眼睛的视觉功能依赖于肾精。血液滋养功能归属于肝。瞳孔中的一点神光，本质上是水（肾精）的表现，外面包裹着一层薄膜，晶莹剔透，目光深远透彻，这是人赖以生存的根本。当它发生病变时，如果肾水虚弱，就会出现视物昏花；如果肝火旺盛，就会出现眼睛发红、干涩。如果遇到风寒，就会引发疼痛、眼屎增多和流泪。只要肝肾充实，即使遭受外邪侵袭，也不会造成危害；反之，如果肝肾亏虚，即使没有外邪，也会自行产生灾祸。
如今看到世人常常患上眼疾，只热衷于点药和清洗，甘心受害，反而认为通过内在调养和内部治疗是迂腐缓慢且无效的。这实在令人哀悯。所谓的点眼药，通常以炉甘石为主药。一旦经过煅炼，其性质变得燥烈，就会妨碍睡眠并耗损精气。麝香片，质地辛香，性质善于走窜经络，冲开道路，反而会引风邪进入眼窍。琥珀、珍珠、石燕、铜青，都是金石类剽悍酸烈的药物，会进一步枯竭津液。熊胆、黄连，性质苦寒而凝滞壅塞，使风邪不能发散透达。
那些正值壮年、元气健实的人，患此病只需清静调养，等待经气耗尽、正气恢复，不治也能自愈。即使使用点洗疗法，也不是药物的功效。即使是衰老瘦弱的人，如果不治疗，也只是病气滞留，并没有大害。但如果敷上前面提到的那些燥烈药物，就会削薄那层保护性的薄膜；使用走窜的药物，就会散失真气；导致瞳神精气外脱，逼迫眼泪流出，泪干后视力忽明忽暗，直到失明才停止，这难道是眼睛自己瞎的吗？我认为所有眼病都应当在脾、肝、肾三脏处寻找根源进行治疗，没有不痊愈的。
苏东坡说：患眼病就要让它休息，患牙病就要让它劳作。治疗眼睛就像治理百姓，应当像曹参治理齐国那样（无为而治）；治疗牙齿就像治理军队，应当像商鞅治理秦国那样（严刑峻法）。这话真是有深意啊，怎能不仔细思考呢？因此列举我经验中的案例作为借鉴。
甲申年秋天，姜子社的祖母年近七十岁，患了风邪，双眼红肿疼痛。请了一位眼科医生，使用点药法。过了几天，左眼竟然失明了。又给她服用清火耗气的药剂，反而增加了头晕目眩、自汗的症状，右眼也变昏花，病情加重。请我去诊治，我投以补中益气汤，加入熟地黄、五味子、枸杞子、决明子等药，服用数剂后，汗止住了，右眼恢复了光明。
另外，子社张家姻母也患有同样的病症。她当时刚五十岁，元气还算充实。我让她在密室避风，遇到疼痛千万不要揉按，有眼泪就任其自流，放宽心情恬淡休养，兼吃清淡饮食，只需忍耐七天，然后投以清肝滋肾的药物，服用数剂。她能遵守禁忌，到期后眼睛恢复如初。
还有，我的洪门表姐在甲申年夏天患眼生翳膜。请刘润初治疗。刘医生说必须内外兼治才能痊愈。于是刘润初专门治疗外部症状，我则用健脾养血的药剂，滋补脾、肝、肾三经。十天后翳膜消退，身体比之前更健康。
戊寅年春天，我因为要去东胶办事，到了夏天，先妻患有脾泄（腹泻）久治不愈。一位医生使用辛温燥热的药剂，服用了数十天，腹泻虽然好了，但哪知道前面的药物耗干了血液，导致一只眼睛失明，另一只眼睛也几乎毁坏。我回家后急忙投以滋阴益肾的药剂，服用三十副后才恢复光明。至于左眼的肾精不能上行注于目系，如果断绝了就无法治疗了。
侄子允敷经常患红眼病，六脉沉迟。我让他服用八味丸，以及恣意饮用鸡汤和酒，随即痊愈。原来红眼病也有寒证，怎么能一概投用凉性药剂呢？详细陈述这几个病例来告诫患者。
The visual function of the eyes relies on Kidney Jing (Kidney Essence). The nourishing function of blood is attributed to the Liver. The point of divine light in the pupil is essentially Water (representing Kidney Essence), wrapped externally by a thin membrane, crystal clear, with vision extending far and deep; this is the foundation upon which life depends. When pathology occurs: if Kidney Water is deficient, there will be blurred vision; if Liver Fire is excessive, there will be redness and dryness/astringency. Upon encountering Wind-Cold, pain, increased eye discharge (mucus), and tearing will occur. As long as the Liver and Kidneys are solid, even if attacked by external pathogens, no harm will result. Conversely, if the Liver and Kidneys are deficient, disaster will arise spontaneously even without external pathogens.
