Scientists have discovered a previously unknown layer lurking in the human eye.
The newfound body part, dubbed Dua's layer, is a skinny but tough
structure measuring just 15 microns thick, where one micron is
one-millionth of a meter and more than 25,000 microns equal an inch. It
sits at the back of the cornea, the sensitive, transparent tissue at the
very front of the human eye that helps to focus incoming light, researchers say.
