looking in at the end of a high fire - at yellow and white hot glazes

Clayarters - here's a question for those that are very picky about when
they end a high-fire glaze firing.

I absolutely love glazing shino and other traditional glazes with over
and underglaze drawings. I even like it when my glazes run, but I want
to control the degree of running, especially in the drawing. Ie. I don't
want the drawing running off the pot, but rather beginning to flow and
merge with the background.

To do this I was wondering what ways there are to look in at the pots at
the end of a high fire, without killing my eyes. I'm used to cleaning up
the atmosphere near my cones with a hairdryer, and having a brief
glimpse through my welder's glass at my pot outlines, but not much else.
I want to be able to see the difference between the shino and the iron
rich over-glaze painting done on the side of a pot.

What sorts of safe techniques are there, to see clearly what is actually
going on?
