If you waited until 48 to get reading glasses, you are lucky & have exceptional eyes. Most people require them at 44 - 45 & is completely normal.
You might want to have them check for cataracts forming. After enduring degraded vision for several years, I had mine removed last summer & my badly degraded vision instantly reverted back to perfect (20/15 where it had been all my life).
My 55" Sony TV at 11' never looked better but I doubt if 4K is going to make a lot of difference at that distance from what I've seen the stores...
