Coloured Overlays

Overlay testing kits for determining which colour of overlay would be most suitable for the child are available. These comprise several sheets of acetate of different colours, which are placed over a page of text. In a straightforward testing procedure, pairs of colours are compared successively, the child being asked to judge which colour makes the text easiest to read. The Wilkins Rate of Reading Test can then be used to measure the amount of improvement in reading efficiency brought about by using the chosen colour.

Overlay testing kits, overlay sheets for regular use, and copies of the Wilkins Rate of Reading Test can be obtained from Crossbow Education Ltd., I.O.O. Sales Ltd or Cerium Visual Technologies (addresses below). The Visual Stress Assessment Pack from Crossbow contains a full battery of testing material and overlays as well as useful information sections on Visual Stress. It is written for ease of use, with clear instructions for conducting individual or whole class assessments. Crossbow Education are a preferred trading partner of Lucid Research, but please note that Lucid has no commercial links with IOO Sales Ltd or Cerium Visual Technologies.
