见黑白花者，因偏正头疼，日久有此症，内障之
实也。初病时，视觉微昏，渐睹空中有黑花，如垂蚁、
悬珠、蝇飞、蝶舞，如银钉、银丝、水银珠子，连串
不断；形如扫帚，如罗网，如屋上灰尘，结线数条不
断；又如扬场麦糠，尘土自天而下，结成黑白一定花
样∶遂眼珠不定，远看则大，近看则小。因循日久，
翳遮瞳人，不见阳光。宜用孙真人吹冲之法，揭尽肝、
肺凝结翳膜，方有补益，若泛投除风散热、滋补肾水
之药、百无一效者也。外无云翳不点。
人有自见神光，眼前如电光闪掣，甚如火焰霞明，
时发时止，与瞻视有色之一定者不同。此乃阴精亏
损，孤阳飞越，而神光欲散，久则失明。宜补肾水、
宁心神。火不妄动，光自消除矣。宜服生、熟地各二
钱，白芍、当归、麦冬、茯神各一钱五分，五味子三
十粒，生甘草六分。水煎空心温服。不宜点。
此症谓夜间开目，倏忽看见火光，如灯头、香
头，时有时无，金黄撩乱。此肾水不足，虚火上炎，
以致目之神光失序，荡扬不定耳！宜服地黄丸，原分
两，加辽五味烘干两半，肉桂去皮、不见火一两。蜜
丸桐子大。每服三钱，空心盐汤下。不点。
神膏，即睛珠中包涵瞳神者，外有坚壳数重，中
则清脆，内包黑稠神膏一函是也。
神水者，由三焦发源，先天真一之气所化，在目
中不可见也。
神光者，目中自视之精华，原于命门，通于胆，
发于心，火之用事也。
真血者，肝中升运于目，轻清之血，乃滋目经络
之血也。
真气者，目络往来生动之气，乃先天真一发生之
原阳也。
真精者，先、后二天元气所化之精汁，先起于肾，
次施于胆，而后及乎瞳神也。
凡此数者，皆滋目津液。人少壮，滋目之液盛，
则目明；衰老，滋目之液减，则目昏暗。往往见治者，
针刺血出，以致伤目。岂知目中有神膏、神水、神光、
真血、真气、真精为何物乎？愚者欣受而不悟，可叹
可叹！
看见黑白花影的人，是因为偏头痛或正头痛，日久形成此症，属于内障实证。初发病时，视力轻微昏花，逐渐看到空中有黑花，形状像垂下的蚂蚁、悬挂的珍珠、苍蝇飞舞、蝴蝶起舞，又像银钉、银丝、水银珠子，连绵不断；形状像扫帚，像罗网，像屋顶上的灰尘，结成几条不断的线；又像是扬场时的麦糠，尘土从天而降，结成黑白固定的花样：于是眼珠转动不定，远看则大，近看则小。拖延日久，翳膜遮蔽瞳人，看不见阳光。适宜使用孙真人吹冲的方法，揭开肝、肺凝结的翳膜，之后才有补益的机会，如果随意投用祛风散热、滋补肾水的药物，百无一效。外部没有云翳的不宜点药。
有人自见神光，眼前如电光闪烁，甚至如火焰霞光般明亮，有时发作有时停止，与注视有色且固定的物体不同。这是阴精亏损，孤阳飞越，导致神光欲散，久了就会失明。适宜补肾水、宁心安神。火不妄动，光自然消除。适宜服用生地黄、熟地黄各二钱，白芍、当归、麦冬、茯神各一钱五分，五味子三十粒，生甘草六分。用水煎煮，空腹温服。不宜点药。
此症指夜间睁眼，忽然看见火光，像灯头、香头，时有时无，金黄杂乱。这是肾水不足，虚火上炎，导致眼中神光失序，动荡不定罢了！适宜服用地黄丸，按原分量，加入辽五味烘干一两半，肉桂去皮、不见火（即不直接火烧）一两。蜜丸如梧桐子大。每次服用三钱，空腹盐汤送下。不点药。
神膏，就是包裹在睛珠中涵盖瞳神的物质，外层有几重坚硬的壳，中间则清脆，内部包裹着一函黑稠的神膏。
神水，由三焦发源，是先天真一之气所化，在眼中不可见。
神光，是眼中自我视物的精华，源于命门，通达于胆，发于心，属火的作用。
真血，是从肝脏升运到眼睛的，轻清之血，是滋养眼部经络的血。
真气，是眼部络脉往来生动的元气，是先天真一发生之源的原阳。
真精，是先、后天二天元气所化的精汁，先起于肾，其次施用于胆，然后才及于瞳神。
凡此几种，都是滋养眼睛的津液。人年少壮实，滋养眼睛的津液旺盛，则眼睛明亮；衰老时，滋养眼睛的津液减少，则眼睛昏暗。往往见到治疗者，针刺出血，以致伤害眼睛。哪里知道眼中有神膏、神水、神光、真血、真气、真精是什么东西呢？愚者欣然接受却不醒悟，可叹可叹！
Those who see black and white floral patterns suffer from this condition due to long-standing lateral or frontal headaches, representing a solid excess pattern of internal cataract (internal eye disease). At the onset, vision is slightly blurred; gradually, one perceives black spots in the air, resembling hanging ants, suspended pearls, flying flies, or dancing butterflies, as well as silver nails, silver threads, or mercury beads, continuous and unbroken; shapes like brooms, nets, or dust on roofs forming several unbroken lines; or like chaff winnowed in the wind, with dust falling from the sky, forming fixed black and white floral patterns. The eyeball becomes unstable, appearing larger when viewed from afar and smaller up close. If neglected for a long time, opacity (cataract) covers the pupil, blocking sunlight. It is appropriate to use Sun Simiao’s blowing and flushing method to remove the opacity condensed in the Liver and Lung meridians before applying tonification. Blindly administering drugs for dispelling wind and clearing heat, or nourishing Kidney water, will yield no effect. External application is not indicated unless there is an external nebula.
