What Tears Look Like Under a Microscope

These photos are definitely a lot more beautiful than my face when crying.

From My Modern Met.

Proving that not all tears are alike, Maurice Mikkers showcases their beautiful varieties under a microscope. The Dutch photographer gathered his friends and spent an evening experimenting, asking them to come over and “pick a way they would like to cry.” Participants could choose from cutting onions, eating hot peppers, looking into a fan, or from emotion (like happiness and sadness). Mikkers then captured every shed tear with a micropipet and dispensed them on a slide. The results are a remarkable look at the scientific structure of crying.

There are three basic type of tears—basal, reflex, and psychic. Basal tears keep the eye lubricated, while reflex tears are triggered by irritants such as allergies. Psychic tears, which are perhaps the most well known, relate to profound emotion, like when you cry during a sad film. They’re all composed of ingredients like oils, antibodies, and enzymes that are suspended in salt water.
