Thanks, Sebastian, and not stupid.
In my late 40s, just needed to move the screen a little further away.
After that, drugstore reading glasses (buy online for $3 or less/pair). Most recently, three strengths: book, laptop, TV/driving.
Last month I had cataract surgery, so now ($12K later) I need glasses only for very close work.
Update: 'Cataract surgery' means lens replacement.
Be sure to take frequent breaks, and look far -- out a window if possible.
