No doubt.

I have noticed as my vision has gotten worse that sometimes I just don't pay attention to what is in front of me. At times it takes a lot of effort to parse out the blurry image so I just let it all meld. In TV shows and movies where I used to study the background sometimes just turn into basically radio plays where I just get the gist of where the characters are, but don't have the energy to pay attention to details.

This has also affected my reading. I am much more likely to search for a Youtube video or other audio explanation of a subject than read it myself - since again reading for long periods takes a lot more concentration when the text is blurry/shifting around.

There is no way to wont lead to mental degradation over time.
