Which lengths are equivalent to 1 μm?
The optical limitations of the eye (such as diffraction by the lens and light scatter by the neural cells in the retina) limits the resolution of the human eye below the theoretical 'pixel limit' of the eye. So to sum up, depending on one's age, one should be able to see targets in the order of 6 - 29 microns.
