Reply to comment by Donebrach in ELI5 why most animals seem have a large number of sensory systems that are close to the brain? by shficjshx

Plus, having sensory organs close to the brain reduces the distance those inputs have to travel. Nervous signals are fast but they do take measure able amounts of time based on how far they must travel. When fractions of a second can mean life and death, getting all the info to your brain quickly means you’re likely to live longer than your butt-eyed peers.

I mean, a study I posted in another comment found that the lag was something like .27 ms/cm of extra distance. So, in the grand scheme of things, it's basically negligible.
