Near vision assessment for adults using the NIH Toolbox.

ABSTRACT:

Introduction

The National Institutes of Health (NIH) Toolbox Near Visual Acuity Test is a novel digitized measure designed to provide an assessment of near vision in a time-and cost-effective manner. This study is the first to report the psychometric properties of the NIH Toolbox Near Visual Acuity Test in a sample of community-dwelling middle-aged and older adults.

Methods

Ninety-eight adults (ages 40-81) completed the tablet-based near vision test and the gold standard chart-based near vision test. Performance on the tablet-and chart-based near vision tests was expressed in logarithmic units. Chart-and tablet-based administration order was counterbalanced. To assess test-retest reliability, the NIH Toolbox Near Visual Acuity Test was administered twice within the same day.
