I always read with my glasses on. Sometimes on my Kindle I'll use my reading glasses and a lot of the time on both the Kindle and phone I'll use the reading lense on my bifocals. These aren't graduated, by the way, which could be a problem if they were.
I do pretty much the same thing when watching a video on a tablet. I like old TV shows and I have a 7" Fire with a lot of them on it and I'll usually use my reading glasses or sometimes my bifocals. I can watch a 1 hour show with no problem without a pause. I can't read for an hour without 2 or 3 breaks.
I hold both about the same distance away.
I don't have a TV. I usually watch TV shows on my laptop with Netflix or Amazon Prime or Youtube. None of it bothers my eyes. But I don't think I'm constantly gazing into the screen for extended periods while watching a show like I do when reading.
As for lighting, I've learned to be careful adjusting the lighting when I read or watch TV. I usually use Moon+ on my phone and it's simply a matter of swiping the edge of the screen to make fine adjustments. I generally keep the light as dim as I'm comfortable with.
