一抹淡淡的晚霞映照眼前，使视线变得明亮；飞舞的苍蝇和蝴蝶仿佛在追逐新晴的天空。为何会出现旗帜般开合卷曲的景象？为何有无尽的丝环状物灭去又重生？饮酒时杯中弓蛇之影早已存在；仰望天空时，萤火般的乱星摇曳闪烁。
如此妖异的气象究竟因何导致？是因为水落（肾阴亏虚）而风腾、火上升（肝火上炎）。
这种眼病没有外在症状，却是无中生有。出现如游丝、结发、飞蝇、舞蝶、蛇旗、绦环等物体的形状，颜色或青黑、粉白、微黄，看起来像是在眼球外的空中飞扬撩乱，瞬间消失又瞬间出现。向上看则影像在上，向下看则影像在下，本学科称之为云雾移睛症（Wuyun Yijing, Cloudy Vision Shifting the Pupil）。这多见于纵情酒色财气的男子，以及失血过多、悲泣思虑愤怒的妇女，情感缠绵，欲望无休止。再加上被风吹袭、日晒，不慎寒暑变化，劳累筋骨，饥饿肌肤，极力劳作，导致真阴元阳几乎败坏殆尽，致使脏腑空虚。
空虚生风，则邪气随风走散而精气耗散；虚弱生火，则痰液因火热凝结而形成病灶。因此出现上述妄见的物色。急需配制既济丸（Jiji Wan, Ji Ji Pill）、还睛夜光丸（Huanjing Yeguang Wan, Huanjing Night-Luminous Pill），早晚同时服用。或者白天调理全真散（Quanzhen San, Quanzhen Powder），晚上煎服全真一气汤（Quanzhen Yiqi Tang, Quanzhen One-Qi Decoction），坚持日月不停，所见之物会逐渐变小并消除。
如果吝惜钱财费用，又亲近酒色花柳，不善于调养身体，那么痰、风、火都会归并于胆和肾两部，导致胆肾受伤而津液更加枯竭。万不能升运精华以滋养化源（生命本源）。那么精明之窠（目窍）和元府（眼中气机出入之门户）不再发挥作用，即使每天接受清纯的水谷之气，也未必能恢复其天性。岁月长久，神水（眼中清澈液体）遂凝结而成翳（Yi, Opacity/Cataract），隐隐遮蔽于轮内，称为内障（Neizhang, Internal Cataract）。
这就好比冰池雪涧，虽然清澈，但如果没有任何活水流注灌溉，就会浑浊并滋生苔藓，这是形势与道理上必然的结果。《龙木论》认为胃脑脂流下作翳，是不正确的。大凡病情发展到内障阶段，即使擅长八法神针治疗，可治愈的只有十分之一四，不可治愈的有十分之一六。所谓药物只能治疗假病，针灸救不起残废的眼疾。其视觉表现如同萤火虫、灯光、闪电划过霞光，等到失明，多属于青盲风变（Qingmang Fengbian, Blindness due to Wind Transformation）之列。即使侥幸形成障蔽，施针也未必令人满意。
如果久立久视，一时昏花，以及鞠躬、拾物、蹲踞后起身时头晕眼花，萤星闪烁，甚至眼前漆黑，稍停片刻才恢复正常，这也是情欲消耗精气所致。因此稍微感到烦劳，就会导致水火不交（心肾不交），神光（视力/精神之光）摇动。年形虽然强壮，这也叫做菁华渐减，仍然服用上述药物。如果不这样，八味丸（Bawei Wan, Eight-Ingredient Pill）、加减八味丸（Jiajian Bawei Wan, Modified Eight-Ingredient Pill）尤为恰当。
A faint glow of evening clouds illuminates the eyes; flying flies and dancing butterflies seem to chase the new clear sky. Why do banners appear to open and roll? Why are endless silk rings extinguished and reborn? The shadow of a bow in a cup of wine has already existed; gazing at the sky, firefly-like chaotic stars flicker and shake.
