Night blindness, or nyctalopia, is difficulty seeing in low light or darkness. It's not a disease itself but a symptom of an underlying issue with the retina's rod cells, which are responsible for vision in dim conditions. Common causes include vitamin A deficiency, retinitis pigmentosa, cataracts, glaucoma, and certain medications.
Diagnosis typically involves a detailed eye exam, visual field testing, and sometimes electroretinography to measure retinal function. Treatment depends on the cause - vitamin A supplements for deficiency, surgery for cataracts, or low-vision aids for degenerative conditions. For many inherited retinal diseases, conventional options remain limited.
Conventional treatments
Conventional treatment targets the underlying cause. If vitamin A deficiency is identified, supplementation is the primary approach and can reverse the symptom. Cataract surgery restores clarity when the lens has clouded. For progressive conditions like retinitis pigmentosa, management focuses on low-vision aids, protective eyewear, and sometimes vitamin A palmitate to slow progression, though results vary. Genetic therapies are emerging but not yet widely available.
Where conventional treatment falls short
While correcting a vitamin deficiency or removing a cataract can resolve night blindness quickly, many people have no clear reversible cause - especially in degenerative retinal conditions. For them, conventional medicine offers symptom management but not a way to rebuild the eye's underlying vitality. It also doesn't account for the constitutional differences TCM identifies: one person's night blindness may stem from digestive weakness, another's from kidney depletion, and another's from blood stagnation. By not differentiating these roots, conventional care misses the chance to nourish the whole system that supports vision.
How TCM understands night blindness
In TCM, the ability to see in darkness depends on the eyes being richly supplied with Blood and Essence. The Liver stores Blood, and its channel opens directly into the eyes. When Liver Blood is plentiful, the eyes are moist, bright, and adapt easily to changing light. When it's deficient, the eyes become dry and struggle in dim conditions. The Kidneys store Essence, the deepest source of yin and yang in the body, and this Essence rises to nourish the pupils. If Kidney Yin or Yang is depleted, the foundational fuel for vision runs low.
The Spleen plays a quieter but equally vital role. It transforms food into Qi and Blood - the raw materials the Liver and Kidneys need. A weak Spleen means not enough Blood is made to reach the eyes, no matter how well the other organs are functioning. That's why digestive symptoms like bloating and fatigue often accompany night blindness in Spleen-deficient patterns.
Because night vision relies on this chain of supply - Spleen makes Blood, Liver stores it, Kidneys provide Essence - a breakdown at any point can cause the same symptom. That's why one person's night blindness might come with dry eyes and pale nails (Liver Blood Deficiency), while another's comes with low back pain and feeling cold (Kidney Yang Deficiency). TCM treatment traces the symptom back to its origin and rebuilds from there.
「雀目者，昼而精明，至暝则不见物，世谓之雀目，言如鸟雀，暝便无所见也。」
"Night blindness means clear vision during the day but inability to see at dusk; it is called 'bird's eye' because, like a sparrow, one sees nothing at nightfall."
How a TCM practitioner diagnoses night blindness
Inside the consultation
To understand why night vision is failing, a TCM practitioner looks at the whole person, not just the eyes. The first clues come from the quality of the vision loss and the accompanying body signs. Is the eye dry and gritty, or does it ache? Is the person tired and pale, or restless and warm? These details point toward different underlying patterns of disharmony.
When the main complaint is dry, tired eyes with blurred vision and perhaps pale nails, the practitioner suspects Liver Blood Deficiency. The Liver stores Blood and its channel opens to the eyes; without enough nourishing Blood, the eyes become malnourished. The tongue is often pale and the pulse thin, confirming that Blood is not reaching the sense organs.
If poor night vision comes with poor appetite, bloating, loose stools, and a sallow complexion, the root is likely Spleen Qi Deficiency. The Spleen transforms food into Qi and Blood; when it is weak, not enough Blood is produced to feed the eyes. A pale tongue with a thin coat and a weak pulse support this diagnosis.
In older adults or those with long-term strain, night blindness may be accompanied by dry eyes, floaters, tinnitus, dizziness, and soreness of the lower back and knees. This points to Kidney and Liver Yin Deficiency. The tongue is red with little coating, and the pulse is thin and rapid, indicating a deep depletion of the body’s cooling, moistening fluids.
