If you suspect someone may have a problem in the first instance Cerium Overlays are a logical and inexpensive first step towards assessment. This quick and simple screening test uses Cerium Overlays. These overlays are clear coloured plastic sheets that are placed over written work. They work by reducing the perceptual distortions of text. When the overlays are placed over the text many students say 'the words have stopped jumping about'.
Research indicates that a large majority of students read quicker and better using the overlays.
The overlays are available in a wide range of colours and students should try them to see which one is the most comfortable. If after approximately four weeks the student feels the overlay is helping then it would be practicable to have a full test at the opticians using the Intuitive Colorimeter. The Cerium Overlays and Screening Kit can be purchased through Cerium Visual Technologies. Vision and Learning Difficulties by Keith Holland B.Sc. The role of vision problems in children with learning difficulties has varied in popularity over the last twenty years, but has recently come to the fore again with the development of coloured contact lenses for the treatment of dyslexia.
