“I never cease to be surprised by the remarkable specificity with which certain individuals choose a colour optimum for the clarity of text. The colour usually remains similar when you re-test these people weeks or months later. If the colour differs from the chosen optimum by a small amount then fluency is adversely affected.”
While a senior researcher at the Medical Research Council Applied Psychology Unit, Professor Wilkins designed the Intuitive Colorimeter, the first calibrated instrument for the prescribing of Precision Tinted Lenses. When a shade is appropriately selected, the lenses can eradicate perceptual distortions commonly experienced by those who suffer from visual stress. The Intuitive Colorimeter is now used by community optometrists world-wide. Professor Wilkins has authored three books and published more than 200 articles in scientific journals.
