STEREOSCOPIC OPTOMETRIC APPARATUS AND GLASSES FOR OPTIOMETRY

摘要

PURPOSE: A stereoscopic optometric device and glasses for vision check is provided to help a user to get an accurate vision check up by providing similar environment with actual user environment. CONSTITUTION: A display unit(110) displays the image for the eyesight examination linearly polarized. A plate phase delay plate(120) is arranged in order to pass light from the display unit. The plate phase delay plate comprises a first area(122) and a second area(124). The first area has a phase delay axis accomplishing the first angle of the light from the display unit to the linear polarization direction. The second part has the phase delay axis accomplishing a second angle of the light from the display unit to the linear polarization direction. C plate phase delay plates are arranged in order to pass the light passing though the plate phase delay plate.
