We recently suggested the use of a holographic multivergence target to measure the spherical refractive error and the amplitude of accommodation of the human eye [ K. V. Avudainayagam and C. S. Avudainayagam, Opt. Lett. 28, 123 (2003) ]. In this paper we report the performance of the holographic target in measuring real eyes. The holographic technique compared well with subjective refraction and autorefraction in the measurement of spherical refractive error. The performance of the holographic technique in measuring the amplitude of accommodation was similar to that of the minus lens to blur method and that of the push-up method. These results promote holography as a promising technique for testing human vision.
