A device and method is disclosed for treating macular degeneration, an affliction of the eye. The method includes placing one or more appropriate apertures in said object plane for creating a substantially uniform light distribution, illuminating the or each aperture and measuring the intensity distribution at a plane which is conjugate to the pupil plane in order to calculate the apodization of the projection optics. The assembly may additionally include two or more protrusions extending from an outer perimeter of the arcuate portion for maintaining the persons’ fingers in generally correct alignment. An effort equivalence for each task is determined by normalizing each task work time to the greatest hands-on work time.
