@NicoleCRust My 400 letters were out… Sorry for poor description, no native English here :): Maybe your multifocal lens is different… However, the #diffractiongrating approach is the standard way to create second focus to my knowledge. #optics is not really my field.

@NicoleCRust Well, that with the near and far rings is wrong anyway: #optics The rings form a #diffractiongrating, designed to collect about 50% of the light in the 1st order and the other 50% in zero order (no deflection). The other side of the lens is convex, creating the focus using the first order of the above. So on the _retina_ you have two images superimposed, just like the one on the right in my formerly attached image. If you're looking close, close focus is sharp, distant blurred.
