PROBLEM TO BE SOLVED: To provide an optometer acquiring information useful for observation and diagnosis of the corneal edema.SOLUTION: An optometer 1 includes: an irradiation optical system 10 for applying first measurement light and reference light to the cornea of a subjects eye and a photodetector optical system 20 including a photodetector 22 for receiving corneal reflex light of the first measurement light and corneal reflex light of the reference light. Further the optometer 1 causes a control part to acquire moisture content distribution information related to distribution of a two-dimensional moisture content in the cornea on the basis of intensity of reflected light of the first measurement light and intensity of reflected light of the reference light detected by the photodetector 22.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2016,JPO&INPIT【課題】角膜浮腫の観察および診断に役立つ情報を取得する検眼装置を提供すること。【解決手段】検眼装置1は、被検眼の角膜に第1測定光と参照光とを照射する照射光学系10と、第1測定光の角膜反射光および参照光の角膜反射光を受光する受光素子22を備える受光光学系20と、を備えている。また、検眼装置1は、受光素子22によって検出された第1測定光の反射光の強度と参照光の反射光の強度とに基づいて、角膜における二次元的な水分量の分布に関する水分量分布情報を、制御部によって取得する。【選択図】図1
