Scientists Eliminate Halo Effect from Contact Lenses for Presbyops?

"Since the dawn of the contact lens, wearers with presbyopia have had to endure the notorious 'halo effect'...A corrective method discovered by Israeli scientists may help beat back the blinding nuisances once and for all." That's the word from Digital Trends. "Researchers at Bar-Ilan University in Israel think they have a tenable solution. They describe a technique in the journal Optics Communications that involves a smoothening of the surface of multifocal lenses, a process that 'does not complicate the fabrication complexity of the lens' but 'yields the same optical performance in treating presbyopia and assisting people after cataract surgery,' says Professor Zeev Zavelsky, head of the Electro-Optics study program of the Faculty of Engineering and co-author of the paper."
