An air curtain apparatus for ophthalmological inspection instrument comprising an air blower installed on the upper side of the support column of the inspection instrument which generates a downward air flow stream in vertical direction, an air suction device installed on the lower side of the support column for sucking the air flow from the air blower which enables an effect of push and pull on the air flow to effectively remove the air exhaled from the ophthalmological patient and diffused around the inspection instrument when the patient sits in front of the eyes-doctor inspection; and the air flow passing through the air suction device is then guided to the Medical lever Air-suction and Cleaning Equipment for filtration and other effective treatment and then discharged to the atmosphere to prevent from inter-infection of germs and odor through breath of air between the eyes-doctor or nursing worker and the patient due to eyes inspection at close distance.
