Absolutely! There are two styles. (Maybe even three).
One is a circular florescent light with a magnifying lense in the centre. They are often used by jewellery makers. they are generally on telescoping arms that can be adjusted over the worker's table.
The second is an interesting contraption, presumably made for people who are keen on needlepoint and petitepoint work.
A lanyard hangs around your neck and again, a circular fluorescent light, with a magnifying lens rests on stilts that rest on your chest.
The third is relatively simple. Again, the same electronics attached to a gooseneck, which is inserted in a standpole.
The final one...which really isn't what you're seeking, is similar to a pair of glasses, with illumination lenses at your eyepoint...you end up looking like one of the petshop boys!
Have a look at the below link for an idea:
