Further analysis of dry eyes – causes
SPEED OF ONSET
If the onset is very rapid, indication is an auto-immune inflammatory response or bacterial. In my case there was rapid onset, so I suspect auto-immune or bacterial cause.
If onset is slow, then could be related to poor diet/ deficiency/ dropout of mebomian glands/ slowing down of lachrymal glands/ something that is affecting goblet cells (mucin).
EYE PARTS AFFECTED
MUCOUS LAYER goblet cells [almost certainly affected]
WATER LAYER lachrymal glands
OIL LAYER mebomian glands
Can pain be reduced by directly closing off signals from the relevant nerve?
One way to reduce pain would be to take a pain killer for the cranial nerve V (trigeminal). The ophthalmic nerve (V1) carries sensory information from the cornea.
