Dry Eye and Chinese Medicine: Yin and Tear Film

By Makari Wellness, updated September 5, 2026

Burning, Gritty, and Paradoxically Watery

Dry eye is one of the most common complaints in ophthalmology and one of the most misunderstood. The name suggests simple dryness — but the presentation is often counterintuitive: burning, grittiness, a foreign-body sensation, light sensitivity, and, paradoxically, excessive tearing. That reflexive tearing is the eye's emergency response to chronic surface dryness — the lacrimal glands flooding the eye with thin, unstable tears that evaporate almost immediately, leaving the surface no better off than before.

Conventional medicine recognizes two main types: aqueous-deficient dry eye, where the lacrimal glands simply produce insufficient tear volume, and evaporative dry eye, the more common form, where meibomian gland dysfunction (MGD) leads to a deficient lipid layer that allows tears to evaporate too quickly. The distinction matters clinically — and it maps, with some precision, onto the Chinese medicine pattern framework. Here is how classical medicine reads what is happening in the tear film and what it offers as a supportive layer of care.

When Conventional Care Has Limits

Prescription eye drops, artificial tears, punctal plugs, warm compresses, and meibomian gland expression are all useful tools. Cyclosporine and lifitegrast address the inflammatory component of dry eye. Intense pulsed light (IPL) therapy for MGD has shown meaningful results in clinical trials.

And yet: millions of people cycle through these treatments with incomplete or temporary relief. Dry eye is a systemic condition for many patients — connected to sleep, stress, hormonal shifts, diet, screen exposure, and constitutional terrain that topical treatments address only at the surface. Classical Chinese medicine, which has always understood dry eye as a whole-body fluid metabolism disorder rather than a local eye-surface problem, offers a different entry point into the same clinical picture.

Three TCM Patterns in Dry Eye Disease

Chinese medicine identifies dry eye through three primary pattern categories, often layered in the same patient:

Liver Yin Deficiency (Gān Yīn Xū, 肝阴虚)

This is the foundational pattern for dry eye in classical medicine. The Liver "opens to the eyes" — Gān Kāi Qiào Yú Mù (肝開竅於目) — meaning that Liver Qi and Liver Yin directly nourish the visual apparatus. When Liver Yin is insufficient — from age, overwork, chronic stress, insufficient sleep, or constitutional depletion — the fluid substrate that moistens the eyes is inadequate at its source. This pattern presents with dry, tired, and burning eyes that worsen in the evening; visual blurring with prolonged use; and a broader clinical picture of Yin depletion: night sweats, warm hands and feet, difficulty sleeping, and a constitution that runs thin rather than robust. It corresponds most closely to aqueous-deficient dry eye — the fluid generation side of the equation.

Lung-Spleen Qi Deficiency (Fèi Pí Qì Xū, 肺脾气虚)

The Lung governs the skin and the body's fluid secretion onto surfaces — including the conjunctiva and the ocular surface. When Lung Qi is deficient, the body's capacity to secrete and distribute fluids at the surface layer is impaired. The Spleen, which governs the transformation and upward distribution of fluids absorbed from food, is the pump that delivers fluid to where the Lung disperses it. When either is deficient, the delivery system fails even when the Yin substrate exists. This pattern corresponds most closely to meibomian gland dysfunction and evaporative dry eye — not a shortage of Yin, but a failure of distribution and secretion. Clinically, these patients often show general fatigue, digestive weakness, and a pale complexion alongside their eye symptoms.

Yin Deficiency with Empty Heat (Yīn Xū Huǒ Wàng, 阴虚火旺)

When Yin deficiency is prolonged, the cooling, moistening counterbalance to Yang is insufficient. Yang — no longer anchored by adequate Yin — generates a smoldering "empty Heat" that rises and inflames without the acute quality of true Fire. In the eyes, this presents as a burning, redness, and heat sensation that is chronic and low-grade rather than acute and intense. It is the inflammatory component of dry eye expressed through the deficiency lens: the heat of a body running dry rather than inflammation from excess pathogen invasion. The typical picture is a feeling of something irritating in the eye, sensitivity to light, and an unrelenting sensation of heat that worsens as the day progresses.

The Five Regions Lens: Sclera and Eyelids

Two of the contemporary Five Regions organ mappings are particularly relevant to dry eye:

• Sclera, Lung (Qi Wheel, 氣輪) — the white of the eye, including the conjunctival surface, is the Lung's domain; the Lung governs fluid secretion onto surfaces; when Lung Qi is deficient, the conjunctival and corneal surfaces lose their fluid distribution
• Eyelids, Spleen (Flesh Wheel, 肉輪) — the eyelids are governed by the Spleen; the meibomian glands, embedded in the eyelid margins, depend on Spleen function for their secretory capacity in classical terms; MGD is often a Spleen Qi deficiency picture

This mapping explains why the M48 protocol for dry eye targets Lung and Spleen pathways alongside the Liver — the organ-anatomy correspondence tells us which channel systems are involved in the tear film and the ocular surface.

