What is the reading distance simulated by a stereoscopic test instrument?

12 inches
14 inches
16 inches
10 inches

The correct answer is: 14 inches

The reading distance simulated by a stereoscopic test instrument is commonly set at 14 inches. This distance is used because it reflects a typical distance at which individuals read comfortably, allowing for a realistic assessment of binocular vision and depth perception. By simulating this distance, the test can effectively evaluate how well an individual perceives depth and is able to use both eyes together. It ensures that the results are relevant to everyday activities, such as reading and other tasks that require fine visual acuity and coordination. The 14-inch distance is recognized as standard in various visual assessments and reflects both ergonomics and functionality in typical reading scenarios. Other distances like 10, 12, and 16 inches do not align with the common practices for setting the reading distance in such tests, which is why they are not the correct choice in this context.
