Normative Contrast Sensitivity Functions

Key Points

This research aims to evaluate contrast sensitivity functions in college-age individuals and compare them to existing normative data.
Examined sixty college-age observers with 20/20 acuity using an automated contrast sensitivity system.
Conducted two assessments to determine the presence of a practice effect on contrast sensitivity scores.
Compared obtained scores to published normative contrast sensitivity functions from other researchers.
A significant practice effect was observed, indicating improved scores upon repeated assessments.
Marked differences were found between the present scores and previously published normative data on contrast sensitivity functions.

Abstract

ABSTRACT Sixty college age observers who were pre‐screened for 6/6 (20/20) acuity were examined twice on an automated contrast sensitivity system. A significant practice effect was evident in the obtained contrast sensitivity functions (CSF's). In addition, marked differences were found between the contrast sensitivity scores in the present work and the normative CSF reported by other investigators using similar methods. Implications for the rapid assessment of CSF in applied settings and for the use of published CSF norms are discussed.
