👉 Blotlessness is a condition characterized by a lack of tears or分泌物，which can be caused by various causes such as dry eyes，sore eyes，dry mouth，or even tears. It's similar to having no tears but it's not always apparent because we don't see them.

👉 Okay, I'm ready to break down the linguistic puzzle that is "blotlessness." Imagine you have a canvas with some random blotting papers on it. These blotting papers are made up of ink and water-based emulsion paints. When you write on this paper, the ink covers the surface like an invisible filter, but when you rub or wipe your fingers over the paper, the ink doesn't peel away.

Now, imagine a blot is a small mark that appears in the ink as if it's stuck to the surface. These blots are so tiny that they can be barely visible from far away. They're like little spots of paint that show up on the canvas when you rub your finger over the paper. But wait! Imagine that the ink doesn't stick to these blot marks, but rather disappears quickly with a faint flash of light. That's why blots are so invisible - they just disappear in the blink of an eye! So, "blotlessness" is kind of like invisibility for ink on a canvas. It's when you don't notice them, and it happens all the time!