When night blindness appears alongside marked fatigue, pale face and lips, dizziness, and heart palpitations, the pattern is likely a broader Qi and Blood Deficiency. Here both the energy and the material Blood are insufficient to raise clear Yang to the head and eyes. The tongue is pale and may be slightly swollen, and the pulse is thin and weak.
If the person feels constantly cold, has a low and aching back, and lacks vitality, the deeper issue may be Kidney Yang Deficiency. The warming Ming Men Fire is failing to transform essence into the bright, nourishing fluids the eyes need. The tongue is pale and puffy with a white coat, and the pulse is deep and weak.
When night blindness comes with a dull, fixed aching around the eyes, and the complexion is dark or the tongue shows purple spots, the practitioner considers Blood Stagnation. Often this develops after long-standing deficiency; the blood flow becomes sluggish and fails to irrigate the eye collaterals. The pulse feels choppy or wiry.
TCM Patterns for Night Blindness
In TCM, the aim is to address the root cause, not just the symptom — it calls that root cause a “pattern.” The same night 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 common to recognize yourself in more than one of these patterns. Many of them share a foundation of deficiency, and they often overlap. For example, long-term Spleen Qi Deficiency can lead to Qi and Blood Deficiency, and eventually to Liver Blood Deficiency. So you may see a mix of digestive weakness, fatigue, and dry eyes all at once.
To get a clearer picture, notice which cluster of symptoms is strongest and which appeared first. If poor appetite and bloating dominate, the Spleen is likely the root. If cold limbs and low back pain are the most bothersome, consider Kidney Yang. The tongue and pulse, however, can reveal the deepest layer, which is why self-assessment alone can be tricky.
Because night blindness can sometimes signal a serious underlying condition like retinitis pigmentosa or vitamin A deficiency, it is wise to see a professional for a full diagnosis. A TCM practitioner can read the tongue and pulse to pinpoint the pattern and tailor treatment. If your night vision worsens suddenly or is accompanied by eye pain, seek care promptly.

Formulas traditionally used for night 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 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 that simultaneously replenishes both Qi and Blood, created by combining two famous prescriptions: Si Jun Zi Tang (for Qi) and Si Wu Tang (for Blood). It is commonly used for people who feel chronically tired, look pale or sallow, have a poor appetite, experience dizziness or heart palpitations, and feel generally run down due to dual deficiency of Qi and Blood.
A classical warming and tonifying formula designed to restore Kidney Yang, the body's foundational warmth and vitality. It is commonly used for people experiencing deep fatigue, persistent cold sensations, lower back weakness, reduced sexual function, or frequent urination due to depletion of the Kidney's warming capacity. The formula combines Yang-warming herbs with nourishing substances to rebuild vitality from within, following the principle that Yang is best restored by providing it with a nourishing Yin foundation.
A classical formula designed to improve blood circulation in the chest, relieve pain, and ease emotional tension. It is widely used for chronic chest pain, stubborn headaches, insomnia, and irritability caused by poor blood flow and stagnation in the upper body.
Most people see gradual improvement in night vision within 4 to 12 weeks of consistent acupuncture and herbs. Deficiency patterns like Liver Blood or Kidney Yin may require 3 to 6 months to rebuild deep reserves, while Blood Stagnation sometimes responds faster once circulation is restored. Acupuncture is typically once or twice weekly, with daily herbs, and progress is often felt as less eye strain and clearer vision in low light before full dark adaptation returns.
Treatment principles
Across all patterns, the goal is to restore the flow of nourishment to the eyes. For deficiency patterns - whether of blood, qi, yin, or yang - treatment builds up what is lacking, using herbs, acupuncture, and food to fill the reserves. For blood stagnation, the aim is to move the blockage so fresh blood can reach the retina.
Many people have mixed patterns, so formulas are often tailored to address both the root deficiency and any secondary stagnation or dampness.
Treatment is never just about the eyes. By strengthening the spleen, nourishing the liver, and supporting the kidneys, the whole body becomes more resilient - and vision often improves as a natural result.
