OPTOTYPE PRESENTING APPARATUS

摘要

An optotype presenting apparatus that is capable of carrying out examinations accurately is provided. An optotype presenting apparatus includes a display and a controller. The display includes left eye optotype display regions and right eye optotype display regions. The left eye optotype display regions output light having a first polarization axis. The right eye optotype display regions output light having a second polarization axis orthogonal to the first polarization axis. The left eye optotype display regions and the right eye optotype display regions are alternately arranged along pixel lines. The controller is capable of displaying a plurality of optotypes selectively on the display. Further, the controller controls the display based on a type of an optotype displayed on the display to change display luminance.
