Most likely a film on the eyelens. I use a kleenex tissue rolled and twisted into a pencil shape then torn in half in the middle. The broken fuzzy end is used to apply the solvent (ispropyl in my case) then before that dries I flip the tissue and use the other end to gently wipe and soak up the solution, avoiding residue. I don't use any pressure with either end of the tissue.
Similarly some people use one end of a cotton bud to apply the solvent, then flip it and use the other end to absorb the solution before it dries.
Eyelash/skin oils can be only partially removed and the remainder smeared across the eyelens if the residue isn't soaked up before it dries.
