The four pinhole apertures of the constricted gekko pupil are an adaptation for decreasing the depth of field of the eye, while decreasing the total light flux to the retina. This may be useful for distance estimation at high light levels.
收缩的壁虎瞳孔的四个针孔光圈是一种适应性特征,用于减小眼睛的景深,同时减少进入视网膜的总光通量。这可能有助于在强光水平下进行距离估计。
