Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a subjective optometer capable of performing a subjective examination easily and accurately.SOLUTION: A subjective optometer includes: a first light source for illuminating one eye of a right and left pair of eyes to be examined; a second light source for illuminating the other eye of the right and left pair of the eyes to be examined; a first cornea position sighting unit having a first checking window and a first cornea position sighting optical system for checking an inter-vertex distance between a cornea peak of the one eye to be examined and a reference position for mounting a lens; a second cornea position sighting unit having a second checking window and a second cornea position sighting optical system for checking an inter-vertex distance between a cornea peak of the other eye to be examined and the reference position for mounting a lens; and a suppression unit for suppressing the irradiation of a light from the second light source from the first checking window through the first cornea position sighting optical system, and suppressing the irradiation of a light from the first light source from the second checking window through the second cornea position sighting optical system.SELECTED DRAWING: Figure 1
【課題】容易に精度よく自覚式検査を行うことができる自覚式検眼装置を提供する。【解決手段】左右の被検眼の内の一方の被検眼を照明する第1光源と、左右の被検眼の内の他方の被検眼を照明する第2光源と、第1確認窓と第1角膜位置照準光学系とを有し、一方の被検眼の角膜頂点とレンズ装用基準位置との頂点間距離を確認するための第1角膜位置照準ユニットと、第2確認窓と第2角膜位置照準光学系とを有し、他方の被検眼の角膜頂点とレンズ装用基準位置との頂点間距離を確認するための第2角膜位置照準ユニットと、第2光源からの光が第1角膜位置照準光学系を介して第1確認窓から照射されることを抑制するとともに、第1光源からの光が第2角膜位置照準光学系を介して第2確認窓から照射されることを抑制する抑制ユニットと、を備える。【選択図】図1 |
