Laura Ponce, a nursery school teacher in Lins, Brazil, suffers from a strange condition that causes her to cry ‘crystal’ tears. The white plaques start off as soft blobs inside her eyes, but they harden when she blinks in an attempt to expel them, finally emerging as solid white crystals.
This happens to her for weeks at a time, with a new plaque forming as soon as she expels another. It gets so bad at times that she has to take time off work, to remove as many as 30 plaque membranes from her eye in a day. “A clot starts to swell then I have to open my eye to take out the membrane,” she explained. “When it dries it hardens, it gets really hard, it hurts a lot.”
