Vision Blinds :
Vision Blinds by Orion Blinds are the best solution for an area where you want flexibility. This blind replaces the clunky roller blind that has a Sunscreen (see through) drop and a Block out drop. Instead you will have a slimline headbox that can be installed in the reveal or on the face of the Architrave. There is a simple single chain to operate.
You can roll it completely away, Have the fabric at half, allowing you to look out but shielding you from prying eyes. Or you can adjust the blind to the block out mode simply by using the cord. I love these blinds as a kitchen blind as it is easy to clean with a warm soapy sponge.
