I use plain old stronger strength eyeglasses. Even though I have prescription eyeglasses for some normal activities (computer, driving) I discussed with my eye doc at the time about the need for greater magnification for hand sewing. He said go buy 'drug store' glasses of x strength. At this point I have them in varying strengths scattered through the house for various needs. I do have a halogen table lamp that I also use for hand sewing. It's infinitely adjustable so that, combined with the stronger glasses is the combo that I use. Works well for me and I don't have something strapped to my head or dangling from my neck.
