Assorted Coloured Overlays 10pk

A great alternative to reading rulers, freeing up both hands for writing or typing. Really simple to use, just remove from packaging, place over text and read. Coloured overlays can increase reading speed by 25% or more for people who suffer from visual stress. The overlays have a shiny side and a matt side to provide improved usability over a range of lighting conditions. Reading from the shiny side gives a subjectively crisper appearance to the underlying text, but can reflect overhead lighting. The matt side trades slightly decreased clarity for less reflection. W23.5 x L30.8cm. A4. Pack of 10.
