Colorimetry & Visual Stress
Colorimetry Assessment
About 40% of dyslexics find coloured lens in spectacles (or Colorimetry overlays) make reading more comfortable; easier and reduce visual stress. Colorimetry has also been shown to help some migraine sufferers.
We use the Intuitive Colorimeter to find the best tint. It replicates the symptoms of visual stress which can include movement of text; letters changing size; moving patterns in the print; words which lift off the page or slope and headaches. It can then be programmed with 100s of different colours to eliminate, or reduce, the symptoms.
The whole Colorimetry assessment experience takes about an hour and a half and is painless. However, it can be tiring especially for small children. Therefore, we recommend 6 years as the minimum age for this procedure and it’s best done with no distractions such as other children, phones etc. in the room.
We can provide coloured overlays. However, these only work on flat pages whereas spectacles with the appropriate coloured lenses work on the whiteboard and PC screen as well. Usually, coloured overlays will have been given in school and while they can be helpful (at first) they’re not very robust so most children stop using them.
We also have several other helpful lenses for visual discomfort made up in trial form. You can try these on to see if you find them helpful, with or without glasses.
