PROBLEM TO BE SOLVED: To obtain a highly convenient and safe result of measurement.SOLUTION: An ophthalmologic measuring apparatus includes: a measuring optical system including a projecting optical system for projecting measuring light toward a subjects eyes and a light receiving optical system for receiving the reflection light of the measuring light from the subjects eyes by a light receiving element via a light transmitting member in contact with outside air and an apparatus body for housing the measuring optical system and holding the light transmitting member on the subjects eye side. The ophthalmologic measuring apparatus measures characteristics of the subjects eyes based on output signals from the light receiving element. The ophthalmologic measuring apparatus also includes a dew-condensation removal means for removing dew condensation in the light transmitting member in contact with outside air.