What to expect from treatment
Acupuncture sessions are typically scheduled once or twice a week for the first 6 to 8 weeks, then spaced out as vision stabilizes. Herbal formulas are taken daily, usually in easy-to-use granule or pill form. Most people notice less eye dryness and strain within the first month.
True improvement in night adaptation is gradual - like watching a dimmer switch slowly turn up - and continues over several months. Lifestyle and dietary changes are essential partners; without them, the effects of treatment may be slower to take hold.
General dietary guidance
Favour warm, cooked foods that are easy to digest and rich in blood-building nutrients: dark leafy greens, beets, black beans, eggs, goji berries, and small amounts of organ meats like liver if suitable. Bone broths and congees are especially gentle on the spleen.
Limit cold, raw foods, excessive dairy, and greasy or spicy dishes that can create dampness and impair digestion. A cup of goji berry and chrysanthemum tea in the evening is a classic TCM tonic for the eyes.
Combining TCM with conventional treatment
TCM can safely complement most conventional treatments for night blindness. If you're taking prescription medications or high-dose supplements, share the full list with your TCM practitioner. Some blood-nourishing herbs can influence clotting; if you take blood thinners, your practitioner may adjust the formula. Always keep your eye doctor informed about any complementary therapies you're using, and never stop prescribed treatments without medical guidance.

Safety & special considerations
-
Sudden loss of night vision — Especially if it occurs in one eye or appears over hours to days, this may indicate a retinal detachment or vascular event.
-
Night blindness with eye pain or redness — These could signal acute glaucoma or inflammation requiring immediate treatment to prevent permanent damage.
-
Seeing flashes of light or a sudden shower of new floaters — This can be a warning sign of retinal tear or detachment, which needs urgent ophthalmologic evaluation.
-
Night blindness with severe headache, nausea, or vomiting — This combination may point to acute angle-closure glaucoma or a neurological condition.
-
Night blindness in a child with poor growth or frequent infections — Severe vitamin A deficiency can threaten vision and overall health; prompt medical assessment is critical.
Audience-specific guidance — open what applies to you
Pregnancy naturally draws heavily on the mother’s Blood and Essence, so pre-existing Liver Blood Deficiency or Kidney Yin Deficiency often deepens, making night blindness more noticeable. Nourishing formulas like Qi Ju Di Huang Wan and Shen Ling Bai Zhu San are generally considered safe, but any formula containing blood-moving or strongly warming herbs must be avoided - Xue Fu Zhu Yu Tang (with Tao Ren and Hong Hua) and You Gui Wan (with Fu Zi) are contraindicated during pregnancy.
Acupuncture is an excellent alternative, but certain points must be omitted: Hegu LI-4 and Sanyinjiao SP-6 are traditionally avoided in pregnancy, as is strong stimulation on the lower back and abdomen. Gentle needling at Jingming BL-1, Ganshu BL-18, and Zusanli ST-36 can safely support eye nourishment without risk.
Lactation further depletes Blood and Qi, so night blindness may persist or emerge postpartum. The same deficiency patterns - Liver Blood Deficiency, Qi and Blood Deficiency, and Spleen Qi Deficiency - are common. Herbal treatment can continue, but formulas containing Fu Zi (as in You Gui Wan) or strong blood movers like Tao Ren and Hong Hua should be avoided because their properties can pass into breast milk and affect the infant.
Qi Ju Di Huang Wan, Ba Zhen Tang, and Shen Ling Bai Zhu San are gentle and compatible with breastfeeding. Acupuncture is very safe during lactation and can be used freely, with the same point selections as for non-lactating adults, provided the mother is comfortable and well-hydrated.
In children, night blindness is most often a sign of Spleen Qi Deficiency or Liver Blood Deficiency stemming from malnutrition, picky eating, or prolonged illness. The child may not complain of poor night vision; instead, parents notice stumbling in dim rooms or fear of the dark. The tongue is often pale and puffy with a thin coat, and the child may be thin, sallow, and prone to digestive upset.
Treatment centres on dietary therapy first - small, warm, easily digested meals with Blood-nourishing foods like liver, egg yolk, and goji berries. Shen Ling Bai Zhu San can be given at one-quarter to one-half the adult dose, depending on age and weight. Acupuncture is rarely the first choice in very young children; instead, paediatric tuina or gentle acupressure at Zusanli ST-36 and Pishu BL-20 is used to strengthen the Spleen and raise clear Yang to the eyes.
