My next project will be a eyeglass with a phase plate which have the same aberrations with famous lenses.

I used ur leica 10 years ago and its viewfinder was great. After it I found chance to look from leitz binoculars and they were great also. I prefer to see the world from them.

After these experiences , i investigated simulation of lens aberrations on photographs but it has huge drawbacks.

After reading 7 series patents on eyeglass development , i found that it was possible to manufacture aberrated surface for to correct or simulate aberrations with my super easy lens production technology post.

May be it could be possible also to make filter aberrators and correctors.

sci.optics may help me.

Best ,
