Is It Normal to Have Lingering Black Circles (from Black Eyes) 8 Weeks Post Op? (photo)

It appears that you have dark circles, not bruising. The dark circles are caused by relative hollowness (tear troughs) and shadow phenomenon. You may benefit from filler injections.  See an oculoplastic specialist for evaluation.

In general, swelling after rhinoplasty takes months and months to fully resolve, and bruising can also take several weeks to go away.  You definitely had quite a lot of bruising and so you may find that it takes longer for it to go away.

Yes. It is normal to have some of the blood byproducts that stay behind form a bruise to cause black circles. I would expect this to resolve in time. Be patient. Everything in the plastic surgery world takes time, lots of time. 

Residual hemosiderin deposits from severe swelling in lower lids take months to resolve. I might ry camille tea soaks. 

You certainly got your share of bruising from your original rhinoplasty.  Any darkness from bruising will be temporary.  At this point your best bet is to use some form of camouflage makeup. This is available at most cosmetic stores. A yellow based make up foundation will help cover-up purple.
