Coloured Filters

Coloured Filters

Irlen Spectral Filters are lenses precision-tinted for each person. They filter out the exact wavelengths of light which create perceptual difficulties and discomfort. They alleviate problems with the environment, light induced migraine and with the printed page.

Irlen Spectral Filters are the answer for:

  • reading
  • headaches and migraines
  • unresolved concussion headaches
  • depth perception
  • light sensitivity
  • copying from a black/white board
  • maths
  • night driving
  • sports performance

Only a certified Irlen diagnostician can identify the optimal colour-correction hue and saturation.

…significant improvement in reading comprehension and rate for those using Irlen Spectral Filters.
