We sell the FFP and SFP Strike Eagle, and have not seen this, so I would contact Vortex warranty support. They are pretty quick to act.
Keep in mind that you are not going to get the sharpest image at 8X, as this is a budget scope. I would expect some details to be not super-clear, but I would not expect "blurry." IMO, the Strike Eagle is good enough for most 8X shooting.
