To treat flying filaments entering the eye, apply head scurf (Tou Gou) into the eye to remove it immediately; this is miraculous.
For flying filaments entering the eye, apply sap from the *Celtis sinensis* tree (Zhe Shu Jiang), then use cotton wrapped around the tip of a chopstick dipped in water to wipe the eyelid margins to remove discharge and toxins.
Another prescription: For flying filaments entering the eye, take one *he* (a traditional unit of volume) of hemp seeds (*Huo Ma Ren*, 火麻子), crush them, soak and stir in one bowl of well water (Jing Hua Shui), then immerse the tongue in the water so that saliva and foam naturally emerge; this is miraculous.
Yet another prescription: Crush eggplant leaves (*Qie Zi Ye*, 茄子叶); adding hemp seeds makes it even more effective.
Zhu Danxi stated: When flying filaments fall into the eye, causing redness and swelling resembling squinting (Mi Mu, 眯目), pain, astringency preventing opening, and clear nasal discharge. Grind Jingmo (Beijing Ink Stick, 京墨) thickly, apply with a new brush into the eye, keep the eyes closed for a moment, then gently open them with hands; the filament will form a single mass visible on the sclera (Yan Bai, 眼白). Wipe it out gently with cotton to heal. If not completely removed, treat again. For squinting/foreign body sensation, soak salt and fermented soybeans (Chi, 豉) in water; observing the water surface, the debris will float up immediately. (From Sun Simiao's Formula)
*Qian Jin Fang*: To treat rice or wheat awns entering the eye, cover the eye with a new cloth. Rub earthworms (Qi Lao, 蛴螬) over the cloth; the awns will adhere to the cloth.

Another prescription: Apply thickly ground good ink; it removes immediately.
