They should put a blur on the nose. Having it in focus just seems wrong and perhaps distracting from their goal of giving the brain what it expects. Heck, I just tried right now and I'm now old enough that I can't even get my nose into focus at all anymore (pretty sure I could when I was a child, lenses are getting harder to flex I guess).

...based on the position of where it is in your field of view, the digitally rendered nose might not need artificial blur.

When you view it with a head-mounted display, your eyes might just see it as blurry anyway...

The nose would be blurry as the lenses make everything in that area of the screen blurry (at least on the DK2).
