This "motion blur" effect was also applied to a certain extent in Skyrim Special Edition and I don't know what others games, the reason or excuse is that the creators or the artistic direction intends to simulate the blur of the eye making what you have right in front of you this well focused and everything else is out of focus. But this is stupid, I CONTROL MY EYE, if I want to focus on something I focus on it myself... I don't need, or want, the game to do it for me. Also the programmers can't know what I'm looking at... they just assume that all the players are going to want to look only at the character in front of them ALL the time, and not get lost in the rest of the environment. It was already limiting that they take away control of the character to stare in one direction without being able to do anything else while listening to the other speak... and now they also want to limit what you can see. At least in Skyrim they leave you with some control or movement of the camera while you're in a conversation, although it's limited control and reduced, and you can cut the dialogue at any time with the press of a single key. Unlike Biomutant. Biomutant could have taken note of how Skyrim have implemented various gameplay mechanics, such as the way characters are written and the ability to have followers, buy a house, and marry.

Ok, in short, there is a mod that totally and forever eliminates that horrible effect, I leave you the link of that mod so you can download it followed by a mod that I also recommend which eliminates the eye patch. Both mods work fine even if you already have a game started:
https://www.nexusmods.com/biomutant/mods/5
https://www.nexusmods.com/biomutant/mods/12
I think you have to register to the page to download the mods, but it's all free, once that's done you just have to click on manual download.

Thank you for the link! I agree with you completely.

I have uploaded to my gallery some screenshots of my character in Biomutant. How about a favor in exchange for a favor? Could you look at these and tell me what you think of him? I spent literally 1 hour in the character creator to see all the race options and try to create the most beautiful body possible, I created him from the Hyla race since it is the one that seemed to me to have the most beautiful legs and they look great when running on all fours (in fact i refuse to take any mount, i run on all fours everywhere, the contrast of the back of the black foot with the sole of the white foot looks great), long snout but very good formed in the lower and upper jaw in addition to not having protruding teeth, head with a good proportion of size with respect to the body, slim but tall body, ears as long as possible, tail as long and fluffy. I'm very happy with the way he looks, for sure he would be among the prettiest guys in Biomutant and with the best genes!

As I told you, I found that mod to remove his eyepatch but I wish I could find one that removes that weird mutation on one of his arms.
I also uploaded 2 images of a friend's creation, he created a character that looks more cute or adorable. Mine looks beautiful but handsome XD

Your character actually looks good, I made mine (if you saw the video you know, Captain Moldears) not attractive and with bad genes on purpose. Why? Because if he wins then he proves that it does not matter where you came from, you can be ugly and clumsy but if you have determination and you are willing to learn you can become much, much more. If this miserable runt was able to defeat the world eaters then anyone can if they don't give up and get up and try again after a defeat. Or I used a random character. One or the other.