In the elderly, night blindness is almost always a deficiency problem - Kidney and Liver Yin Deficiency or Kidney Yang Deficiency predominate. The eyes lose their spark because the deep reserves of Essence and Yang have dwindled over decades. Treatment is slower and gentler: Qi Ju Di Huang Wan to nourish Yin and brighten the eyes, or a modified You Gui Wan (often without Fu Zi) to warm the Gate of Life and lift Yang to the pupils.
Dosages should be reduced - typically two-thirds of the standard adult dose - and the practitioner must be alert to polypharmacy interactions with Western medications for hypertension, diabetes, or glaucoma. Acupuncture is well-tolerated, but needle retention times may be shorter and points like Mingmen DU-4 respond beautifully to moxibustion, which elderly patients often find deeply comforting.
Evidence & references
Evidence for TCM treatment of night blindness is still developing. Most studies focus on retinitis pigmentosa, a genetic cause of progressive night blindness. Several small randomized controlled trials have shown that acupuncture, alone or combined with herbal medicine, can improve visual field, dark adaptation, and electroretinogram parameters, though the effect sizes are modest and long-term follow-up is limited.
Herbal formulas like Qi Ju Di Huang Wan have been studied in China for age-related macular degeneration and diabetic retinopathy, conditions that often include night vision complaints. These trials report improvements in visual acuity and contrast sensitivity, but most are small, single-centre, and lack placebo controls. High-quality, multi-centre RCTs are needed before firm conclusions can be drawn.
Key clinical studies
A 2019 systematic review of 12 RCTs involving 968 patients found that acupuncture significantly improved visual field mean sensitivity and electroretinogram b-wave amplitude compared to Western medical therapy alone. The quality of evidence was graded low to moderate due to risk of bias in included studies.

In a 12-week RCT of 60 patients with dry AMD, those receiving Qi Ju Di Huang Wan plus routine care showed greater improvement in contrast sensitivity and low-luminance visual acuity compared to routine care alone (P<0.05). Night vision complaints were not a primary endpoint but improved in the herbal group.

Frequently asked questions
Common questions about using Traditional Chinese Medicine for night blindness.
Yes, many patients report clearer vision in dim light after a course of acupuncture, especially when points around the eyes and on the liver and kidney channels are used. Acupuncture works by increasing local circulation and guiding the body's resources to the eyes. While it doesn't cure structural damage, it can optimize the nourishment reaching the retina and often reduces accompanying dryness and strain.
Foods that build blood and nourish the eyes are central. Goji berries, dark leafy greens, liver (if tolerated), black sesame seeds, eggs, and bone broths are excellent. Warming, cooked meals support the spleen, which is key to producing blood. Avoid too many cold, raw foods or icy drinks, which can weaken digestion and make it harder to generate the nourishment your eyes need.
You might notice less eye fatigue and a subtle improvement in dim-light comfort within 4 to 6 weeks. Fuller restoration of night vision often takes 3 to 6 months, especially when the root is a long-standing deficiency. Consistency with herbs, acupuncture, and diet makes the biggest difference.
In most cases, yes. Many Chinese herbs that benefit night vision, like goji berries, naturally contain carotenoids. If you're taking high-dose vitamin A, it's wise to inform both your TCM practitioner and your eye doctor, as excessive vitamin A can be toxic. They can coordinate a safe, complementary approach.
While TCM cannot reverse the genetic changes in retinitis pigmentosa, many patients find that herbs and acupuncture slow the progression of vision loss and improve quality of life. Treatment focuses on nourishing kidney essence and liver blood to preserve remaining retinal function for as long as possible. It's often used alongside conventional monitoring.
Not always. Liver blood deficiency is a very common cause, but night blindness can also arise from spleen qi weakness, kidney yin or yang deficiency, or even blood stagnation. The accompanying signs - like digestive problems, coldness, or fixed eye pain - help distinguish the pattern. That's why a full TCM assessment looks at the whole person, not just the eyes.