What causes such demonic phenomena? It is because water recedes (Kidney Yin deficiency) while wind rises and fire ascends (Liver Fire hyperactivity).
This eye condition presents no external symptoms, yet it arises from nothingness. Manifestations include shapes resembling wandering threads, knotted hair, flying flies, dancing butterflies, snake flags, and ribbon rings. Colors may be cyan-black, pinkish-white, or slightly yellow. They appear to flutter chaotically in the air outside the eyeball, vanishing and reappearing instantly. Looking up makes them appear higher; looking down makes them appear lower. This discipline refers to this as Wuyun Yijing (Cloudy Vision Shifting the Pupil). This condition commonly affects men who indulge in alcohol, lust, wealth, and anger, as well as women who have lost excessive blood or suffer from weeping and resentful thoughts. Their emotions linger, and desires know no rest. Compounded by exposure to wind and sun, negligence regarding cold and heat, fatigue of sinews and skin, and extreme labor, the True Yin and Primordial Yang are nearly exhausted, leading to emptiness in the Zang-Fu organs.
Emptiness generates wind, causing pathogenic factors to scatter with the wind and essence to dissipate; deficiency generates fire, causing phlegm to coagulate due to heat and form lesions. Thus, the aforementioned hallucinations occur. Urgently prepare Jiji Wan (Ji Ji Pill), Huanjing Yeguang Wan (Huanjing Night-Luminous Pill), and administer them morning and evening simultaneously. Alternatively, regulate with Quanzhen San (Quanzhen Powder) during the day and decoct Quanzhen Yiqi Tang (Quanzhen One-Qi Decoction) at night. Persisting without interruption over days and months, the perceived objects will gradually diminish and disappear.
If one is stingy with money and expenses, yet continues to indulge in alcohol and flowers, failing to nourish oneself properly, then phlegm, wind, and fire will all converge into the Gallbladder and Kidney regions. Injury to the Gallbladder and Kidneys leads to further depletion of body fluids. Essence cannot ascend and circulate to nourish the source of transformation (the root of life). Consequently, the cavity of clarity (eye aperture) and Yuan Fu (gateways for Qi movement in the eye) cease to function. Even if pure Qi from water and grain is ingested daily, natural function may not be restored. Over time, Shen Shui (clear fluid in the eye) condenses into Yi (opacity/cataract), subtly obstructing the interior of the wheel, termed Neizhang (Internal Cataract).
This is like an icy pool or snowy stream: although clear, without flowing water to irrigate it, it becomes turbid and grows moss; this is inevitable according to circumstances and principle. The assertion in *Longmu Treatise* that "gastric brain fat flows down to form cataracts" is incorrect. Generally, when the disease progresses to internal cataracts, even if skilled in the Eight Methods of Divine Needle therapy, only 14% are curable, while 60-70% are incurable. It is said that medicine can treat false illnesses, but needles cannot revive ruined vision. Visual manifestations resembling fireflies, lamps, or lightning flashing through clouds, progressing to blindness, mostly fall under the category of Qingmang Fengbian (Blindness due to Wind Transformation). Even if a cataract fortunately forms, needling may not yield satisfactory results.
Standing or gazing for long periods causing temporary blurriness, or experiencing dizziness and blurred vision with flickering stars upon rising from bending, picking up objects, or squatting, or even temporary blackouts before recovery, are also caused by the consumption of essence and Qi through emotional and sexual excess. Therefore, slight fatigue leads to the failure of Water and Fire interaction (Heart-Kidney non-interaction), causing Shen Guang (visual spirit/light) to tremble. Although the physical constitution appears robust, this is called gradual decline of Jing Hua (essence and brilliance). Continue taking the aforementioned medicines. If not, Bawei Wan (Eight-Ingredient Pill) or Jiajian Bawei Wan (Modified Eight-Ingredient Pill) are particularly appropriate.
