青盲者，谓眼本无异，瞳子黑白分明，直不见物耳。但五脏六腑之精气，皆上注
于目，若脏虚有风邪痰饮乘之，有热则赤痛，无热但内生鄣，是腑脏血气不荣于睛，故外
状不异，只不见物而已。是之谓青盲。
《养生方》云∶勿塞故井及水渎，令人耳聋目盲。
又云∶正月八日沐浴，除目盲。
白黑二晴无有损伤，瞳子分明，但不见物，名为青盲，更加以风热乘之，气不外泄，蕴
积于睛间，而生翳似蝇翅者，覆瞳子上，故为清盲翳也。
夫目是五脏六腑之精华，宗脉之所聚，肝之外候也。腑脏虚损，为风邪痰热所乘，气传
于肝，上冲于目，故令视瞻不分明，谓之茫茫也。凡目病，若肝气不足，兼胸膈风痰劳热，
则目不能远视，视物则茫茫漠漠也。若心气虚，亦令目茫茫，或恶见火光，视见蜚蝇黄黑也
诊其左手尺中脉，沉为阴，阴实者目视茫茫。其脉浮大而缓者，此为逆，必死。其汤熨
针石，别有正方，补养宣导，今附于后。
《养生方·导引法》云∶鸡鸣欲起，先屈左手啖盐指，以指相摩，咒曰∶“西王母
女，名曰益愈，赐我目，受之于口。”即精摩形。常鸡鸣二七着唾，除目茫茫，致其精光，彻
视万里，遍见四方。咽二七唾之，以热指摩目二七，令人目不瞑。
人有昼而睛明，至瞑则不见物，世谓之雀目。言其如鸟雀，瞑便无所见也。
青盲，是指眼睛外观原本没有异常，黑眼珠与白眼珠黑白分明，只是看不见东西罢了。因为五脏六腑的精气，都向上灌注于眼睛，如果脏腑虚弱，风邪、痰饮趁机侵袭，有热邪则出现红肿疼痛，无热邪则仅在内部产生阻滞，这是脏腑气血不能滋养眼球，所以外部形状没有异样，只是看不见东西而已。这就叫做青盲。
《养生方》说：不要堵塞旧井和水沟，这会导致人耳聋目盲。
又说：正月初八日沐浴，可以治疗目盲。
白眼球和黑眼球都没有损伤，瞳仁清晰分明，只是看不见东西，称为青盲；如果再受到风热侵袭，气机不能向外宣泄，郁积在眼球之间，生成像苍蝇翅膀一样的翳障，覆盖在瞳仁上，所以称为青盲翳（此处原文作“清盲翳”，通“青”）。
眼睛是五脏六腑精华所在，是众多经脉汇聚之处，也是肝脏的外候。如果脏腑虚损，被风邪、痰热所侵袭，病气传至肝脏，向上冲逆至眼睛，就会导致视物模糊不清，称之为“茫茫”。凡是眼病，如果是肝气不足，兼有胸膈部的风痰和劳热，就会看不清远处的东西，看事物时感到模糊一片。如果是心气虚弱，也会导致眼睛视物模糊，或者厌恶见到火光，看到空中飞舞的黑点或黄黑色物体（即飞蚊症）。诊察左手尺部脉象，沉脉属阴，阴实者会出现视物模糊。如果脉象浮大而缓，这是逆证，必然死亡。关于汤药、熨法、针刺、砭石等治疗方法，另有专门的方剂，补养和导引的方法，现在附在后面。
《养生方·导引法》说：鸡鸣时分想要起床时，先弯曲左手食指蘸盐，用两指相互摩擦，念咒语说：“西王母的女儿，名叫益愈，赐给我明亮的眼睛，我将它吞入口中。”然后仔细按摩身体。经常模仿鸡鸣叫两次后吞咽唾液，可以消除视物模糊，使目光精亮，看清万里之外，遍见四方。吞咽十四次唾液，用热手指按摩眼睛十四次，能让人眼睛不闭合（保持清醒/明亮）。
有的人白天眼睛明亮，到了晚上就看不见东西，世人称之为雀目。说是像鸟雀一样，天黑后就什么都看不见了。
Qingmang (Green Blindness) refers to a condition where the eyes appear normal externally, with clear distinction between the iris and sclera, yet the patient is unable to see objects. This occurs because the essence and qi of the five zang organs and six fu organs all ascend to nourish the eyes. If the zang and fu are deficient, wind pathogens, phlegm, and fluid retention may invade. If there is heat, redness and pain occur; if there is no heat, internal obstruction arises internally. This indicates that the blood and qi of the zang and fu fail to flourish and nourish the eyeballs. Consequently, although the external appearance remains unchanged, vision is lost. This is termed Qingmang.
The *Yangsheng Fang* (Prescriptions for Nourishing Life) states: Do not block old wells or water ditches, as this can cause deafness and blindness in humans.
It further states: Bathing on the eighth day of the first lunar month can cure blindness.
When both the white and black parts of the eye are undamaged and the pupil is distinct, but vision is absent, it is named Qingmang. If additionally affected by wind-heat, the qi fails to disperse outward, accumulating within the eye, generating an opacity resembling a fly's wing that covers the pupil. Thus, it is called Qingmang Yi (Opacity of Green Blindness).
The eyes are the essence of the five zang and six fu organs, the gathering place of the major meridians, and the external manifestation of the Liver. When the zang and fu are deficient and damaged, they are invaded by wind pathogens, phlegm, and heat. The pathogenic qi transmits to the Liver and rushes upward to the eyes, causing blurred vision, referred to as "Mangmang" (blurred/vague). In general, ocular diseases caused by insufficient Liver qi, combined with wind-phlegm and labor-induced heat in the chest and diaphragm, result in the inability to see distant objects, perceiving everything as vague and indistinct. If Heart qi is deficient, it also causes blurred vision, aversion to firelight, or seeing flying insects and yellow-black spots (floaters). Palpating the pulse at the left cun-guan-chi position: a deep pulse indicates Yin; excess Yin results in blurred vision. A floating, large, and slow pulse is a counter-indication (Ni), indicating certain death. Treatments involving decoctions, moxibustion/warming, acupuncture, and stone therapy have separate specific formulas. Methods for tonification, nourishment, and Daoyin (guiding and pulling exercises) are attached below.
The *Yangsheng Fang · Daoyin Fa* (Guiding and Pulling Methods) states: At cockcrow, when preparing to rise, bend the index finger of the left hand, dip it in salt, rub the fingers together, and recite the mantra: "Daughter of the Queen Mother of the West, named Yiyu, bestow upon me eyes, I receive them into my mouth." Then meticulously massage the body. Frequently, after imitating the crowing of a rooster twice, swallow saliva to eliminate blurred vision, refine the light of the eyes, enable clear vision over ten thousand li, and see all directions. Swallow fourteen portions of saliva, and rub the eyes with warm fingers fourteen times, ensuring the eyes remain open and bright.
Some individuals have clear vision during the day but cannot see objects at night. The world calls this Que Mu (Sparrow Eye/Night Blindness). It is said that like sparrows, they see nothing once darkness falls.
