Couldn't agree more with Dave (Stavros) etc, about getting your eyes tested and getting glasses, makes a HUGE difference, then get magnifiers.
But hey, they are your eyes, so up to you....
I use both types of magnifiers but, to supplement my glasses.
Our hobby is such that both types of magnifiers will be useful, namely, a stand type and headband.
For me, I use 'extra' illumination which makes for better visibilty, in turn making difficult taskes easier to see and less fatiguing.
To this end, for 'Hobby work', I use 'daylight bulbs'.
