If you live with south facing windows you know what a problem they can be, the sun can make it impossible particularly in the winter to have your blinds open as no matter what you do the sun will come in and cause a problem with glare. This means you either have to deal with the glare or you have to keep your blinds shut every day.  Vertical blinds are the perfect solution for this problem, because you can adjust them throughout the day to keep the glare of the sun out but still allow you to be able to see outside.

We all need to be able to see a bit of natural daylight on a daily basis, but if your windows let too much sun in it can be impossible to deal with. Vertical blinds allow the light in but because of the way they open and close they can keep the worst of the glare out during the day as well.
