Keywords: cry, tear
There are three types of tears –
-Basal tears – these keep our eyes moist during the day so that they work properly.
-Reflex tears – these happen when you get something in your eyes and your body tries to wash it out.
Psychic tears – when you’re crying. These have a slightly different chemical composition to the other types of tears, including a natural pain-killer hormone!!
