Overview

Examination of stereoacuity differences at distance and near in young adults, indicating no significant difference under normal conditions.

Key Points

  • To investigate if there is a difference in stereoacuity when viewing at distance and near using random-dot displays.
  • Compared distance and near stereoacuities using identical formats on a standard and small monitor.
  • Tested twelve young adults with low refractive errors and normal binocular vision.
  • Repeated near-testing with added +2.50 DS lenses and base-in prisms to simulate distance viewing conditions.
  • No significant difference in stereoacuity between distance-habitual and near-habitual viewing for both stereotests.
  • Near-compensated stereoacuity was significantly worse than near-habitual and distance-habitual for both tests.
