And now the long over due final installment of "What's that?" Number 5: The Cerium Intuitive Colorimeter. This one is a bit different to all the other high tech bits of kit (Numbers 1-4 in the series are still available if interested to look back on) in so much as it's not found in many consulting rooms. In short: A box full of coloured lights to help people with certain reading difficulties see the print more clearly. The long answer: An instrument for finding the exact colour and density of tint that will help people with "visual stress" read more clearly and comfortably. The colourimeter allows us to change the "hue" (the colour), the "saturation" (the depth of colour) and the brightness independently to tailor the tint exactly to the patient's needs.
Symptoms of visual stress (sometimes called Meares-Irlen syndrome) can include:
Words appearing to move, blur, or double when reading
Feeling fatigued when focusing on text
Sensitivity to bright light or high-contrast screens
Headaches or eye strain after reading
