用一种新的心理物理技术测量了由于单色和色差引起的水平子午线上视网膜的模糊。纵向色差是瞳孔大小为4-5 mm的主要模糊，其次是单色像差，最后是光学横向色差造成的模糊。在一些眼中，由于对称轴偏离瞳孔中心而出现昏迷，但在3只眼中，出现无球差的昏迷。该技术还允许测量相对于几何中心的有效瞳孔中心，并部分分析眼睛参考轴的相对位置。
The blur on the retina in the horizontal meridian due to monochromatic and chromatic aberrations has been measured using a novel psychophysical technique. Longitudinal chromatic aberration gives the dominant blur for pupil size of 4-5 mm, followed by monochromatic aberrations, and blur due to optical transverse chromatic aberration. In some eyes, coma was present as a result of a displacement of the axis of symmetry from the centre of the pupil, but in three eyes, coma was present without spherical aberration. The technique also allows a measurement of the effective pupil centre relative to the geometric centre and a partial analysis of the relative positions of the reference axes of the eye.
