Yuan Yi presents as a round opacity in the center of the black pupil, appearing small under bright daylight and dark in dim light. Initially, only the outline is visible without sensation, but eventually, it brings disaster, entangling the eyes. Treat with Bu Gan San (Liver-Nourishing Powder) and Bu Shen Wan (Kidney-Nourishing Pill). If cold-natured medicines are mistakenly administered, the disease will be further aggravated. This condition arises from deficiency and emptiness of the Liver and Kidney. Physicians must seek the cause meticulously and not remain ignorant.
This is a condition of Wind-Deficiency in the Liver and Kidney; when applying eye drops to remove opacities, one should consider avoiding cold medicines. It is suitable to take Wu Zi Wan (Five-Seed Pill), Fu Shou San (Hand-Wiping Powder), Jin Jiu Wan (Brocade Dove Pill), and Yan Dian Wan (Rock Lightning Pill).

Bing Yi is solid and hard like frozen ice; whether observed in shade or sunlight, tears flow profusely. A white membrane invades the interior of the eye at all times, causing unbearable pain and bitter suffering. Treat with Tong Gan San (Liver-Penetrating Powder) and regulate the Heart [region/meridian]; this is named Dan Qi Ku Gan Chan (Gallbladder Qi suffering from Liver Qi entanglement). A good physician uses medicine without error or fear, restoring brightness to the eyes better than before.
This is due to long-term deficiency of the Liver and Kidney, with persistent Wind-Heat causing chronic pain. The treatment should focus on regulating the Liver and Kidney; this is an opacity generated by the coagulation of hot tears. It is suitable to take Yan Dian Wan (Rock Lightning Pill), San Hua Wu Zi Wan (Three-Flowers Five-Seed Pill), and Bo Yun San (Cloud-Dispelling Powder).

Song Ci: Xijiang Yue
Why is Hua Yi still considered stable? It slightly contains yellow color and lacks foundation. White opacity, resembling quicksilver, penetrates and covers the pupil, restraining the restless mind. Liver and Lung Wind-Heat interfere with each other; the absence of pain is auspicious. Taking Huan Jing San (Eye-Recovery Powder) is the correct path; the tune is set to "Xijiang Yue".
This is due to Wind-Deficiency in the Liver and Kidney, with internal Heat failing to dissipate. After prolonged exposure to five types of Wind-Heat toxins, if left untreated, one will sink into eternal darkness. It is suitable to take Fu Shou San (Hand-Wiping Powder), San Hua Wu Zi Wan (Three-Flowers Five-Seed Pill), and Yan Dian Wan (Rock Lightning Pill).
