Glare film or solar shades: which should I choose?

Film works all the time and keeps the view clear. Solar shades are adjustable, but the view is filtered when they're down and they need upkeep.

In many spaces, film is enough and the shades become unnecessary. Where you need full darkness at certain times, like a screening room, the two work well together: film handles heat and glare every day, and shades are used only when needed.
