close the blinds only to turn on artificial lighting on. Why???! Generally, I don't do this, I like natural lighting when appropriate, but I will do exactly that if the sun is creating glare on the screen I am working with, or if I am facing straight into the sun. Similarly, I would do it if I am dealing with sensitive data.
