Tears can look different under a microscope depending on their emotional or physiological origin. This idea was popularized by photographer Rose-Lynn Fisher in her project The Topography of Tears, where she used a microscope to photograph the crystallized salt patterns of different kinds of tears. What she found was that tears triggered by emotion (like grief or joy) appeared different in structure from those caused by irritants (like chopping onions) or reflex tears (like those that flush out dust or wind).
Here's a general breakdown:
Basal tears (the kind that keep your eyes lubricated) have a relatively uniform appearance.
Reflex tears (from irritants like smoke or onion) are more watery and contain fewer proteins.
Emotional tears tend to have more complex and varied patterns, possibly due to the different hormones and proteins they contain, such as stress hormones like cortisol.
