目疾至难治而至易治也世人目疾往往有经岁经年而不愈甚至终身为废疾者有之此岂目病
之果
难治乎亦治之不早与早治之不得其法耳盖目痛有阴阳之分而辨之不可不预也苟辨之至清用药
得
当随手即可奏功何至有废疾之成哉阳症之目痛必羞明恶亮大 必赤如火而小 反觉淡红其痛
必如刺戳流水结眵或鼻塞而不通或口渴而痰结或身发寒发热而不止此皆火拥于心腹之间肝木
气郁而成此目痛也若错认作虚症而用温补之药则必变为两眼青盲之症矣法当用开郁去风之剂
方用开目散此方之妙妙在舒肝木之气而加之去湿散火之品不去治目而目之红痛尽除大约二剂
便可收功不必多用至于阴虚之目痛虽初起之时略有微疼而痛终不甚大 不赤而小 则红如血
者
有之或小 不赤而通身作桃花色者有之无泪无眵日间少快夜则反重虽羞明而不甚腹内时时作
饥饥则痛较饱时觉重可见日而不可见灯大便溏者有之而小便反觉清长或夜发热者有之而身间
发汗不止此皆肾水虚耗不能滋润肝木肝木自顾不暇又何能上润于目必须用纯补真阴之药大剂
吞服始能水足而虚火有归经之日倘以寒凉之药治之则必胃气消亡而阳气亦因之而丧或以风药
治之散其真气而双目终无红退之时于是有昏花之症于是有拳毛倒睫之症终身成为废人而不悟
者比比也予与言及此可胜浩叹子今定一方救之实有神功名为养目至神汤此方前去补肾以生肝
使水足而肝木得养肝木有气而双目自明矣但此方必须多服为妙服至半年不特昏花者可以重明
而拳毛倒睫者亦能自愈盖治本而末治在其中正不必又治本而又去治末也

眼疾既难以治疗，又容易治疗。世人患眼疾的，往往经过一年甚至几年都不能痊愈，甚至有终身成为残疾的。这难道是眼病果然难治吗？也是因为没有及早治疗，或者及早治疗却没有掌握正确的方法罢了。大概目痛有阴证和阳证的区分，辨别它不能不预先进行。如果辨别得极其清楚，用药得当，随手就能见效，怎么会形成残疾呢？
阳证引起的目痛，一定畏光怕亮，黑睛（角膜）必定红得像火一样，而白睛（巩膜）反而显得淡红。这种疼痛一定像针刺一样，伴有流泪、分泌物结块，或者鼻塞不通，或者口渴且痰液凝结，或者身体发冷发热不止。这些都是火邪郁结在心腹之间，导致肝木之气郁滞而形成的目痛。如果错误地把它当作虚证，而使用温补的药物，就一定会变成两眼青盲（视力丧失）的病症。治疗方法应当使用开郁祛风的方剂，方子用“开目散”。这个方子的妙处，妙在舒展肝木之气，并加上祛湿散火的药物，不去直接治疗眼睛，但眼睛的红痛却自然消除，大约两剂药就可以见效，不必多用。
至于阴虚引起的目痛，虽然初起时略有轻微疼痛，但疼痛终究不是很剧烈，黑睛不红而白睛发红如血的有这种情况；或者白睛不红而全身皮肤呈现桃花色的也有这种情况。没有眼泪也没有分泌物，白天稍微舒服些，晚上反而加重，虽然畏光但不严重，腹部时时感到饥饿，饿了的时候疼痛比饱食时觉得重，可见日光而不宜见灯光。大便溏薄的有这种情况，而小便反而清长的也有这种情况；或者夜间发热的有这种情况，而身体间或出汗不止的也有这种情况。这些都是肾水虚耗，不能滋润肝木，肝木自身都顾不过来，又怎么能向上滋润眼睛呢？必须使用纯补真阴的药物，大剂量吞服，才能使得水足而虚火有归经之日。如果用寒凉药物治疗，就一定会导致胃气消亡，阳气也随之丧败；或者用风药治疗，散失真气，而双眼最终也不会消退红肿。于是出现视物昏花的症状，于是出现拳毛倒睫（睫毛向内翻转刺入眼球）的症状，终身成为残疾人而不知醒悟的人比比皆是。我谈到这些，怎能不深深叹息！现在我定下一个方子来救治，实在有神奇的功效，命名为“养目至神汤”。这个方子去掉补肾以生肝，使水足而肝木得到滋养，肝木有了生气而双目自然明亮了。但是这个方子必须多服用才好，服用到半年，不仅视物昏花的人可以重新看清，而且拳毛倒睫的人也能自愈。这是因为治本而末节的治疗也就包含在其中了，正不必又去治本又去治末。

Ocular diseases are both difficult and easy to treat. Among the general population, those suffering from eye ailments often endure them for a year or even years without recovery, and some may become permanently disabled. Is it truly that eye diseases are inherently difficult to cure? It is merely due to delayed treatment or, if treated early, the failure to employ the correct methods. Generally, eye pain is categorized into Yin and Yang syndromes, and differentiation must be performed in advance. If the differentiation is clear and the medication is appropriate, efficacy can be achieved promptly, preventing permanent disability.
Eye pain caused by Yang syndromes is characterized by photophobia (aversion to light). The cornea (Heijing) will be intensely red like fire, while the sclera (Baijing) appears relatively pale red. The pain is often described as stabbing, accompanied by tearing and crusting of discharge. It may also present with nasal congestion, thirst with phlegm accumulation, or persistent chills and fever. These symptoms