Assessing Spatial Vision of Older People

Puntos clave

This research aims to assess the decline in contrast sensitivity and spatial vision in older adults, specifically those over age 60.
Conducted a large-sample study linking contrast sensitivity to visual acuity.
Participants wore optimal optical corrections for testing.
Excluded subjects with significant ocular pathology.
Older adults experience substantial loss of contrast sensitivity at intermediate and high frequencies.
Difficulty in perceiving faces under low contrast conditions was reported.
Findings correlate with expected characteristics of contrast sensitivity functions.

Resumen

ABSTRACT The contrast sensitivity function provides a more comprehensive and sensitive measure of spatial vision than does visual acuity. A large‐sample study of contrast sensitivity during the adult years revealed that observers over age 60 have a substantial loss of sensitivity to intermediate and high frequencies. All observers wore their best possible optical correction for the test distance and were free from significant ocular pathology. We further report that older observers have difficulty perceiving faces under low contrast conditions, which is predictable from the characteristics of their contrast sensitivity functions.
