Abstract:

Measurements of the image forming properties of the eye in white and monochromatic light are discussed. The results show that the eye forms poorer images than an aberration free lens and that its departure from ideal performance increases with pupil size. Since imagery is no better with monochromatic light than with white light, it is concluded that spherical aberration or more properly irregular variation in dioptric power over the pupil is probably the main cause of the departure from ideal performance. The results agree with measurements of visual acuity which show that acuity is not significantly altered by the spectral composition of the stimulus. Experiments with annular as opposed to round pupils are briefly discussed.
