What Tears Look Like Under Microscope

People generate tears every day for a variety of reasons, often without even noticing. Whether triggered by onions, allergies, intense emotion or just to keep your eyes from drying out, your body produces a myriad of tears — and they all look completely different from each other.

During a time of personal turmoil, photographer Rose-Lynn Fisherwondered how tears look close up. So she collected 100 tear samples, all taken under different circumstances, and analyzed them under a microscope. And what she discovered was that each tear portrayed a dramatic miniature landscape.

The project, "The Topography of Tears," captures unique moments in human experience. But there's also a scientific reason why every tear looks so different. There are three different types of tears: basal (lubricating), reflex (responding to stimuli) and psychic (triggered by emotion). Each type of tear contains different organic substances, and the molecular makeup depends on the causative agent. For instance, emotional tears contain the neurotransmitter leucine enkephalin, a natural painkiller that the body releases to mitigate stress.

And even tears caused by the same reason might look different once they crystallize. "There are so many variables — there's the chemistry, the viscosity, the setting, the evaporation rate, and the settings of the microscope," Fisher said.

But while the science behind the individuality of tears is fascinating, it is overwhelmed by the poetic power of Fisher's photographs. Each tear is a moment frozen in time, capturing the photographer's physical and mental state forever. "Although the empirical nature of tears is a chemistry of water, proteins, minerals, hormones, antibodies, and enzymes, the topography of tears is a momentary landscape, transient as the fingerprint of someone in a dream. This series ls like an ephemeral atlas," she writes on her website.
