I just buy the cheap narrow reading glasses from the drug store, wear them low on my nose, and look over them when I need distance/middle vision. It probably looks really stupid, but it works and it's really no effort.
The optometrist doesn't even talk to me about bifocal contacts. I haven't heard good things from anyone who's tried them.
ETA: I keep looking at magnifying goggles for close work (in my case, mostly electrical work on the vehicles). They just flip up when you need to look around the room. Here's a much cheaper pair, I don't know the difference. Might be a better option for your soldering. And +1 to SK on nothing but contacts and wrap-around sunglasses on the bici. In fact, when I first started needing vision correction, I had glasses, and needing my peripheral vision for cycling was the whole reason I went to contacts.
