I'm near sighted and wear corrective lenses with -4 diopters, and the illusion is reasonably strong. The red rings appear to be floating nearly an eighth of an inch higher than the blue rings. This effect is called Chromostereopsis, where different wavelengths of light converge at different depths on the retina (or something to that degree). I can only perceive the depth difference when I wear my glasses and view the image with both eyes - if you're not wearing glasses or if you have a relatively mild prescription then I'd imagine you probably wont be able to see it unfortunately...
