From the conclusion of the research paper: "In this work, we have focused on eliminating the spherical aberration, but the optical systems exhibit more aberrations that we have not studied. Nevertheless, we are convinced that this family of freeform lenses has many potential applications."

I don't know much about optics, but the work may not be as incredibly ground-breaking as they make it sound in the news.

"General formula for designing a bi-spherical single element lens"

   Just for spherical aberration corrections ?

  I think we can take this lightly !!.......
