黑夜无风雨，电光何自得，骄阳越命门，神珠显灵魄。摊书章句分，隔座人面识，莫快目重离，青盲犯在即。
此目于夜间无灯无月，若电光闪焰，倏然见物。交睫则一片白光横于眼外，通宵不辄。甚而白光中恍惚能见
指动，先辈谓之神光自现。盖人禀赋素弱，好动而有内癖，极劳饱欲，精血大损，一缕不绝真阳，未能摄养阴水，
反随邪上走，故得是病。急宜大补元煎送加减八味丸或驻景丸。烦躁不宁，暂投养心丹一二服，使无根之火降而
归经，自然神光
内蕴，英华不致飞越，庶免青盲、风变之祸。
乖气氤氲上眼中，举头见月晕如虹，莫言月色天家事，灯火因何晕亦同。
此目别无甚病，但见灯视月及隙漏之处，则有碗大一圈环影睛外。其色内青红而外紫绿，绝似日华月晕，故
曰目晕。大意水衰不能制火，水火相射，则乖戾之气激而上浮，故能无中生有。譬诸日与雨交，倏然成虹，其象
亦红绿相间。朱晦翁谓虹为天地淫气，又日虹见则雨止。非水衰火盛，阴阳乖戾之征乎？凡人劳极久视，废眠强
起，便有此弊。可暂而不可常，须四君合补水宁神汤立愈，或平气和衷汤进一二剂亦妙。若以恙小而忽之，并不
加培养，丧明之前驱也。语曰∶毫末不札，将寻斧柯。慎之哉。
立方如临戎。古人品汇少而铢两多，是为劲兵，为正兵，飞龙翔鸟，直逼中军。今人铢两减，而品汇渐增，
是为疑兵，为奇兵，声东击西，多多益善。然士非精锐，握奇不逢，风后猝遇虎豹之敌，奇正皆难策应，欲乘骄

【目晕八】
在漆黑的夜晚，既无风雨，也没有月光，眼睛为何能自行看到光亮？这是因为体内的阳气越过了命门（肾间动气，生命之根），使得神珠（眼球/瞳仁）显露出灵动的魂魄。读书时文字章节分明，隔着座位的人脸也能看清，但千万不要因为视力暂时清晰而高兴，青盲病（视神经萎缩等导致的失明症）的危机就在眼前。
这种眼病表现为：在夜间没有灯光和月亮的情况下，眼前像闪电一样闪烁发光，突然就能看见物体。一闭上眼睛，就有一片白光横亘在眼前，整夜不停歇。甚至在那白光中恍惚能看到手指晃动，前辈医家称之为“神光自现”。这大概是因为人的先天禀赋素来虚弱，喜好活动且内心有不良嗜好（如纵欲），极度劳累、饱食后行房事，导致精血严重亏损。体内仅存的一缕不绝的真阳之气，未能涵养阴水，反而随着邪气向上走窜，因此得了这种病。应当紧急使用大补元煎送服加减八味丸或驻景丸。如果伴有烦躁不安，可暂时服用一两剂养心丹，使无根之火下降并回归本经，自然神光内蕴，精华不致飞散外越，从而避免青盲和风邪变证的祸患。
乖戾之气氤氲上升侵入眼中，抬头看月亮时，觉得月亮周围像彩虹一样有光环，不要说月色是天象家事，为什么灯火周围也会出现同样的光晕呢？
这种眼病本身没有什么严重的器质性病变，只是在看灯、看月亮以及透过缝隙漏光的地方时，眼前会出现碗口大小的一圈环状光影。其颜色内部呈青红色，外部呈紫绿色，极像日光或月光的晕彩，所以称为“目晕”。大致原因是肾水衰弱不能制约心火，水火相互冲射，导致乖戾之气激荡而上浮，所以能无中生有。这就好比太阳与雨水相交，突然形成彩虹，景象也是红绿相间。朱熹认为虹是天地间淫乱之气所致，又说虹出现则雨停止。这不是水衰火盛、阴阳乖戾的征兆吗？凡是人极度疲劳、久视伤血、废寝忘食强行起床，就会出现这种弊端。这种情况可以暂时出现，但不能经常发生，必须用四君子汤合补水宁神汤治疗，立竿见影；或者服用平气和衷汤一二剂也很奇妙。如果因为病症轻微而忽视它，并不加以调养培养，这是失明的前兆。俗话说：“毫末不扎，将寻斧柯”（小病不及时治，大病就会找上门）。一定要谨慎啊。
开立方子就像临阵作战一样。古人药材种类少但每味药的剂量重，这是精锐部队，属于正兵，如飞龙翔鸟，直逼敌军中军。现代人药材种类逐渐增加，但每味药的剂量减轻，这是疑兵，属于奇兵，声东击西，药味越多越好。然而士兵如果不精锐，即使手握奇谋也遇不到合适的战机，就像风后（传说黄帝的大将）突然遇到虎豹般的强敌，奇兵和正兵都难以互相策应，想要乘着骄躁的心态踏足险境，置之死地而后生，可能吗？这里精简了那些才略出众、可备缓急之需的方剂，兼收并蓄并详细注释，仿照张景岳的补、和、攻、散、寒、热、固、因八阵之法，每组列出若干方名，各位医者若能知己知彼，遵循我的言论并谨慎施行，那么处方就能圆融运用，百战百胜了。

[Chapter 8: Eye Halos]
In the dark night, without wind or rain, nor moonlight, how does the eye perceive light on its own? This is because the vigorous Yang Qi surges past the Mingmen (Gate of Life, the source of vital energy), causing the Shen Zhu (Spiritual Pearl, referring to the eyeball/pupil) to reveal its spiritual essence. When reading, the chapters and sentences are distinct; faces of people sitting across the room can be recognized. However, do not rejoice in this double clarity of vision, for the crisis of Qingmang (a condition leading to blindness, such as optic atrophy) is imminent.
