Abstract :
We measured the effects of symmetrical spectacle blur on stereo thresholds using anaglyphlc dynamic random element stereograms (ADRES) across a two octave range of hypercyclopean spatial frequencies in three subjects. Symmetrical blur elevated subjects´ stereo thresholds. The absolute and relative amount of threshold elevation increased with hypercyclopean spatial frequency.
