Hence, the longer eye provides larger retinal images for both close and distant objects. Two benefits are possible if these mammals had the equivalent of the primate or bird foveae. First, their eyes can be considered to be 2• telescopes. This would suggest that their resolution would be twice as good as the primate eyes. Since experiments suggest that their resolution is not better than ours, we must look for another possible explanation. 1 Intubation of batteleaur eagle in Dr. Stegmann's eye clinic.
The fixating eye, as opposed to a camera on a tripod, is in constant motion. These small movements (called either tremors, drifts, or microsaccades) range in amplitude from seconds to minutes of angular arc. Such movements tend to smear rather than enhance visual resolution. One can only presume that the visual system takes quick, short samples of the retinal image during those smearing movements. 16-18 Knowing the size of the optimal diffraction pattern of a focused point of light allows us to predict the optimal visual acuity for a human eye.
