A clinical trial with 11 subjects was conducted to compare the Armorlite Multiple Drop, the Signet Hyperaspheric, the Sola Hi-Drop, and the American Optical Fulvue types of aspheric aphakic lenses. Reasonable off-axis visual acuities were obtained with the Signet, Sola, and Fulvue types, but poor visual acuities were found with the Armorlite type. Similar visual field limits were found with the armorlite, Signet, and Sola types. Considerably larger limits were found with the Fulvue type than with the other types. However, subjects failed to appreciate these larger limits; this was attributed to the extremely poor image quality near the edge of the visual field with this lens type. Some subjects disliked the poor off-axis image quality with the Armorlite lens type, and it had poor acceptance relative to the other types. Concerning subjective perception of weight, cosmetic appearance, and visual field size, and subjective evaluation of performance of everyday activities, there were no significant differences between lens types. It was concluded that reducing lens off-axis power errors, corresponding to the rotating eye, should remain the most important principle of aphakic spectacle lens design.
一项针对11名受试者的临床试验开展，以比较Armorlite多焦点、Signet非球面、Sola高焦点和美国光学Fulvue型非球面无晶状体眼镜片。使用Signet、Sola和Fulvue型镜片可获得合理的离轴视力，但Armorlite型镜片的视力较差。Armorlite、Signet和Sola型镜片的视野限制相似。Fulvue型镜片的视野限制比其他类型的镜片大得多。然而，受试者并未意识到这些更大的视野限制；这归因于该类型镜片在视野边缘附近的图像质量极差。一些受试者不喜欢Armorlite型镜片离轴图像质量差的情况，与其他类型相比，其接受度较低。关于重量、外观和视野大小的主观感受，以及日常活动表现的主观评估，不同类型镜片之间没有显著差异。得出的结论是，减少与转动眼球相对应的镜片离轴屈光力误差，仍应是非球面无晶状体眼镜片设计的最重要原则。
