It may seem like there is only so much that we can see with the naked human eye, but new research suggests there's way more to our ocular power than we thought. The study, finds that our color vision gives our eyes the ability to make a distinction between things that differ in thickness by even just a few nanometers. That’s so miniscule, that it’s about the thickness of a cell membrane or even the size of a virus.
“We were able to demonstrate that the unaided human eye is able to determine the thickness of a thin film, materials only a few nanometers thick, by simply observing the color it presents under specific lighting conditions,” said Sandy Peterhänsel of the University of Stuttgart, an author of the study. The researchers conducted various experiments at the University of Eastern Finland, in collaboration with the University of Stuttgart, Germany. They gathered several…
