If there's one thing tinkerers like me like to talk about other than the stuff they work on, it's the tools they use. But you'll get different answers from each so I would get the bare minimum then see what you need as you go. But here's my suggestions:
Don't bother with the lamps with magnifiers built in or, in my experience, any of the mounted magnifiers. They need to be too close to the item you're working on and you have no room to work. You will need a light so go for one of these:

And then get yourself a set of reading glasses of different strengths so you can focus on what you are working on. Here's my +2, +3 and +4 pairs:

These are my most used tools for lenses:

The cross head screwdrivers are by Wera. They are Philips types but are JIS compatible which is useful if you work on Japanese stuff. For the Russian stuff you'll need flat bladed screwdrivers mainly but maybe some small allen keys too which I haven't shown.
You'll need lens tissues, this is what I use:

and cleaning fluids:

Rubber grippy things are useful (broken vacuum cleaner belts included):

And you need somewhere to work:

Have fun.
