按∶金井者，在黑睛中间，一个小圈如胡椒大，
是胆汁约束神水，一条黄线。若肾水足，则金井满；
肾水少，则金井亏。神水不足，焉能照物？法当养肝
血以滋胆，清肺金以生水，则愈矣。先吃杞实粥（方
见二卷）、四物汤加枸杞子、五味，地黄汤加枸杞、
五味子。不宜点。
此症由阴精、肾气两衰，相火邪行无制，火热熏
蒸胆汁，胆汁亏损，遂致神光散大。亦有脑疼致瞳
子散大，暴怒致瞳神散大，头风、痰厥致瞳子散大，
食辛辣、炙爆过多致瞳子散大，种种不一。大约因风、
火、气、痰散大者，宜用《元机启微》所载济阴地黄
丸收小，再用地黄明目丸，肾虚散大者，先服四物汤
加枸杞、五味子，次用地黄汤加枸杞、五味子，瞳人
自收小矣。无论虚实，宜服千金磁朱丸，不宜点，
点则失明。
神膏乃目中包涵之膏液也。由胆中精汁积成，涵
养瞳神者。膏中一点黑莹，是肾、胆所聚之精华，
能照万物。如血不滋膏，神膏干矣。故滋膏须以养
肝血为主。白睛有赤丝等症，当清肺火，使不克肝，
肝家无火消耗，于以养血无难矣。先服四物汤，加滋
肾药，次服地黄汤，加养血药；再用地黄明目丸。不
点。
眼见五色花者，内虚也。盖因肾水不足，君、
相二火反来侵水，水火激搏，诸影变幻，随各脏
所受之邪，因脏现形。见黄色者，土之邪火侵也，见
红花者，心之邪火侵也；见青蓝等花者，木之邪火侵
也。如水照物，各有其形。人身中有君火、相火、化
火，群火侵水，总由肾水失散之故。治法急宜收敛
为妙。大约肾经之水，弱不能配火，邪火侵犯肾水，
是以见五色花也。先吃杞实粥，次用四物汤养肝血，
再用地黄汤滋肾水。不点。
按语：金井，位于黑睛（角膜）中央，有一个如胡椒粒大小的小圆圈，这是由胆汁约束神水形成的一条黄线。如果肾水充足，则金井饱满；如果肾水不足，则金井亏损。神水不足，怎么能看清物体呢？治疗方法应当滋养肝血以滋润胆腑，清泻肺金以滋生水源，这样就能痊愈。先服用杞实粥（方剂见第二卷）、四物汤加枸杞子、五味子，地黄汤加枸杞、五味子。不宜使用眼药点治。
此症是由于阴精和肾气双重衰弱，相火（寄居于肝肾的虚火）邪行无法制约，火热熏蒸胆汁，导致胆汁亏损，于是致使神光散大。也有因脑疼导致瞳仁散大的，因暴怒导致瞳神散大的，因头风、痰厥导致瞳仁散大的，因食用辛辣、油炸食物过多导致瞳仁散大的，情况种种不一。大致因风、火、气、痰导致散大的，适宜用《元机启微》所载的济阴地黄丸来收敛缩小，再用地黄明目丸；因肾虚导致散大的，先服用四物汤加枸杞、五味子，随后服用地黄汤加枸杞、五味子，瞳人自然就会收缩变小。无论虚实，都适宜服用千金磁朱丸，不宜点眼药，点了就会导致失明。
神膏是眼中包裹涵育的膏状液体。它由胆中的精汁积聚而成，用来涵养瞳神。神膏中的一点黑色晶莹之物，是肾和胆所汇聚的精华，能够照见万物。如果血液不能滋养神膏，神膏就会干枯。所以滋养神膏必须以养肝血为主。白睛（巩膜）出现赤丝等症状时，应当清泻肺火，使其不克制肝木，肝家没有火气消耗，那么养血就不难了。先服用四物汤，加入滋肾药物，随后服用地黄汤，加入养血药物；再服用地黄明目丸。不点眼药。
眼前看见五色花朵，是内部虚损的表现。大概是因为肾水不足，君火（心火）和相火反过来侵犯肾水，水火相互激荡搏结，各种影像变幻莫测，随着各脏腑所受邪气的不同，依循脏腑显现形状。看见黄色花朵的，是土之邪火侵犯所致；看见红色花朵的，是心之邪火侵犯所致；看见青色、蓝色等花朵的，是木之邪火侵犯所致。就像水照映物体，各有其形。人体中有君火、相火、化火，群火侵犯肾水，总归是因为肾水失散的缘故。治疗方法急宜收敛为妙。大致是肾经之水虚弱，不能与火相配，邪火侵犯肾水，所以会出现看见五色花的情况。先吃杞实粥，随后用四物汤养肝血，再用地黄汤滋补肾水。不点眼药。
According to the commentary: The "Jin Jing" (Golden Well) is located in the center of the black pupil (cornea), appearing as a small circle the size of a peppercorn. It is a yellow line formed by bile constraining the divine water (aqueous humor). If kidney water is sufficient, the Jin Jing is full; if kidney water is deficient, the Jin Jing is depleted. How can one see objects clearly if divine water is insufficient? The treatment method should nourish liver blood to moisten the gallbladder and clear lung metal to generate water source, which will lead to recovery. First, consume Qishi Porridge (formula seen in Volume 2), Siwu Tang (Four Substances Decoction) added with Gouqizi (Lycium Fruit) and Wuweizi (Schisandra Fruit), and Dihuang Tang (Rehmannia Decoction) added with Gouqi and Wuweizi. Eye drops are not suitable.
