一些立体遮挡观察者无法感知3D刺激的深度，这取决于双眼的视差。这些人没有残疾，占总人口的5%以上。此外，17%-30%的非立体盲年轻人和中青年在某些3D环境中不使用视差信息，这一现象被称为假立体盲。本研究旨在探讨一般人群中假性立体盲比例与老龄化的关系。在一项实验中，134名年龄从17岁到83岁的非立体盲人参与者判断了包含双眼视差和图片深度线索的3D刺激的主观深度。结果表明，青年观察者(17~24岁 )和中青年观察者(25~39岁 )的假性立体盲比例均为29%。然而，在老年人群中，伪立体闭塞观察者的比例增加：中年组(40-54 岁)和高龄组(55-83 岁)的比例分别为65%和82%。这些结果表明，许多人，尤其是老年人群，尽管具有使用视差信息的基本能力，但仍难以从3D图形内容中的双眼视差中感知深度。
Some stereoblind observers do not perceive depth of 3D stimuli that depends on binocular disparity. These individuals, who have no disabilities, comprise over 5% of the general population. In addition, 17–30% of nonstereoblind young and young–middle people do not use disparity information in certain 3D environments, a phenomenon known as pseudo‐stereoblindness. This study aimed to investigate the relationship between aging and the proportion of pseudo‐stereoblindness in the general population. In an experiment, 134 nonstereoblind participants, ranging in age from 17 to 83 years, judged subjective depth of 3D stimuli containing binocular disparity and pictorial depth cues. Results showed that the proportion of pseudo‐stereoblindness among young (17–24 years old) and young–middle aged observers (25–39 years old) was 29%, in both cases. However, the proportion of pseudo‐stereoblind observers increased in older populations: 65% and 82% in the middle (40–54 years old) and senior (55–83 years old) age groups, respectively. These results suggest that a number of people, especially in elderly populations, have trouble perceiving depth from binocular disparity in 3D graphic contents despite their essential ability to use disparity information.
