It might be your eyes. vergence accomodation conflict. Your brain expect that if you hold something close your eyes automatically focus close, but headset optics make it so everything you see is like 3-10 meters away, so you get bluriness. You might teach your brain not to do that in the headset eventually with more exposure to VR.

Alternatively try closing one eye.
