It's not about either the particle or the lipid envelope. It's about the water particles containing the viruses. They get emitted when you breathe, and they are several orders of magnitude larger. The virus doesn't float around on its own.

The eyes are less of a problem because you don't breathe through your eyes. Only a limited amount of air contacts them, and no air is emitted from them.

Masks are at least as important for protecting others as for protecting yourself. They filter large volumes of air. Eye protection is useful if you're faced with people breathing directly in your face all day, but they're less important for people who can socially distance.
