A4-size transparent overlays, colour matched to the Cerium Coloured Overlays Testing Kit. These overlays are ideal for reading larger texts, sheet music, etc.

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.

NOTE: The colours available in this range of overlays are primarily intended for use by children who have been tested using the Cerium Overlays Testing Kit and may not match similarly named colours from other overlay vendors.
