Ever since the invention of the spectacle lens, which appeared in Europe about 1200 A.D., and the understanding of ocular astigmatism in the 19th century, the correction of refractive errors of the human eye has relied on spherical or toric lenses. Nonetheless it has also been known for a long time that there are other, higher-order, aberrations in the eye that limit the visual performance, especially for larger pupil sizes. Until recently this qualitative knowledge has been more of an academic interest, since it was neither possible to measure nor to correct these aberrations.

However, during the last ten years the research on the optics of the eye has progressed extensively. Measuring techniques that can map the aberrations of the eye have been developed and new ways of correcting the optical errors are being explored. This seminar will give an introduction to the ongoing “quest for supervision”
