此章专言因害别故而累及于目也，所致不同，未能直指为甚，故统曰因他。如伤寒，酷疟热郁，蒸损瞳神，

何因而致，即以因症治之。违道不远，或第裁以本经之药，其因自得，断不可
胶柱鼓瑟，有辜病情。嗟嗟！天之赋禀已定，人之斫丧无穷，故亏者多，盈者少，泰者少而否者多。苟知爱重而
不犯戒约，居易行素，静俟天命，自然灾眚都无。万一事出意外，更以识遣识，以理止情，以不如我者巧自宽解，

亦病，病且不愈，何哉？盖禀受亏歉，纵日饱膏粱，未能应机蒸变，则当生者不生，不当克者而克。如雀目、近

现成有病居阴分，时令违和气不顺，气不顺兮阳不升，遂使清浊两相混，内外症发固因他，就事论事他勿问。
这一章专门讲述因为其他疾病或伤害而累及眼睛的情况。导致的原因各不相同，不能直接断定是最严重的病因，所以统称为“因他”（由其他原因引起）。例如：伤寒病、酷烈的疟疾热邪郁结，熏蒸损伤瞳神（瞳孔及眼内组织）；蛊胀病（腹部胀大如鼓的病证）过度服用姜、附子等温热药物而导致眼部肿胀；时疫（流行性传染病）掠夺人的元神（生命活力）；岚障（云雾状的眼部遮蔽感）干扰冒犯正气；这是一类情况；真阴（肾阴）消耗泄漏则身体萎靡，精气枯竭导致昏盲；阳气因烦劳过度而亢盛，热邪胜则产生迷惑妄动；这又是一类情况；痰症引起的厥逆眩晕，火症引起的疼痛涩滞，气症引起的结聚郁结，血症引起的红赤疼痛，这也是一类情况；总之，凡是因病而波及眼睛的，虽然外部有表象，但必须追问是什么原因为此导致的，就根据这个原因的症状来治疗。违背正道不远了，或者仅仅裁减使用本经（《黄帝内经》）的药物，病因自然得以解决，绝对不可拘泥固执，辜负了病情。唉！上天赋予的禀赋已经确定，人的自我戕害却是无穷的，所以亏损的人多，充盈的人少，顺境少而逆境多。如果知道爱惜重视而不触犯戒律约定，处于平易的环境践行朴素的本性，安静地等待天命，自然灾祸都没有。万一事情出乎意外，再用智慧遣除执念，用理智制止情感，用不如自己的人巧妙地自我宽解，心地宽容平和，与外物没有抵触，感觉鸟兽、禽鱼想要亲近人，不仅身体无病而且目光明亮，寿命也会长久。元机之士（悟性高的人），并非认为这些话是荒诞不经的，修真炼性（修养身心），应当直接奉为家法。
嗜欲少，世情疏，性气温和饮食宜。日月风霜皆不出，恹恹哑病耐人思。
这一章讲述眼睛不应该生病却生病了的情况。世间有德行高尚仁爱的人，韬光养晦涵养素朴，内在遏制人欲，外在体察天和（自然的和谐之气），应该水火既济（心肾相交，阴阳平衡），阴阳各得其所，然而眼睛也生病了，而且病久不愈，为什么呢？大概是因为禀受亏欠不足，即使每天吃丰盛的膏粱厚味，也不能顺应时机进行蒸腾变化，那么该生的不生，不该克制的反而克制。如雀目（夜盲症）、近视、残风（眼疾）、天旋（眩晕感），以及处女血气怯弱、小儿肾虚，都是造化（自然规律）使之如此。如果不是通达之人，一概用常情去衡量格拒，不仅医理不清，而且杀机早就流露在药笼中了。所以在各种有原因之外，另外增加“无因而因”（没有明显外因的病因）。三折肱者（经验丰富的医生），大概会把我的话当作指南针吧。
Currently, illness resides in the Yin aspect; when seasonal changes violate harmony and Qi is not smooth, Qi being unsmooth prevents Yang from ascending. Consequently, clear and turbid elements mix together. The emergence of internal and external symptoms is indeed due to other causes; discussing matters based on facts, one should not inquire about those "other" causes blindly.
This chapter specifically discusses how eyes are affected by harm or other diseases. The causes vary, and it is impossible to point directly to the most severe cause, so they are collectively termed "Yin Ta" (caused by others). For instance: Shanghan disease (Cold Damage), severe malaria with heat stagnation steaming and damaging the Tong Shen (pupil and intraocular tissues); Gu Zhang disease (abdominal distension like a drum) caused by excessive ingestion of Jiang (Zingiberis Rhizoma) and Fu Zi (Aconiti Lateralis Radix Praeparata) leading to eye swelling; Shi Yi (epidemic febrile diseases) snatching away Yuan Shen (vital spirit); Lan Zhang (visual obstruction like mist) interfering with Zheng Qi (healthy Qi); this is one category. Zhen Yin (True Yin/Kidney Yin) consumption and leakage lead to debility; Jing Jue (exhaustion of essence) causes dimness and blindness; Yang Qi hyperactivity due to mental fatigue leads to heat dominance causing confusion and delusion; this is another category. Jue Yun (syncope and vertigo) from Tan Zheng (phlegm disorders); Teng Se (pain and astringency) from Huo Zheng (fire disorders); Jie Yu (stagnation and depression) from Qi Zheng (Qi disorders); Chi Teng (redness and pain) from Xue Zheng (blood