    Wait, 0.3mm is huge, you should be able to see that. I don’t think this is right.

      Maybe we do see them, but mistake them for bits of skin or dirt.

      Agreed. 1/64th of an inch is .016". An average human hair is .003" in diameter, that would be as long as five hairs wide. You wouldn’t even need a magnifier to see the largest ones.
