Colorimetry

Scientific research has shown that 'visual stress' can be reduced by colouring the page using spectral filters
 Symptoms of Visual Stress 
  • Movement of print
  • Blurring of print
  • Letters changing size or shape
  • Letters fading or becoming darker
  • Patterns appearing, sometimes described as 'worms' or 'rivers'
  • Illusions of colour-blobs of colour on the page surrounding letters or words
  • Rapid tiring
  • Headache or visual discomfort
  • Sore, red or watery eyes 
Visual stress very often occurs in both dyslexic and non dyslexic individuals.
 
Spectral filters
  • Coloured overlays which can be placed on the page
  • Precision tinted lenses which are worn as spectacles
 
 
 
The colour is specific to each individual and has to be selected with precision. The best colour for use as overlays is unlikely to be the same as that for spectacles. Individuals who find overlays helpful usually derive greater benefit from precision tinted lenses. A full eye examination is followed by an assessment with an instrument called the intuitive colorimeter. This assessment is carried out by a specialist and specifies the optimal tint appropriate for spectacles and contact lenses.The optimal tint can permit a more fluent, efficient and comfortable reading. Some describe this effect as 'magical'.   See Colour Test page for more information.