disorders); this is yet another category. In summary, whenever an illness affects the eyes, although there are external manifestations, one must ask what cause led to it, and treat according to that cause's symptoms. This approach is close to the Dao. One might simply select herbs from the Ben Jing (Classic of Materia Medica) to resolve the root cause. One must absolutely not be rigid and dogmatic, thereby failing the patient's condition. Alas! Heaven's endowment is fixed, but human self-destruction is endless. Thus, those who are deficient are many, while those who are abundant are few; those in prosperity are few, while those in adversity are many. If one knows to cherish oneself and avoid breaking rules, lives in simplicity and tranquility, waiting calmly for destiny, naturally disasters will be absent. If unexpected events occur, use wisdom to dispel obsession, reason to restrain emotions, and compare oneself with those less fortunate to comfort oneself. With a tolerant heart and no conflict with things, feeling that birds, beasts, fowl, and fish wish to approach, not only will the body remain healthy and vision clear, but longevity will also be achieved. Those with profound insight do not consider these words as empty talk; those cultivating truth and refining nature should take them as family precepts.
Few desires, distant worldly ties, mild temperament, suitable diet. Avoiding sun, moon, wind, and frost, one suffers from lingering, mute-like ailments that provoke deep thought.
This chapter discusses cases where the eyes fall ill without apparent cause. There are virtuous and benevolent people in the world who conceal their true nature and nurture simplicity, internally restraining human desires and externally aligning with Tian He (Heavenly Harmony). They should achieve Shui Huo Ji Ji (Water and Fire Interacting/Heart-Kidney Communication), with Yin and Yang each finding their proper place. Yet, their eyes still fall ill, and the illness persists. Why? It is likely due to deficient endowment. Even if one consumes rich foods daily, the body cannot transform them effectively at the right time. What should be generated fails to generate; what should not overcome does overcome. Examples include Que Mu (Night Blindness), Jin Shi (Myopia), Can Feng (residual wind-eye disease), Tian Xuan (vertigo sensation), as well as Chu Nu (virgins) with weak blood and Xiao Er (children) with Kidney deficiency. These are all determined by Zao Hua (Nature/Fate). Unless one is enlightened, applying common sense to judge these cases not only shows a lack of clarity in medical principles but also reveals premature lethal tendencies within the medicine cabinet. Therefore, beyond various causes, we add "Wu Yin Er Yin" (Causeless Cause). Experienced physicians (San Zhe Gong - those whose legs break three times, implying extensive experience) should regard my words as a guide.
