What can this part do on the mouse?

What's the purpose of this ring around the sensor? Is it a problem if it gets dusty inside?

He can't do anything. This is simply an extra glider so that no dust comes under or against the sensor during use to avoid mouse flicks.

That's for extra glide, if that's dusty you seem to have less glide. dust on the sensor I don't think so well
