Not in the way you mean, but I can reduce the (apparent) brightness by holding the hardware further away from my face :-)
When reading most paper books I hold the book quite close in order to see the small type clearly. When I first got my Glo I did the same thing, but then I realised it was much more comfortable to increase the font size and hold it further away. As a result I had to turn up the brightness setting, but that is no problem, the Glo can go brighter that I will ever need.
