Age has arrived: bifocals or reading glasses for tying knots while fishing

[MathGeek]

Been noticing this for a couple of years, needing to peek over my glasses or take them off to tie knots. I pre-tie leaders before hitting the water, but invariably the need arises to tie a few knots while on the boat, and I'm running out of time peeking over my glasses.

The fonts on my computer are getting bigger and bigger, but my children's school work and textbook fonts remain the same size, and the range of distances where things are still readable is rapidly shrinking.

So what do you older fellows suggest: bifocals or reading glasses? I am concerned that the limited field of view of bifocals may make knot tying a challenging on a boat bobbing up and down in the waves. On the other hand, switching back and forth between two pairs of glasses might not be optimal either. What do y'all say?
