A flat optic lens made of paint whitener — and finer than a human hair — is being hailed by Harvard University researchers as a discovery that could change everything from cell phone cameras to microscopes.

The lens is about two millimeters across and uses a thin layer of transparent quartz that is coated on tiny pillars spanning just tens of nanometers across, MorningTicker.com reports.

A nanometer is one billionth of a meter. A meter is 39.37 inches, just longer than one yard.

The new "metalenses" differ from the curved glass disks currently used in binoculars and cameras, according to researchers.

They allow for the magnification of many nanoscale objects — including those used in sophisticated microchips and in other products where space is a premium, according to the report.

These products also include cameras, virtual reality headsets — even contact lenses, MorningTicker reports.

Nearly all high-performance electronic devices use some nanomaterials, according to the United States National Nanotechnology Initiative.

The images in cell phone cameras, for instance, would be made clearer and sharper because the pillars of the metalenses would interact on a higher level with the light passing through camera lenses, according to researchers.

"This technology is potentially revolutionary because it works in the visible spectrum, which means it has the capacity to replace lenses in all kinds of devices, from microscopes to cameras, to displays and cell phones," Harvard's Federico Capasso told MorningTicker. "In the near future, metalenses will be manufactured on a large scale at a small fraction of the cost of conventional lenses, using the foundries that mass produce microprocessors and memory chips."
