I think weakening eyesight is my biggest pet peave with getting older. Reading glasses are a pain, especially when laying on your back. I think the poor eyesight also contributes to the "shakes". Could be a lot worse off but seems like extra pair of hands would come in handy.
For soldering/small plastic work I use a small weighted base that has mag glass and alligator clips.
Heres something my 94 yr old Gramma gave me. Big magnifying glass that loops around your neck with a couple spots for adjustments
