Young Brunette Girl In The Glass Room With Blinds

Varieties
• Persian, or slat
The most common window blinds are slat blinds, which consist of many horizontal slats, usually of metal or vinyl, connected with string in a way that they can be rotated to allow light to pass between the slats, rotated up to about 170 degrees to hide the light, or pulled up so that the entire window is clear. Vertical blinds consist of slats of stiffened fabric, plastic, or metal hanging by one end from a track; like the horizontal versions, the slats can be rotated 90 degrees to allow light to pass through or to fold up on one side of a door or window. Vertical blinds are very good at controlling how much natural or exterior light comes into a room, due to the ability of the slats to close tightly.
