[0002] The slit lamp is a commonly used examination device in ophthalmology. It forms a strip-shaped beam of strong light through a slit, and then observes it through a microscope system. It can conduct a detailed examination of the structure of the eye, including the cornea, conjunctiva, iris, lens, etc., which helps doctors detect eye diseases and make diagnoses and evaluations.

[0003] When a slit lamp is used to examine a patient's eyes, the distance between the operating medical staff and the patient is relatively close, and there is no barrier in between, which can easily cause cross infection. At the same time, in cold seasons, the hot air exhaled by the patient can easily cause the lens to blur. In order to solve this problem, Chinese utility model patent CN213075608U discloses a baffle suitable for a slit lamp, which is arranged on the headrest of the slit lamp. The baffle is provided with an opening blocked by a drawer plate, so that the patient's mouth and nose can be blocked by the baffle. However, the eye heights of different people are different. When the patient's chin is placed on the chin rest for eye examination, the height of the baffle needs to be adjusted so that the patient's eyes are located at a suitable position of the opening on the baffle. However, the above patent is not very convenient for adjusting the height of the baffle. Utility Model Content
