Optical quality in barn owl eyes is presented in terms of measuring the ocular wavefront aberrations with a standard Tscherning-type wavefront aberrometer under natural viewing conditions. While accommodative state was uncontrolled, all eyes were focused within 0.4D with respect to the plane of the aberrometer. Total RMS wavefront error was between 0.06 and 0.15 microm (mean: 0.10 microm, STD: 0.03 microm, defocus cancelled) for a 6 mm pupil. The results suggest that image quality in barn owl eyes is excellent.
仓鸮眼睛的光学质量是通过在自然观察条件下使用标准的策尔宁型波前像差仪测量眼波前像差来呈现的。虽然调节状态未受控制，但所有眼睛相对于像差仪平面的聚焦在0.4D以内。对于6毫米的瞳孔，总均方根波前误差在0.06至0.15微米之间（平均值：0.10微米，标准差：0.03微米，散焦已消除）。结果表明仓鸮眼睛的图像质量极佳。