Nowadays, it is seen that people often suffer from eye diseases, only diligently applying drops and washing, willingly suffering harm, while regarding internal nourishment and internal treatment as pedantic, slow, and ineffective. This is truly pitiable. The so-called eye drops primarily use Calamina (Lugan Shi) as the sovereign herb. Once calcined, its nature becomes drying and hot, thereby hindering sleep and exhausting Jing (Essence). Musk Pian (She Xiang Pian), with its pungent and aromatic quality, has a nature good at penetrating meridians and clearing pathways, which instead attracts Wind pathogens into the orifices. Amber (Hu Po), Pearl (Zhen Zhu), Swallow Stone (Shi Yan), and Verdigris (Tong Qing) are all metallic and mineral substances that are fierce, sour, and harsh, further depleting body fluids. Bear Gallbladder (Xiong Dan) and Coptis Rhizome (Huang Lian) have bitter-cold properties that cause stagnation and obstruction, preventing Wind pathogens from being dispersed and vented.
Those in their prime with robust Yuan Qi (Primal Qi) who suffer from this condition need only maintain tranquility and adjust their lifestyle; waiting for the pathogenic factor to exhaust itself and Qi to recover, they will heal without treatment. Even if treated with drops and washes, it is not due to the efficacy of the medicine. Even for the elderly and emaciated, if left untreated, the pathogenic Qi merely lingers, causing no major harm. However, if applied with the aforementioned drying and harsh medicines, the protective thin membrane is eroded; the penetrating substances scatter the True Qi; the essence of the pupil escapes outward, forcing tears to flow. When tears dry up, vision flickers between clarity and darkness until blindness ensues. Is this truly the eye going blind on its own? I believe that all eye diseases should seek their source in the Spleen, Liver, and Kidneys for treatment, and none will fail to recover.
Su Dongpo said: "When treating eye diseases, let them rest; when treating tooth diseases, exert them." Treating eyes is like governing the people; one should govern like Cao Can governed Qi (through non-action). Treating teeth is like managing soldiers; one should manage like Shang Yang governed Qin (with strict laws). These words are profound. How can one not ponder them carefully? Therefore, I cite these experienced cases as a mirror for reflection.
In the autumn of Jiashen year, Grandmother of Jiang Zishe, nearly seventy years old, suffered from Wind Pathogen, with both eyes red and painful. An ophthalmologist was consulted, using the drop method. After several days, her left eye became completely blind. She was then administered formulas that cleared fire and consumed Qi, which exacerbated dizziness, vertigo, and spontaneous sweating, and her right eye also became dim. The condition worsened. I was invited to treat her and prescribed Buzhong Yiqi Tang (Tonify the Middle and Augment the Qi Decoction), added with Shu Di Huang (Prepared Rehmannia Root), Wu Wei Zi (Schisandra Fruit), Gou Qi Zi (Goji Berry), and Jue Ming Zi (Cassia Seed). After several doses, the sweating stopped, and her right eye regained sight.
Furthermore, the mother-in-law of the Zhang family (related to Zishe) suffered from the same condition. She was just fifty years old, and her Yuan Qi was still substantial. I instructed her to avoid wind in a closed room, strictly avoiding rubbing or pressing when pain occurred, allowing tears to flow naturally, maintaining a relaxed and tranquil mind, eating a bland diet, and simply enduring for seven days. Then, I administered herbs to clear the Liver and nourish the Kidneys. After several doses, because she observed the restrictions, her vision recovered completely by the end of the period.
Additionally, my cousin from the Hong clan suffered from eye pannus (corneal opacity) in the summer of Jiashen. Liu Runchu was invited to treat her. Liu stated that internal and external treatment combined would lead to recovery. Thus, Liu Runchu focused solely on external treatment, while I used formulas to invigorate the Spleen and nourish Blood, tonifying the Spleen, Liver, and Kidney meridians. Within ten days, the pannus disappeared, and her physical condition improved beyond before.
In the spring of Wuyin year, due to a trip to Dongjiao, by summer, my late wife suffered from chronic Spleen diarrhea (Pi Xie) that did not heal. A physician used acrid-drying agents. After taking them for dozens of days, the diarrhea ceased. Little did he know that the previous drugs had dried up the Blood, resulting in the blindness of one eye, and the other eye was nearly ruined. Upon my return, I urgently administered Yin-nourishing and Kidney-benefiting agents. After thirty doses, she finally regained sight. Regarding the left eye, if the Kidney Jing cannot ascend to nourish the optic nerve connection, once severed, it cannot be treated.
My nephew Yunfu frequently suffered from red eye disease. His six pulses were deep and slow. I instructed him to take Bawei Wan (Eight-Ingredient Pill) and to freely drink chicken soup and wine, after which he recovered. It turns out that red eye disease can also be caused by Cold. How can one generally administer cooling agents? I detail these few cases to warn patients.
