PROBLEM TO BE SOLVED: To provide a non-contact tonometer capable of actually measuring the hardness of a cornea. SOLUTION: This non-contact tonometer provided with a nozzle 12 for spraying air current to specimen cornea C and a cornea deformation detecting means for detecting designated deformation of the cornea C. The tonometer is provided with a cornea deformation detecting optical system 50 for detecting designated deformation of only the surface of the cornea C. |
