在横切面和矢状面测定了无核眼的光学成分的厚度和曲率。角膜和晶状体表面比视网膜和脉络膜更接近于球体。角膜、水样和玻璃体的折射率通过两种技术在可见光谱的8个波长处获得。通过浸入白蛋白的晶状体的光束的摄影给了后顶点功率，因此（假设均匀性）等效折射率。基于这一假设，并得到了额外模型的支持，对6只老鼠眼睛的计算显示，色差在光谱范围内为5.8（5.5-6.0）屈光度。纵向色差可能对图像模糊有很大的影响。
Thicknesses and curvatures of the optic components of enucleated eyes were determined in both transverse and sagittal planes. The cornea and lens surfaces are closer approximations to spheres than are the retina and choroid. Refractive indices of the cornea, aqueous and vitreous humors were obtained by 2 techniques at 8 wavelengths across the visible spectrum. Photography of light beams passing through the crystalline lens immersed in albumin gave the back vertex power, and thus (assuming homogeneity) the equivalent refractive index. With this assumption, which is supported by additional modelling, calculations for the eyes of 6 individual rats show chromatic aberration across the spectrum of 5.8 (5.5-6.0) diopter. Longitudinal chromatic aberration may make a signficant contribution to image blur.