arise from Fire pathogen stagnating in the heart and abdomen, leading to Qi stagnation of the Liver Wood. If this condition is mistakenly diagnosed as a deficiency syndrome and treated with warming and tonifying herbs, it may progress to Qing Mang (blindness/loss of vision) in both eyes. The treatment principle should be to resolve stagnation and dispel wind, using the formula Kai Mu San (Open Eye Powder). The efficacy of this formula lies in its ability to soothe Liver Qi and incorporate herbs that drain dampness and clear heat. By addressing the root cause rather than directly targeting the eyes, the redness and pain subside spontaneously, typically within two doses.
Conversely, eye pain resulting from Yin deficiency may initially present with mild pain that does not intensify significantly. The cornea may not be red, but the sclera may appear blood-red; alternatively, the sclera may remain non-red while the skin exhibits a peach-blossom hue. There is an absence of tears and discharge. Symptoms are milder during the day but worsen at night. Photophobia is present but mild. The patient may experience frequent hunger, with pain exacerbating when hungry compared to after meals. They may tolerate daylight but find artificial light intolerable. Stools may be loose, while urine is clear and copious. Night fevers or spontaneous sweating may occur. These manifestations indicate depletion of Kidney Water, which fails to nourish Liver Wood. When Liver Wood is unable to sustain itself, it cannot ascend to moisten the eyes. Treatment requires potent Yin-tonifying herbs administered in large doses to restore fluid balance and guide deficient Fire back to its meridian. Using cold-natured herbs may destroy Stomach Qi and deplete Yang Qi. Using wind-dispelling herbs may scatter True Qi, leaving the eyes perpetually red. This leads to blurred vision (Hun Hua) and trichiasis/inverted eyelashes (Quan Mao Dao Jie), rendering patients permanently disabled without realizing the error. Such cases are common, prompting deep sighs. Therefore, I have formulated a prescription to save these patients, named Yang Mu Zhi Shen Tang (Nourish Eyes Supreme Spirit Decoction). This formula nourishes the Kidneys to generate Liver Wood, ensuring sufficient fluids to nourish the Liver. Once Liver Qi is restored, vision clears naturally. Long-term administration (up to six months) is recommended; not only will blurred vision improve, but trichiasis may also resolve spontaneously. This exemplifies treating the root, thereby resolving the branch, eliminating the need for separate branch treatments.
