Abstract

The accommodation of two groups of six observers each of whom viewed high-contrast checkerboard targets presented at six distances (0.9, 1.8, 3.7, 7.3, 16.6 and 29.3m) against either of two backgrounds (highly textured or textureless) was measured with a laser optometer. Significant differences existed between the accommodative responses at each distance due to backgrounds. Implications for size-distances perception and target detection are discussed.
