Well, this one can be a bit tricky so I figured I'd post this video to maybe help out someone that has not found a way to deal with the waves of eyes yet.
This uses 2x 50CC40+ archers and healers, and a 50CC36 valkyrie to act as the main sponge for the final waves. Any units with MR and/or high HP will suffice for this role.
I'm unsure of the exact attack requirements for the archers to be able to 2-shot the eyeballs, but mine in particular can do it (with prince up) and my Soma has 345 base attack before prince buff.
