It is common practice to administer stereopsis tests such as the Randot Stereotest to prospective employees for occupations requiring depth perception. However, there is no evidence that stereoacuity measured with tests such as the Randot Stereotest will predict an individual’s ability to perform a depth perception task at near.
Forty-eight people with normal binocular vision were tested on 2 practical depth perception tests, and their stereoacuity was measured with the Randot Stereotest.
There was little correlation between stereoacuity and either of the practical tasks (r < ±0.1).
These results show that Randot stereoacuity does not reliably predict depth perception ability for people who enjoy normal binocular vision. A better method for determining depth perception ability might be to issue a practical depth perception task.
