I tried one of those lighted magnifiers once. I think it would take me a lot of getting used to.
I'm 56 and notice that scrolling detailed patterns is more of a visual challenge these days. I don't wear glasses or contacts full time (yet), but I wear a pair of reading glasses when scrolling and I have a couple clamp on lights attached to the ceiling joists of my basement shop. I found that aiming the lights from multiple angles helps minimize the blade shadow and works better than the single light I've used for years. One of the lights is an old articulating arm, desk lamp that I salvaged and the other is just a cheap clamp on work light, with the big aluminum reflector. Nothing fancy.
