天空有六种外邪，即风、寒、暑、湿、燥、火；人体有七种内伤情志，即喜、怒、悲、思、忧、恐、惊。七种情志在体内召唤病邪，六种外邪在体外随之侵袭，如果这种内外合邪的情况持续不停，随着情志的感召而发病，这就是心火乘袭肺金（心火过旺克制肺脏）、肾水衰弱反而被火反制的根本原因。世人普遍知道眼睛发红是热证的表现。然而，如果不仔细辨别发红的程度和类型，治疗方法各不相同。有的白睛（巩膜）纯红如火，热气逼人，这是淫热反克（火热之邪过度克制肺金）的病证，治疗参照“淫热反制”的方法。有的白睛红白相间且肿胀，眼睑虚浮，这是风热不制（风热邪气亢盛无制）的病证，治疗参照“风热不制”的方法。有的白睛淡红，脉象细深且呈红色，纵横交错贯穿，这是由七情失调、五贼（指五脏之气受邪或劳损）、劳役过度、饥饱失常引起的病证，治疗参照“七情五贼劳役饥饱”的方法。有的白睛不肿不胀，突然像被血贯穿一样，这是血液被邪气战胜，凝滞而不运行的病证，治疗参照“血为邪胜凝而不行”的方法。有的白睛微微变青，黑睛（角膜）稍带白色，在白睛和黑睛之间，有一圈赤色如环状，称为抱轮红（环绕黑睛的红血丝），这是邪火乘袭肺金、肾水衰弱被火反制的病证。这种病可能是因为眼病日久，情绪抑郁不畅；或者因为眼病时误服过多寒凉药物；或者因为患病期间房事过度，这些都能内伤元气。元气一旦虚弱，心火就会亢盛，所以火能克制肺金。肺金属于手太阴肺经，白睛归属于肺；肾水属于足少阴肾经，黑睛归属于肾。正常情况下水能克制火，但肾水衰弱不能克制心火，反而受到心火的制约，所以视物不明，视线模糊如同在雾露之中，或者眼球高低不平，颜色像死肉一样，毫无光泽，伴有红色的环带围绕黑睛。如果有口干舌苦、眼屎多且涩痛、稍有发热症状的，以还阴救苦汤为主方，黄连羊肝丸为主方，川芎决明散为主方。如果没有口干舌苦、眼屎多且涩痛症状的，以助阳活血汤为主方，神验锦鸠丸为主方，万应蝉花散为主方。无论有无发热，都服用《千金方》中的磁朱丸，以镇坠心火，滋益肾水，荣养元气，自然能够痊愈。唉！天上的六种外邪，未必能伤害人。只有人因为七情召唤才导致生病。如果七情隐匿不召，六邪从哪里跟随而来？反过来做到这一点的人，岂止是能够躲避而已啊！还应当通过修养身心来最终达到这一境界。
The heaven has six pathogenic factors (Six Evils), namely Wind, Cold, Summerheat, Dampness, Dryness, and Fire; the human body has seven emotions (Seven Emotions), namely Joy, Anger, Sorrow, Thought, Worry, Fear, and Fright. When the Seven Emotions summon pathogens internally, and the Six Pathogenic Factors follow externally, if this continuous invasion occurs, diseases manifest according to the emotional summons. This is the origin of Heart Fire encroaching upon Lung Metal (Xin Huo Cheng Jin) and Kidney Water declining and being counter-controlled by Fire. It is commonly known that red eyes indicate Heat. However, without carefully examining the degree and type of redness, treatments vary. If the sclera (Bai Jing) is purely red like fire with intense heat radiating, it is a disease of excessive Heat counter-controlling (Yin Re Fan Ke); treat as described under "Excessive Heat Counter-Controlling." If the sclera is mixed red and white with swelling and flaccid puffiness of the eyelids, it is a disease of uncontrolled Wind-Heat (Feng Re Bu Zhi); treat as described under "Uncontrolled Wind-Heat." If the sclera is pale red with fine, deep-red vessels crisscrossing, it is a disease caused by the Seven Emotions, Five Thieves (Wu Zei - referring to pathological states of the five zang organs), overwork, and irregular diet; treat as described under "Seven Emotions, Five Thieves, Overwork, and Irregular Diet." If the sclera is neither swollen nor distended but suddenly appears streaked with blood, it is a disease where Blood is overcome by pathogens, coagulating and failing to circulate; treat as described under "Blood Overcome by Pathogens and Coagulation." If the sclera slightly turns bluish-green, the cornea (Hei Jing) takes on a whitish hue, and between the sclera and cornea, there is a red ring, termed Bao Lun Hong (Red Ring Encircling the Cornea), this is a disease of Evil Fire encroaching upon Lung Metal and Kidney Water declining to be counter-controlled by Fire. This condition may arise from long-standing eye disease causing depression and stagnation of spirit, or from excessive intake of cold-natured herbs during treatment, or from sexual excess during illness, all of which damage Yuan Qi (Primordial Qi). Once Yuan Qi is deficient, Heart Fire becomes hyperactive, thus allowing Fire to control Metal. Metal refers to the Hand-Taiyin Lung Meridian, and the sclera belongs to the Lung; Water refers to the Foot-Shaoyin Kidney Meridian, and the cornea belongs to the Kidney. Normally, Water controls Fire, but when Kidney Water is deficient and cannot control Fire, it is instead controlled by Fire. Consequently, vision becomes unclear, blurred as if in fog or dew, or the eyeballs become uneven in height, appearing lifeless and lusterless, accompanied by a red band encircling the cornea. If accompanied by dry mouth, bitter taste, excessive ocular discharge, astringency, and slight fever, the primary formulas are Huan Yin Jiu Ku Tang (Return to Yin and Save from Distress Decoction), Huang Lian Yang Gan Wan (Coptis and Sheep Liver Pill), and Chuan Xiong Jue Ming San (Ligusticum and Cassia Powder). If absent are dry mouth, bitter taste, excessive discharge, and astringency, the primary formulas are Zhu Yang Huo Xue Tang (Assist Yang and Invigorate Blood Decoction), Shen Yan Jin Jiu Wan (Divine Efficacy Golden Turtledove Pill), and Wan Ying Chan Hua San (Ten Thousand Responses Cicada Flower Powder). Regardless of the presence or absence of fever, Qian Jin Ci Zhu Wan (Magnetite and Cinnabar Pill from the Essential Prescriptions of a Thousand Gold) should be taken to subdue Heart Fire, nourish Kidney Water, and enrich Yuan Qi, leading to natural recovery. Alas! The six external pathogenic factors of heaven do not necessarily harm humans. It is only through the summoning effect of the seven emotions that harm occurs. If the seven emotions remain hidden and do not summon, how can the six pathogens follow? Those who reverse this process do more than merely avoid danger; they must cultivate themselves to achieve this state.