This ocular condition manifests as follows: in the absence of lamps or moonlight at night, the eyes flash like lightning, suddenly enabling the perception of objects. Upon closing the eyelids, a band of white light appears horizontally before the eyes, persisting throughout the night without cessation. Even within this white light, one may vaguely perceive the movement of fingers. Senior physicians refer to this phenomenon as "Shen Guang Zi Xian" (Self-appearance of Spiritual Light). This is likely due to the individual's innate constitutional weakness, coupled with a tendency toward excessive activity and internal pathological desires (such as sexual indulgence). After extreme fatigue, overeating, and coitus, the Jing and Blood are severely depleted. The remaining thread of unextinguished True Yang Qi fails to nourish the Yin Water, instead following pathogenic factors upward. Thus, this disease arises. Urgent treatment should involve Da Bu Yuan Jian (Greatly Tonify the Origin Decoction) administered with Jia Jian Ba Wei Wan (Modified Eight-Ingredient Pill) or Zhu Jing Wan (Stabilizing Scenery Pill). If accompanied by restlessness and irritability, temporarily administer Yang Xin Dan (Nourish the Heart Pill) for one or two doses to cause the rootless fire to descend and return to its meridian. Naturally, the Spiritual Light will be contained internally, and the essence will not scatter outward, thereby avoiding the disaster of Qingmang and complications from Wind pathogens.
Pathogenic Qi, turbid and misty, ascends into the eyes. Looking up at the moon, one sees a halo around it like a rainbow. Do not dismiss the moon's appearance as merely a celestial matter; why does a similar halo appear around lamp lights?
This eye condition presents no severe organic pathology. However, when viewing lamps, the moon, or light leaking through gaps, a ring-shaped shadow about the size of a bowl appears outside the visual field. Its color is cyan-red inside and purple-green outside, resembling the corona of the sun or moon, hence termed "Mu Yun" (Eye Halo). The general mechanism is that Kidney Water is deficient and unable to control Heart Fire. The mutual conflict between Water and Fire causes turbulent Qi to surge upward, creating phenomena out of nothing. This is analogous to the interaction between sunlight and rain, which suddenly forms a rainbow, displaying alternating red and green colors. Zhu Xi (Zhu Huiweng) stated that rainbows are caused by the excessive Qi of heaven and earth, and noted that rain stops when a rainbow appears. Is this not a sign of deficient Water, excess Fire, and the deviation of Yin and Yang? Whenever a person is extremely fatigued, strains their vision for long periods, deprives themselves of sleep, and forces themselves to rise, this defect occurs. It may happen temporarily but should not become chronic. Treatment requires Si Jun Zi Tang (Four Gentlemen Decoction) combined with Bu Shui Ning Shen Tang (Tonify Water and Calm Spirit Decoction) for immediate cure, or Ping Qi He Zhong Tang (Regulate Qi and Harmonize Middle Decoction) for one or two doses, which is also effective. If this minor ailment is ignored and no nourishing care is provided, it becomes a precursor to blindness. As the saying goes: "If you do not pluck the sprout, an axe will soon be needed." Be cautious.
Prescribing formulas is akin to engaging in battle. In ancient times, the variety of herbs was small, but the dosage of each was heavy; this constitutes elite troops and orthodox formations (Zheng Bing), advancing directly like flying dragons or soaring birds to strike the enemy's center. Today, the variety of herbs has increased, while dosages have decreased; this constitutes deceptive troops and unconventional formations (Qi Bing), feinting east while striking west, where more ingredients are considered better. However, if the soldiers are not elite, even holding strategic advantages yields no opportunity. Just as Feng Hou (a legendary general of the Yellow Emperor) suddenly encounters enemies as fierce as tigers and leopards, both orthodox and unconventional tactics fail to support each other. Can one hope to survive by stepping into danger driven by arrogance, placing oneself in a death ground and expecting to live? Here, I have selected those prescriptions with proven efficacy for emergencies, providing detailed annotations. I have imitated Zhang Jingyue’s Eight Formations (Bu/Tonify, He/Harmonize, Gong/Attack, San/Disperse, Han/Cold, Re/Heat, Gu/Solidify, Yin/Cause), listing several formula names for each group. May all practitioners know themselves and their adversaries, follow my words, and practice them cautiously. Then, the application of formulas will be flexible and round, ensuring victory in every battle.
