Correction of spherical (SA) and longitudinal chromatic aberrations (LCA) significantly improves monocular visual acuity (VA). In this work, the visual effect of SA correction in polychromatic and monochromatic light on binocular visual performance is investigated. A liquid crystal based binocular adaptive optics visual analyzer capable of operating in polychromatic light is employed in this study. Binocular VA improves when SA is corrected and LCA effects are reduced separately and in combination, resulting in the highest value for SA correction in monochromatic light. However, the binocular summation ratio is highest for the baseline condition of uncorrected SA in polychromatic light. Although SA correction in monochromatic light has a greater impact monocularly than binocularly, bilateral correction of both SA and LCA may further improve binocular spatial visual acuity which may support the use of aspheric-achromatic ophthalmic devices, in particular, intraocular lenses (IOLs).
矫正球差（SA）和纵向色差（LCA）可显著提高单眼视力（VA）。在本研究中，我们探究了在多色光和单色光下矫正SA对双眼视觉性能的视觉效果。本研究采用了一种基于液晶的双眼自适应光学视觉分析仪，该分析仪能够在多色光下工作。当分别或联合矫正SA并减少LCA影响时，双眼视力会提高，在单色光下矫正SA时可达到最高值。然而，在多色光下未矫正SA的基线条件下，双眼总和比最高。尽管单色光下矫正SA对单眼的影响大于对双眼的影响，但同时矫正SA和LCA可能会进一步提高双眼空间视力，这可能支持使用非球面消色差眼科设备，特别是人工晶状体（IOL）。
