binocular magnifiers

Hello chap
I got an Optivisor set from Micromark with an axtra tilting ( or rather revolving ) extra lens long time ago and am still happy with it. You can find other sources but in all cases take the glass lens even if they are more expensive.

Another option is if you know anyone in the dentistry business. My dad is a dental technician and had an old pair laying around, so see if your local dentist has a pair laying around that he would sell you. the best ones to get are the ones that kind of like a visor, you can flip up the magnifiers when you are not using them and flip down when you need them.

Harbor Freight has a pair that are surprisingly clear optically and they are only $5. http://www.harborfreight.com/cpi/ctaf/Displayitem.taf?itemnumber=37586

They do scratch easy but if you are careful with them they work great although they are not as high-quality as something like the Bausch & Lomb ones.
