What is the difference between a "Macro Lens" and "Achromatic Diopters"?

Didn't you already ask this question, and some of the others you recently posted?

I asked these questions a few days ago in one post... but nobody answered, i figured i should re-post them seperately in order to get my answers.

This is all stuff you can google though.

It has to do with focal length and focusing distance. Just google it and read all the stuff on it. Also read how focal length and focal distance affect the image.

I am very aware that I can google all of my questions and find the answers, but I post them anyways in hopes of saving somebody else's time. Isn't that what this forum is for?
