Being very short sighted I remove my glasses and can then get quite close.
I do use goggles though!
I have a small halogen spotlight, you know the dichoric ones they use for
display lighting, small lamp about 2" diam? I place this to one side and
it gives a very good illumination. It also casts a shadow of the drill bit
onto the pcb. Placed so that the shadow is due "east-west" I use this to
give me a fore and aft indication of the drill position.
As the drill comes down I can see the shadow getting closer and closer to
the pad centre and I know I'm right before the drill contacts.
