Since I have enough light these days, I'll probably attack this problem from the other end.
There's a thing called a Light Shelf, in which instead of mounting top-to-bottom blinds on a window, you install a shelf a distance below the top of the window, and a blind below it. The shelf is sized and placed so that no direct light gets into the room. Instead the light passing through the window is incident on the top of the shelf, and bounces onto the ceiling. This not only creates more hours of indirect sunlight (nobody ever prioritizes cycling the blinds to optimize for daylight), it also moves more of that light into the center of the room.
I have one window that's a tough size and location for blinds, and the time of day when the light hits me in the face is pretty close to the time when a light shelf would work.
