Night blindness is loss of vision in the evenings. During the day a person sees, but by the end of the day the vision weakens. The reason for this is one of the moisture of the eye and its thickening, or the moisture of the optic pneuma and its thickening. Night blindness occurs more often in those with black eyes than in those with blue eyes, and in those with a narrow pupil rather than in those with a wide one, and also in those who have eyes, for this indicates the paucity of the pneuma from birth. Sometimes this state of vision occurs as a result of some disease of the eye itself, and sometimes the stomach and brain are involved. This will be recognized by the signs that you already know.
Treatment. If there is an abundance of blood in the patient, the blood should be drained from the mullet and from the vessels in the inner corners of the eyes, and also use other known emptying agents, and more than once. Sometimes emptying is done with the help of scammonium and beaver stream, this helps. Before meals, the patient is given hyssop syrup or hyssop and dry rue in powder form and allowed to drink a little old wine after complete digestion. Tested remedies include juice from goat liver, stabbed with a knife and suspended over coals. When the juice begins to ooze from it, it is collected, sprinkled with Indian salt and long pepper and smeared on the eyes. Sometimes they sprinkle the same drugs on the liver while it is still fried, bend over its steam and eat the fried liver - all this is very useful. Sometimes the liver is cut into wide strips and placed in layers - a layer of long pepper, a layer of liver - and fried in tannur, but not much. Then remove, strain out the juice and lubricate your eyes with it. The same is done with hare liver.
Long pepper ointment and ointment work in the same way, which is prepared as follows: take long pepper, black pepper and kamala in equal parts and apply this to the eye. Bile is also good, especially the bile of goats and mountain sheep. An ointment made from balsam oil, weakened by a small amount of opium, is also good. Rubbing three types of pepper, ground into powder, as well as Egyptian alum, helps a lot. Lubricating with honey and fennel juice also works well, after which you need to keep your eyes closed for a long time. Honey has an even stronger effect when alum or ammonia is added to it. Lubricating with the blood of animals with a hot nature also helps, as well as smearing with the squeezed juice of a mad cucumber, weakened by purslane seeds. Potash ointment and verdigris ointment, as well as monitor lizard and skink feces are also useful. They also take one part of kid’s bile, two parts of pepper, three parts of usshak, mix it with honey and use it. Bleeding from the vessel of the inner corners of the eye is also useful.
