It's kind of like a one way mirror? One way block the vision and only shows your reflection, the other allows you to see through it?

It sounds fine to me, to be honest; put it up somewhere, anything that goes through one side becomes slower and anything that goes through the other becomes faster. Since you've limited it to one it's not OP, as multiple enemies would be able to flank the user and circumvent it, and it doesn't stop the attacks outright so anyone charging through it will still be able to attack the person.
