>"an angle" refers to any angle other than the angle directly from the sun.

So do these conceptual glasses have a way to find the direction of the sun, and adjust the moire patterns in real time? Based on the description, it sounded like it would always block rays normal to the plane of the lens, while allowing rays to pass through at any other angle. Rays from the sun will only rarely be normal to the lens, and so they will only rarely be blocked, without an active adjustment to change the "rejection angle." Short of that, I don't follow how the glasses can "tell" sunlight from ambient light, and I don't think it can be done without active logic.

I wasn't talking about the glasses but rather a new window system for homes. But yeah, the windows in my idea would require adjustment based on the time.
