In bright daylight, and at best viewing distances, the bottlenosed dolphin resolves visual gratings approximately equally well in air and in water. Aerial resolution improves with increased viewing distance, while underwater resolution improves with decreased viewing distance. The double-slit pipil overcomes the gross myopia in air measured by ophthalmoscope and produces the indicated effects of viewing distance.
在明亮的日光下，以及在最佳观察距离时，宽吻海豚在空气中和水中分辨视觉条纹的能力大致相同。空中分辨率随着观察距离的增加而提高，而水下分辨率随着观察距离的减小而提高。双缝瞳孔克服了用检眼镜测量的空气中的严重近视，并产生了观察距离的指示效果。
