An aircraft HUD is usually projected or focused at infinity, so the symbology should look pretty clear unless you are looking at something really close, like less than 10 meters away.

I guess from our POV (pilot in cockpit) eyes are focused on aircraft, not on cockpit and HUD, that's why it is blurry.
