Combined Method of Objective and Subjective Measurement of Ocular Aberrations

A combined method measuring human eye aberrations is presented in our study, since both objective and subjective method are needed for the measurement of human eye’s wavefront aberration. The optical setup can carry out the two methods in one system, i.e. it can measure the human eye’s wavefront aberration with 4.8-mm artificial pupil when the natural pupil is dilated and then when the subject is watching visual testing chart. The result datum from both objective measurement and subjective measurement is fused on feature level by information fusion method with the weighting factors, which is helpful to combine the advantages of both subjective and objective measurement and emphasize the influence of neural system on human eye. Finally, we have done a series of experiments to demonstrate this combined fusion method and give some discussions.
