Illinois Vision Certification Practice Test

True or False: Mirrors and phorias are built into the stereoscopic vision tester.

1. True

2. False

3. Only for monocular tests

4. Only for distance tests

The correct answer is: False

The assertion that mirrors and phorias are built into the stereoscopic vision tester is false. Stereoscopic vision testing typically focuses on assessing depth perception and binocular vision through the use of specialized tests and equipment that do not necessarily involve mirrors and phoria measures. While mirrors can be used in some types of vision testing to reflect images for assessment, they are not a standard component of stereoscopic vision testers. Additionally, phoria measurements, which evaluate the eye's alignment and its ability to maintain proper focus, are usually done through separate tests rather than being integrated into instruments designed specifically for assessing stereoscopic vision. Therefore, the correct answer accurately reflects the design and function of typical stereoscopic vision testing equipment.
