Apart from pupil dilatation mentioned by another commenter, it also has a lot to do with the reflection created on glass surfaces: if you’re in a room at night and light up a lamp you’ll notice that you can clearly see the reflection of the room on the window, but not what’s outside. This is because the light coming from the lamp, which is reflected by the glass, is much more intense than that coming from outside, which in turn gets suppressed by the former.
The result is that your eye perceives only the reflected light, making it hard to see outside.
