Changes in ocular factors transient after watching 3D display, study shows
Medical site helio.com reports that in a study to investigate changes in ocular factors after watching a three-dimensional display, researchers found that alterations were temporary, especially in cases with a large binocular disparity and in older patients.
Yum and colleagues evaluated 38 patients by measuring the near point of accommodation, the near point of convergence and the tear break-up time both before and after watching a 3D display with a 1° or 3° disparity for 30 minutes. The researchers also tested tear osmolarity, tear meniscus height and depth, and conducted surveys of patient symptoms.
