These spiky contacts are used to keep the eyelids of the dead closed
Each culture has a different way of treating funerals. In some places, the dead are burned to ashes or buried directly into the ground. However, some cultures prefer to allow a funeral viewing where people are able to see the deceased person one last time before they’re given a proper burial.
For this kind of event, morticians need to prepare the corpse. They apply some make-up on the deceased person’s face, brush their hair, and put spiky contacts on their eyes. These mysterious objects secure the lids and prevent their automatic opening. To be honest, we were better without knowing this piece of information.
