VISION ACUITY: THE PROFESSIONAL VS. THE NON-PROFESSIONAL EXAMINER.
Abstract
In an establishment where acuity screening tests must be given to a large number of entering candidates, it becomes necessary to use non-professional personnel trained specifically to administer acuity tests. In an investigation of the dependability of such non-professional testing, a group of test results for 159 eyes obtained on the one hand by a professional optometrist and on the other by a hospital corpsman were compared and it was found that the non-professional examiner scored forty percent of the acuities the same as the professional examiner, fifty per cent better by at least one line of the test, and ten per cent poorer. There is discussion of possible bases for the difference in this particular test situation. (Author)
