Ok it's difficult for me to explain, but let me try to give it with an example.

If I put for example vaseline on my eye lids, after an hour or so I will softly massage the vaseline so it's more well spread out. During this process, a lot of tiny hard skin (?) can be felt, a bit like grains of sand. Anyone knows what I mean?

Reason for asking; I have still not figured out what it is. I think it's some skin or something. However, if I have really a lot of symptoms with my eyes, the vaseline always helps getting rid of it (next day it always leads to increased oil production and moistness of the eyes, I think because of removing the 'grains of sand'). It's reproducible with oil as well.

Just posting it here, cause I never read about it, and I still am not sure what it is, and am kinda curious.
