What brain scans and research tell us about Visual Stress and migraine
Research from fMRI and other brain scans has shown areas of the brain in migraine sufferers with Visual Stress becoming hyperexcitable in response to repetitive stripes. Migraine symptoms can be relieved and this hyperexcitability calmed with precision tinted lenses, individually prescribed using the Intuitive Colorimeter.
Repetitive stripes are rare in the natural world but can be found everywhere in our modern visual environment; striped clothing and soft furnishings, on computer screens and in our built environment. Modern society contains very visually stimulating patterns, for example, escalators, stairs, doors and windows, and most commonly, text when reading.
Reading text is an essential part of life, but for Visual Stress sufferers who are sensitive to repetitive stripes this can be very difficult because of the hyperexcitability it causes in the brain. It is often even harder when the print is backlit, such as on a mobile device, white board or computer screen, as Visual Stress sufferers can be sensitive to light.
