PROBLEM TO BE SOLVED: To provide a multifocal lens simulator and a method of simulating a multifocal lens, realizing and undergoing the effect of intraocular lens, a difference between the diffraction type and refraction type, or demerit even when not undergoing insertion operation for a multifocal intraocular lens (before the insertion operation).SOLUTION: This multifocal lens simulator includes: an afocal optical system for emitting light beams entering as substantially parallel light in the form of substantially parallel light beams. A tested lens supporting means for housing a multifocal sample leans having a predetermined basic refractive force and a plurality of refractive forces which are additional refractive force obtained by adding a differential refractive force to the basic refractive force is disposed in front of the afocal optical system. A material to be observed can be observed through the multifocal sample lens and afocal optical system by an observer in the rear of the afocal optical system. The tested lens supporting means is installed at a position optically conjugate with a position at which an eye of an observer is to be placed.COPYRIGHT: (C)2011,JPO&INPIT【課題】多焦点眼内レンズの挿入手術を受けなくても(挿入手術を受ける前に)、その効果、回折型と屈折型の差異、あるいはデメリットを実感・体験できる多焦点レンズシミュレーション装置及びシミュレーション方法を得る。【解決手段】略平行光で入射した光束を略平行光で射出するアフォーカル光学系を有し、該アフォーカル光学系の前方に、所定の基本屈折力と該基本屈折力に差分屈折力を加えた付加屈折力の複数の屈折力を有する多焦点サンプルレンズを収納する被検レンズ支持手段を配置し、上記アフォーカル光学系の後方から観察者が上記多焦点サンプルレンズとアフォーカル光学系を通して被観察物を観察可能であって、上記観察者の眼が配置されると想定された位置と瞳共役関係となる位置に上記被検レンズ支持手段が配置されていることを特徴とする多焦点レンズシミュレーション装置。【選択図】図1
