Magni-clips. They are like clip-on sunglasses that you just, well, clip on your regular glasses. They come in a variety of magnification strengths - They start at 1.00. I think I saw 4.00 but know for sure they go up to 3.00. When you don't want them, they flip up and out of the way and then you just flip them back down when you want them again.
I bought one of the magnifier lights but it was always a battle moving it in and out of the way. I looked at those ones that come with a headband but they just looked so bulky - and I couldn't find any locally to just try before buying. The magni-clips are under $15 and seemed a small risk. I'm really happy with them.
Thought I'd share it with the rest of you. Of course, if you don't wear glasses, they won't work as they'd have nothing to clip to but, if you do, it's another option should you be looking for one.
