Measurements of the geometrical aberrations of the eye

Abstract Subjective measurements were made with a telescopic apparatus through small parts of the optical system of the eye. Measures were taken to control the brightness of the object, the state of accommodation and the position of the eye behind the apparatus. The results show that: (1) the focusing system of the eye has an optically inhomogeneous structure; (2) with accommodation, not only a shift of the dioptric power but also an irregular change of the optical structure occurs; and (3) there is at least one state of accommodation for which the homogeneity is better than for the surrounding states of accommodation. This is exactly the state of accommodation for which visual acuity is maximal.
