Aberrations of the Human Eye across the Horizontal Visual Field

Abstract

Aberrations of the human eyes in the horizontal visual field were measured with modified Hartmann-Shack wave front sensor. The characteristic of third to tenth order Zernike aberration rms both temporally and nasally out to 50° is as follows: considerable differences occur among subjects in the pattern of aberrations, particularly for the dominating second-order aberrations; the third to tenth order Zernike aberrations increase with the visual angle, but the increscent magnitude decreases as the Zernike order increases; in despite of imperfect symmetry, the increscent magnitude is the same on the whole; the third-order Zernike aberrations increases up to 2 times from 0° to ±50° visual angle, the forth-order up to 1.8 times, and the fifth to tenth order up to 1.7~1.3 times.
