虽然眼睛的高阶像差会大大降低视网膜图像，但大多数研究只在单眼条件下研究了它们对视力的影响。本文通过构建一个双目自适应光学(AO)视觉模拟器，研究了双目高阶像差矫正对视觉性能和双目总和的影响。双目单色像差的光学矫正显著提高了视力和对比敏感度。然而，这种改善不同于单眼观看所获得的改善。在高空间频率(24c/deg)下，单眼对比敏感度的益处显著大于双眼获得的益处。此外，在受试者本身的高阶像差存在的情况下，较高空间频率的双眼总和最大，当这些像差被纠正时，双眼总和减少。因此，这项研究证明了双眼AO视力测试在了解眼睛光学对习惯性双眼视觉的影响方面的巨大潜力。
Although the ocular higher order aberrations degrade the retinal image substantially, most studies have investigated their effect on vision only under monocular conditions. Here, we have investigated the impact of binocular higher order aberration correction on visual performance and binocular summation by constructing a binocular adaptive optics (AO) vision simulator. Binocular monochromatic aberration correction using AO improved visual acuity and contrast sensitivity significantly. The improvement however, differed from that achieved under monocular viewing. At high spatial frequency (24 c/deg), the monocular benefit in contrast sensitivity was significantly larger than the benefit achieved binocularly. In addition, binocular summation for higher spatial frequencies was the largest in the presence of subject’s native higher order aberrations and was reduced when these aberrations were corrected. This study thus demonstrates the vast potential of binocular AO vision testing in understanding the impact of ocular optics on habitual binocular vision.
