Are Vertical blinds the answer for offices?
Yes, Provided that the office seating is such that computer screens are facing away from the window.
Vertical blinds control the light from the left to the right. Because of this the light control is perfect for one computer screen but a problem for the others. If computer screens do face the window, it is advisable to use Venetian blinds. Being horizontal, they diffuse the light upward or downward for everyone therefore negating the problem.
