The title says it and the screenshot shows it all.
The game is unplayable for me in this state, since I can’t really see anything when I try to move around (except the ground).
That will happen if you drink Night Vision Potions during daylight 
Oh … my … gosh …
I am stupid as hell -_-
Didn’t think of that. I did indeed use the Night Vision Potion earlier (much earlier) in the night. Then there were few cutscenes and time moved on. Didn’t think of the fact that the poison might still be effective after such time.
I am going to check it out immediately.
Thank you kindly and sorry for my stupidity 
Edit: Yep, did wait for few hours and the effect from the potion is gone now. Cheers
