Overview

Laboratory study investigates the association of fixation disparity and viewing distance with near vision fatigue.

Key Points

  • This study aims to explore how fixation disparity and viewing distance relate to near vision fatigue during visual tasks.
  • Young adults with normal binocular vision completed visual tasks for three blocks of 30 minutes.
  • The first block set a viewing distance of 100 cm as a control without near vision loading.
  • The second block used a 50 cm viewing distance to induce near vision load.
  • In the third block, subjects chose their preferred viewing distance.
  • Subjects with longer preferred viewing distances (>63 cm) exhibited steeper fixation disparity slopes with varying distances.
  • The data suggest a weak disparity vergence system, contributing to increased near vision fatigue.
