即使用最好的眼镜或隐形眼镜矫正，正常人的眼睛仍然。当瞳孔很大时，会出现单色像差而使视力模糊。我们已经成功地纠正了这些像差使用自适应光学，提供正常的眼睛与超常的光学质量。当观察者通过自适应光学观察刺激时，对精细空间图案的对比敏感度增加。眼睛的像差也限制了视网膜图像的分辨率，这是自检眼镜发明以来就存在的限制。我们已经构建了一个眼底相机配备了自适应光学，提供前所未有的分辨率，允许成像的微观结构的单细胞大小的活人类视网膜。(C)1997年，美国光学学会。
Even when corrected with the best spectacles or contact lenses, normal human eyes still. suffer from monochromatic aberrations that blur vision when the pupil is large. We have successfully corrected these aberrations using adaptive optics, providing normal eyes with supernormal optical quality. Contrast sensitivity to fine spatial patterns was increased when observers viewed stimuli through adaptive optics. The eye's aberrations also limit the resolution of images of the retina, a limit that has existed since the invention of the ophthalmoscope. We have constructed a fundus camera equipped with adaptive optics that provides unprecedented resolution, allowing the imaging of microscopic structures the size of single cells in the living human retina.
