To be honest, I gave those magnifier glasses a try about a year ago and wasn't impressed at all.
The problem I had was that the lenses have a sweet spot right in the middle, however as the focal lenght is about 5-6 inches, both eyes were not looking through the sweet spot anymore, but just on the inside of it, making the image ever so slightly blurry.
I think part of the problem is that the lenses are plastic.
I returned them to Amazon and spend Eur 63 on an Optivisor DA-5 2.5x Head Band Handsfree Magnifier Visor.
I also bought the Optivisor Optiloupe Additional Clip on Lens and the Optivisor Xenon Clip on Visorlight.
Yes, this is more bulky and expensive, but the increased clarity of the glass lenses is worth every Eur to me.