Acupuncture for Dry Eye: M48 and the Drying Protocol

M48 (Micro Acupuncture 48), the protocol Makari uses for degenerative eye disease, classifies dry eye in the "Drying" category — conditions characterized by Liver and Kidney Yin deficiency leading to fluid insufficiency. M48 is built on the ECIWO holographic mapping: the idea that organ systems can be influenced through precisely located distal points on the hands and feet. Michael is M48 (Micro Acupuncture 48) certified by Dr. Andy Rosenfarb. For dry eye, the protocol addresses both the Yin substrate failure and the Lung-Spleen delivery failure:

• LR-A (Liver sensory/distal) — the primary Liver point in the M48 system; Liver Yin deficiency drives the foundational dry-eye picture; LR-A addresses the functional sensory dimension of Liver deficiency
• LU-A (Lung sensory/distal) — Lung governs fluid secretion and the skin/surface layer; LU-A addresses the secretory failure component; particularly relevant for the MGD / evaporative picture where the Lung-Spleen delivery failure is primary
• SP-B (Spleen structural/proximal) — B points address the constitutional, chronic, deficiency dimension; SP-B is indicated when Spleen Qi root deficiency underlies the fluid distribution failure; strengthens the delivery layer from its constitutional base

Needles are 34-gauge, half-inch, inserted at approximately 45° angle onto the periosteum, 30-minute retention. We agree a block of visits up front and re-check before continuing. We cannot promise a response, and we say that plainly at the start of every course of care. Long-standing Yin and Qi depletion usually calls for a longer course of care than a more acute presentation.

Scalp Acupuncture and Periorbital Adjuncts

The Scalp Vision Area is less central to dry eye than to conditions with more prominent optic nerve or retinal involvement. For dry eye patients, we more commonly employ periorbital adjunct points to support local fluid secretion and the ocular surface:

• BL-2 (Zanzhu) — at the medial end of the eyebrow; classic local point for eye problems; used for the lacrimal drainage area and periorbital circulation
• SJ-23 (Sizhukong) — at the lateral end of the eyebrow; the Triple Jiao channel governs fluid metabolism; SJ-23 supports periorbital Qi and fluid distribution

When electro-stimulation is applied to these periorbital points, we use 1–4 Hz — the chronic-degeneration range appropriate for Yin-deficiency and Qi-deficiency presentations — with the aim of gently supporting local fluid secretion and periorbital microcirculation without over-stimulating a constitution that is already depleted.

Chinese Herbal Support for Dry Eye

The herbal approach to dry eye targets the Yin deficiency root and the fluid-delivery failure simultaneously. Classical choices include:

• Mai Men Dong (Mài Mén Dōng, 麦门冬) — ophiopogon tuber; the primary Yin-nourishing and fluid-generating herb; nourishes Lung-Stomach Yin and promotes fluid secretion; addresses both the Lung delivery failure and the Yin substrate deficiency
• Sha Shen (Shā Shēn, 沙参) — glehnia root; fluid-generating and Lung-moistening; a gentle but sustained Yin tonic with specific affinity for the secretory surfaces; used alongside Mai Men Dong for the Lung-Yin and surface-moisture picture
• Ju Hua (Jú Huā, 菊花) — chrysanthemum; the classical eye herb; cools Liver Heat, brightens the eyes, and addresses the empty-Heat burning component of Yin deficiency dry eye
• Gou Qi Zi (Gǒu Qǐ Zǐ, 枸杞子) — wolfberry; nourishes Liver and Kidney Yin and Blood; a classical tonic specifically for the eye-moistening and visual-brightening functions of Liver-Kidney Yin
• Bai He (Bǎi Hé, 百合) — lily bulb; nourishes Lung Yin and moistens dryness; addresses the surface-secretion failure of the Lung Qi deficiency picture; a gentle, food-grade herb that supports the fluid-distribution layer without heavy tonification

Formula design integrates these according to which pattern layer is most prominent. A Liver-Yin-deficiency-primary formula looks different from a Lung-Spleen-Qi-deficiency formula, though both address "dry eye" in the Western sense. The pattern determines the formula.

Nutrition and Functional Medicine, Through the Pattern

Functional medicine research on dry eye converges on two areas, which we read through the same pattern diagnosis. At the level of food and physiology:

• Omega-3 fatty acids: EPA and DHA, found in oily fish, take part in meibomian gland secretion and the lipid layer of the tear film, and omega-3 intake has been studied in clinical trials for evaporative dry eye. This sits naturally beside the Lung-Spleen delivery pattern in classical medicine — the lipid secretion function that classical medicine addresses through the Lung-governing-surfaces channel.
• Antioxidants: Chronic ocular surface inflammation is driven in part by oxidative stress. Vitamins C and E, lutein and zeaxanthin, and astaxanthin have been examined for antioxidant activity at the ocular surface. These sit beside the Yin-deficiency empty-Heat pattern — the body's cooling capacity when the constitutional Yin substrate is depleted.

Nutrition follows the classical pattern diagnosis rather than a separate supplement stack. What fits the Liver-Yin or Lung-Spleen picture is chosen together with the herbal formula and the acupuncture protocol.

What the Research Shows

A 2026 systematic review in Frontiers in Medicine by Bautista-Hernández MA and colleagues examined clinical evidence on acupuncture for ocular conditions. Their conclusion: current evidence is insufficient for definitive claims — heterogeneous studies, small sample sizes, variable methodology. This is not a verdict against acupuncture; it is a call for more rigorous integrative research. Frontiers in Medicine, 2026.

For dry eye specifically, there are promising findings around acupuncture's effects on lacrimal gland function and ocular surface inflammation, but the evidence is preliminary. We are honest with every patient about what we know and what remains to be studied. What we can say is that reading the pattern correctly — Yin deficiency, Lung-Spleen Qi deficiency, or both — and matching the treatment to it is the core of how we work, and we review progress with you as we go.
