A method and system for inspecting ophthalmic lenses using absorption where an ophthalmic lens is illuminated with light comprising wavelengths that are substantially absorptive to said lens, the image subsequently detected being created using only light at said absorptive wavelengths. Variations in transmitted light intensity translate into thickness changes in the lens caused by cosmetic flaws. The invention is also directed to imaging lens assemblies employing highly positive-powered field flattening lens elements to image a curved object, such as an ophthalmic lens, onto a flat image plane.

The invention provides correction of wavefront aberrations of the eye that take into account fluctuations in the aberrations due to biophysical rhythms. Correction is provided for an intermediate value of these fluctuations of the wavefront aberrations. This intermediate value is determined by extrapolating a wavefront measurement to predict the overall variation. The final correction is determined using a weighting scheme derived from the clinical comparisons of the frequency and amplitude components of the variations.
