通过对比敏感度测试分析8名视力正常的轻度近视受试者（-2 D至-7 D）和8名高度近视受试者（> -7 D）在眼镜和接触透镜矫正下的视觉性能，以确定这些组之间是否存在功能差异。高度近视受试者戴眼镜矫正时，对比敏感度损失具有统计学显著性（p = 0.0382），特别是在较高的空间频率下。然而，在接触透镜矫正的情况下，两组之间的总体差异无统计学显著性（p = 0.5083）。我们认为，这些结果证实了高度近视受试者缺乏任何持续存在的分辨率损失。与眼镜矫正的差异可归因于光学矫正的性质。
The visual performances of eight low myopic subjects (-2 D to -7 D) and eight high myopic subjects (> -7 D) with normal visual acuities were analyzed by contrast sensitivity testing with both spectacle and contact lens corrections to determine if any differences in function exist between those groups. Statistically significant (p = 0.0382) contrast sensitivity losses, particularly at the higher spatial frequencies, were found for the high myopic subjects when corrected with spectacles. However, with contact lens correction, no statistically significant overall difference between the two groups was evident (p = 0.5083). We believe that these results confirm for highly myopic subjects the lack of any consistently present loss of resolution. The differences with spectacle correction are attributable to the nature of the optical correction.
