Large‐Sample Norms for Contrast Sensitivity

Key Points

The main aim is to establish large-sample norms for contrast sensitivity functions among a normal population.
Used a portable microprocessor-controlled instrument for measuring contrast sensitivity.
Measured static and dynamic contrast sensitivity functions of 265 observers.
Conducted repeat measures for six observers after six months to assess measurement consistency.
Median values of contrast sensitivity were reported.
Regions for 75 to 90% of the sample were determined.
Small, nonsystematic differences were noted in repeat measurements.

Abstract

ABSTRACT A portable microprocessor‐controlled instrument automatically measured the static and dynamic contrast sensitivity functions (CSF's) of 265 observers for a normal population at the Dayton Air Fair and Air Force Museum. Repeat measures for six observers taken 6 months later show small, nonsystematic differences from original measurements. Median values of contrast sensitivity as well as regions encompassing 75 of 90% of our sample are shown.
