After a lengthy search and extensive testing of several software programs in the area of eye optics and raytracing, we have now gotten as far as obtaining the first reliable values for compensation lenses with the aid of the OSLO program and a skilled OSLO user. OSLO is primarily intended for lens design in the area of industrial optics, i.e. for developing camera and instrument optics. A commercial program from Kidger Optics, USA A beta version of the commercial Visual Optics Lab, Ed Sarver, USA A commercial program called OSLO from Sinclare Optics, USA One of the main reasons why OSLO is the best program from our viewpoint is its capability for using a gradient index lens as a model of the eye lens. This provides a better likeness of the lens of the human eye. We have completed the first calculations using the OSLO program.
Substantial astigmatism is dominant.
Presently, the program is being used to correct the aberrations by means of compensation at various angles to 60 degrees. While this work is under completion, a survey is being written describing the potential usefulness of different raytracing programs in connection with studies of imaging in the eye of rays incident at oblique angles. B. Lens design Lenses are being designed which fulfil the optical compensations prescribed by the OSLO program. As part of a degree project, a student at Lund University has attempted to investigate the optics of pigs' eyes. A number of practical problems have presented themselves, but we believe it will be possible to develop this work further.
