Colorimetry

Visual stress is a photosensitive condition which causes vision problems as well as reading and learning difficulties.

The Intuitive Colorimeter™ was scientifically designed by Professor Arnold Wilkins at the British Medical Research Council in 1993. It allows vision specialists to present colours in a controlled colour space and to accurately identify the precise colour that will resolve the symptoms.

The final chosen colour can be prescribed into Cerium Precision Tinted Lenses. Using modern technology, this can be incorporated into any modern lens design and in combination with anti-reflective coatings and Transitions SGEN 8 technology (sun-adaptive tint).

Johns’ curiosity in the field of the Visual Technologies has allowed him to make an incursion into an area of study related to Visual Stress, a condition also known as Visual Fatigue, Pattern Glare or Meares-Irlen Syndrome. People who suffer Visual stress are susceptible to normal levels of light (from computer screens, mobile devices, office lights, car headlights and outdoors) as well as from repetitive visual patterns found in text & in our surrounds. These can lead to eyestrain, discomfort, headaches and distortion of text whilst reading. In some cases, this may be associated with significant reading difficulties (dyslexia). The effect on the patient varies according to the intensity of the task, the complexity of the patterns and the individual’s susceptibility.
