A lens meter capable of obtaining optical characteristics of a lens with high stability and accuracy has a measurement optical system including a target panel having measurement targets having first measurement targets and second measurement targets and a photodetector which photo-receives a measurement light bundle, a calculation means which calculates the optical characteristics including first calculation means which calculates first optical characteristics based on a detection result of the first measurement targets by the photodetector and second calculation means which calculates second optical characteristics based on a detection result of the first and second measurement targets, and display control means which displays the second optical characteristics as the optical characteristics of the lens if the calculation result by the first calculation means or the detection result by the photodetector satisfies a predetermined condition and displays the first optical characteristics if the predetermined condition is not satisfied.
