In bright daylight, and at best viewing distances, the bottlenosed
dolphin resolves visual gratings approximately equally wel lin air
and in water. Aerial resolution improves with increased viewing
distance, while underwater resolution improves with decreased viewing
distance. The double-slit pupil overcomes the gross myopia in air
measured by ophthalmoscope and produced the indicated effects of
viewing distance.
