Question

Can the dust or dirt from dirty glasses go into your eye?

Answer 1

Negative.

They can go ONTO your eyes but not INTO your eyes.

This is because there are protective layers that surrounds the whole eye ball (palpabral conjunctival, bulbar conjunctival, cornea, tear film).

Unless you are hit with something small at a high velocity, the protective layers should stop the foreign bodies from entering the eye
