Ophthalmology binding device with good air permeability

The utility model relates to the technical field of medical instruments, and provides an ophthalmology binding device with good air permeability, which comprises an elastic binding band and two eyeshades symmetrically fixed at two ends of the elastic binding band. A propelling mechanism is arranged, when medicine is applied to the eyes of a patient, a first rotating ring is rotated to drive a threaded barrel to rotate, a displacement block moves outwards in the threaded barrel, and a medicine liquid sponge slowly gets close to the two eyes till the medicine liquid sponge is attached to the eyes to be in a comfortable state. The liquid medicine sponge can be always attached to the eyes of the patient every time, the eyes are always in a ventilation state due to the fact that the liquid medicine sponge is externally attached to the eyes, the effect of good air permeability is achieved, and the phenomenon of wound deterioration is prevented; an adjusting assembly is arranged, adjusting cylinders at the two ends
