We investigated the spectral transmittance of binocular separation glasses for stereotests using the random-dot stereogram technique to know the brightness of the field of view with the glasses. Red–green [TNO stereotest 19th edition (TNO ST)], red–blue [JACO stereo test (JACO ST)], and polarization [Randot Preschool Stereoacuity Test (RPST)] binocular separation glasses were employed. The luminance factor in the red–green binocular separation glasses [TNO ST] was 2.7% and 7.8% on the green and red lenses, respectively, i.e., the red–green binocular separation glasses [TNO ST] had a 2.9 times difference in the luminance factors of the green and red lenses. The luminance factor of the red–blue binocular separation glasses [JACO ST] 16.5% and 13.6% on the blue and red lenses, respectively. The luminance factor of the polarization glasses [RPST] was 38.7% and 39.6% on the right and left lenses, respectively. The red–green binocular separation glasses [TNO ST] had a large difference between the luminance factors of the right and left lenses, which might worsen stereoacuity.

我们使用随机点立体图技术研究了用于立体测试的双目分离眼镜的光谱透射率，以了解眼镜视野的亮度。使用红-绿[TNO stereotest 19th edition (TNO ST)]、红-蓝[JACO stereo test (JACO ST)]和偏振[Randot Preschool Stereoacuity Test (RPST)]双目分离眼镜。红绿双目分离眼镜[TNO ST]在绿色和红色镜片上的亮度因子分别为2.7%和7.8%，即红绿双目分离眼镜[TNO ST]的亮度系数相差2.9倍。绿色和红色镜片的亮度系数。红蓝双目分离眼镜 [JACO ST] 在蓝色和红色镜片上的亮度系数分别为 16.5% 和 13.6%。左右镜片的偏光眼镜 [RPST] 的亮度系数分别为 38.7% 和 39.6%。红绿双目分离眼镜 [TNO ST] 左右镜片的亮度系数差异很大，这可能会恶化立体视度。
