Black Edges 90 degrees

Just recently realized this problem. Is there anyway around this?
The issue is the surface you are looking at, towards the edges thinks it points away from the light because the normal is smoothed and therefore is dark.

I suppose all 90 degree edges should have actual geometric round edges?

That's a normal behavior. Yeah, you can chamfer your 90° degree edges to counter it.

Figured that was about the only solution.
