The effect of gravity on the amplitude of accommodation.

We measured the amplitude of accommodation in the supine and prone positions of young subjects. We found that gravity does not influence accommodative amplitude. These findings support Schachar's zonular function and accommodative hypotheses that the lens is stable and under tension during accommodation.
