Scientists from the Bar-Ilan University in Israel smoothed the surface structure of a contact lens or an intra-ocular lens to reduce halo effect.

Prof. Zeev Zalevsky, head of the Electro-Optics study program of the Faculty of Engineering at the university, explained that their solution involved smoothening the surface structure of a contact lens or an intra-ocular lens.
“The smoothening does not complicate the fabrication complexity of the lens and yet yields the same optical performance in treating presbyopia and assisting people after cataract surgery, but with about one order of magnitude smaller. This allows people that use such lenses to be able to use them also at night," said Zalevsky.
The study was published in Optics Communication.