Some individuals perceive "divine light" spontaneously, seeing flashes like lightning or bright flames and rosy clouds in front of their eyes, which come and go intermittently. This differs from gazing at fixed colored objects. This condition arises from the deficiency of Yin essence, causing solitary Yang to fly away, leading to the dissipation of divine light; if prolonged, it results in blindness. Treatment should focus on nourishing Kidney water and calming the Heart spirit. When fire does not move recklessly, the light will naturally subside. One may take Sheng Di Huang (Raw Rehmannia Root) and Shu Di Huang (Prepared Rehmannia Root), each 2 qian; Bai Shao (White Peony Root), Dang Gui (Angelica Sinensis), Mai Dong (Ophiopogon Tuber), and Fu Shen (Poria with Hostwood), each 1.5 qian; Wu Wei Zi (Schisandra Berry), 30 grains; and Sheng Gan Cao (Raw Licorice Root), 0.6 fen. Decoct in water and take warm on an empty stomach. External application is not indicated.
This symptom refers to suddenly seeing firelight upon opening the eyes at night, resembling lamp wicks or incense tips, appearing intermittently with a chaotic golden hue. This is caused by insufficient Kidney water and deficient fire flaming upward, resulting in disordered and unsettled divine light in the eyes. One should take Dihuang Wan (Rehmannia Pill) according to the original dosage, adding Liao Wu Wei Zi (Liaoning Schisandra Berry), dried and roasted, 1.5 liang, and Rou Gui (Cinnamon Bark), peeled and not directly scorched, 1 liang. Form into honey pills the size of Torreya seeds. Take 3 qian per dose, washed down with salt water on an empty stomach. External application is not indicated.
Shen Gao (Divine Paste) is the substance contained within the lens that encompasses the pupil. It has several layers of hard shell externally, is crisp internally, and contains a cavity of thick, dark Divine Paste.
Shen Shui (Divine Water) originates from the San Jiao (Triple Burner) and is transformed from the primordial Qi of Heaven and Earth; it is invisible within the eye.
Shen Guang (Divine Light) is the essence of vision within the eye, originating from the Ming Men (Gate of Life), connecting to the Gallbladder, issuing from the Heart, and functioning through Fire.
Zhen Xue (True Blood) is the light and clear blood ascended from the Liver to the eyes, which nourishes the ocular collaterals.
Zhen Qi (True Qi) is the dynamic Qi circulating within the ocular collaterals, representing the primal Yang derived from the source of primordial Qi.
Zhen Jing (True Essence) is the refined fluid transformed from the Yuan Qi of both congenital and acquired sources. It begins in the Kidney, spreads to the Gallbladder, and finally reaches the pupil.
All these substances serve to moisten the eye's fluids. In youth and vigor, these ocular fluids are abundant, resulting in clear vision; in old age, they diminish, leading to dim vision. Often, practitioners cause harm by needling until bleeding occurs. How can they know what Shen Gao, Shen Shui, Shen Guang, Zhen Xue, Zhen Qi, and Zhen Jing are? Fools accept this without understanding; truly lamentable!
