How to get rid of blur effect on the scene?

Hey there i have a very simple and ugly levels on my project , but the problem is the levels has some Blur effects , if the object is a quite far than it looks very blurish , if a am close to the object they are look fine , but i have to come extremly close to the objects.So how can i fix this issue , note that there is no any Postprocessing volums and effect , simply just lights itself. Here is the pictures of my level and my Engine Scalability Settings , which setting i should change to get rid of Blur effect?
