Abstract:
A layered blinds device having a series of screens of evenly spaced rods held in parallel relation to one another that allow users to manipulate light penetration and view transparency as independent variables and a method for doing the same. A spacing mechanism adjusts the spacing between the screens which controls the light penetration while an alignment mechanism adjusts the alignment of the rods which controls the view transparency. The blinds can be adjusted manually or by a tracking system.
