need help with window treatment [View all]

I have a large window in the bedroom and one in the living room. Each is 58" across and 66" down.
face north.
My conundrum is that I want privacy and I want light, and I want it to be easy to go back and forth - between covered windows and uncovered.
I have both windows now, so that during day the upper half is all open and the lower half is curtained, which can be open or closed.
At night I have a shade.
BUT I also have a light outside the window, so I need something darker than the shade so my bedroom can be in darkness.
First I thot about room darkening drapes - but if I pull the drape to the side during day, it will still cut off light in each corner.
if I get a drape on loops, I think it will be hard for me to open and close every morning and night, because I am short. And standing on the ground, not sure I will have enough leverage.

I have considered blinds, but I was reading on another thread here, and reminded me of blinds needing to be dusted - no to that.

I like the looks of this shade.

but I don't know how dark it would be.
But I like the pull, which is easy for me to operate.

Any ideas appreciated
