“My brain doesnt connect what im seeing? i constantly forget what i'm doing?”

I honestly have no idea how to describe this. I have perfect 20/20 vision. I can see the texture in the carpet all the way across the room. My family is convinced I have horrible vision, but I don't. My eyes can see fine, but it's like my brain can't register what it is I'm looking at. I hold, phones, tablets, books, even my art projects to where my nose is almost touching it. Not because I can't see it, but because when I hold it away there's this entire world out there I'm not looking at and I cant focus on what I'm doing. This is very frustrating because now I will ruin my eyes doing this but there's not much else I can do. I also have this weird short therm memory issue, where if I'm given a set of three instructions ill do the first and have no idea what the other two are, or ill be setting the table (which I do three times a day every day) I'll put the plates on the table, walk into the kitchen to get silverware and have completely forgotten what I'm doing. then ill fix the drinks, put them on the table and be like "oh! we need silverware." go into the kitchen and get the food. this happens daily with the most trivial things. I'll forget what I'm doing in the middle of a task, like I forget what I'm sewing while I'm sewing it. There's so many other issues I could go on about, but ill leave it there. I was in a car accident as a baby, and have been dealing with these issues for as long as I can remember, so could that have caused this?
