Except I've had the issue without ever having been blinded. It happens occasionally when I use a weapon that is a higher level than I am. I can't hit anything for dozens of attacks in a row.
That's also intentional.
Missing from the patch notes was the change that weapons which are a higher level than the player suffer a -20% accuracy penalty for each level they are above the player. That difference does show up on the chance-to-hit percentage, though.
Still, the only way to really notice is to look at your accuracy stat on your stat screen. Something this important really should be in red text on the weapon itself:
-20% chance to hit due to low level.
