCM offers a plausible theoretical framework, robust clinical evidence is lacking, and treatment should be considered complementary rather than curative.

Frequently asked questions
Common questions about using Traditional Chinese Medicine for color blindness.
For congenital color blindness, acupuncture and herbs are unlikely to produce a dramatic cure, but they can strengthen the underlying constitution and may improve overall visual comfort, contrast sensitivity, and eye fatigue. For acquired color vision loss, especially when it is linked to a clear pattern like Liver Fire or Blood Stagnation, many patients report noticeable improvement. Acupuncture works by stimulating points around the eyes and along the Liver and Kidney channels to increase local circulation and regulate the flow of Qi.
This varies by pattern. If your color vision change is recent and due to an excess condition like Liver Fire, you might notice changes in a few weeks. For long-standing deficiency or congenital patterns, expect to commit to at least 3-6 months of weekly acupuncture and daily herbs before evaluating progress. The first sign of improvement is often not a dramatic return of color, but rather less eye strain, better night vision, or a feeling of brighter, clearer sight.
Yes, absolutely. TCM treatment does not interfere with corrective lenses. In fact, many people find that acupuncture and herbs reduce eye fatigue and dryness, making wearing lenses more comfortable. There is no known interaction between TCM and standard eyewear.
TCM can be safely used in children, often with dietary therapy, gentle herbal formulas, and pediatric acupuncture (or acupressure for very young children). For congenital color blindness, the goal is to support the development of the visual system by nourishing Liver Blood and Kidney Essence. While it may not normalize color vision on a test, many parents report that their child seems more visually engaged and less prone to eye rubbing or squinting. Always work with a practitioner experienced in pediatric care.
Generally, you want to favor foods that nourish Liver Blood and Kidney Essence: dark leafy greens, goji berries, black sesame seeds, bone broth, eggs, and small amounts of high-quality animal liver. Avoid excessive spicy, greasy, or deep-fried foods, which can generate Dampness and Heat that cloud the eyes. For specific pattern-based dietary advice, your TCM practitioner will provide a tailored plan.
No. Herbal formulas are typically prescribed in cycles, with breaks to allow the body to adjust. For chronic or congenital conditions, a practitioner might recommend a maintenance dose of a gentle formula like Qi Ju Di Huang Wan for longer periods, but this is not the same as taking a strong prescription indefinitely. The goal is always to restore balance so that the body can sustain itself.
