Study of the dynamic aberrations of the human tear film

Gruppetta, S., Lacombe, F. & Puget, P. (2005). Study of the dynamic aberrations of the human tear film. Optical Express, 13(19), pp. 7631-7636. doi: 10.1364/OPEX.13.007631


The dynamic aberrations introduced by the human tear film are studied by measuring the topography of the tear film surface on 14 subjects using a curvature sensing setup. The RMS wavefront error variation of the data obtained is presented showing the non-negligible contribution of the tear film to overall eye aberrations. The tear film wavefronts are decomposed in their constituent Zernike terms, showing stronger contributions from 4th order terms and terms with vertical symmetry, and the temporal behaviour of these aberrations is analysed.