This condition arises from the dual deficiency of yin essence and kidney qi, allowing ministerial fire (deficient fire residing in the liver and kidney) to act pathogenically without restraint. The heat and fire fumigate the bile, causing bile deficiency, thereby leading to the dispersion of divine light (visual acuity). There are also cases where brain pain causes the pupil to dilate, sudden anger causes the divine spirit (pupil) to dilate, head wind or phlegm syncope causes the pupil to dilate, and excessive consumption of spicy or fried foods causes the pupil to dilate; the situations are varied. Generally, for dilation caused by wind, fire, qi, or phlegm, it is appropriate to use Jiying Dihuang Wan (Nourishing Yin Rehmannia Pill) recorded in *Yuanji Qiwei* to contract it, followed by Dihuang Mingmu Wan (Rehmannia Brightening Eyes Pill); for dilation caused by kidney deficiency, first take Siwu Tang (Four Substances Decoction) added with Gouqizi and Wuweizi, then take Dihuang Tang (Rehmannia Decoction) added with Gouqi and Wuweizi, and the pupil will naturally contract. Regardless of excess or deficiency, it is appropriate to take Qianjin Cizhu Wan (Thousand Gold Magnetite and Cinnabar Pill), but eye drops are contraindicated, as using them may cause blindness.
Shengao (Divine Paste) is the paste-like fluid contained within the eye. It is accumulated from the essence juice of the gallbladder and serves to nourish the divine spirit (pupil). A spot of black luster within the paste is the essence gathered by the kidney and gallbladder, capable of illuminating all things. If blood does not nourish the paste, the divine paste becomes dry. Therefore, nourishing the paste must primarily focus on nourishing liver blood. When red filaments appear on the white sclera, one should clear lung fire to prevent it from overacting on liver wood. If the liver has no fire to consume resources, nourishing blood becomes easy. First, take Siwu Tang (Four Substances Decoction) added with kidney-nourishing herbs, then take Dihuang Tang (Rehmannia Decoction) added with blood-nourishing herbs; subsequently, take Dihuang Mingmu Wan (Rehmannia Brightening Eyes Pill). Do not use eye drops.
Seeing colored flowers before the eyes indicates internal deficiency. This is generally due to insufficient kidney water, causing lord fire (heart fire) and ministerial fire to invade the water. Water and fire clash and contend, causing various images to transform unpredictably, taking shape according to the pathogens received by each zang organ. Seeing yellow flowers indicates invasion by earth's pathogenic fire; seeing red flowers indicates invasion by heart's pathogenic fire; seeing blue or green flowers indicates invasion by wood's pathogenic fire. Just as water reflects objects, each has its form. In the human body, there are lord fire, ministerial fire, and transformation fire. The invasion of multiple fires into the water is ultimately due to the scattering of kidney water. The treatment method urgently requires astringency as the best approach. Generally, the water of the kidney meridian is weak and cannot balance fire; pathogenic fire invades kidney water, hence the appearance of seeing colored flowers. First, eat Qishi Porridge, then use Siwu Tang (Four Substances Decoction) to nourish liver blood, and finally use Dihuang Tang (Rehmannia Decoction) to nourish kidney water. Do not use eye drops.
