My wife and I just published a book for kids called Super Color Rangers. It’s written to be a fun read for kids and their parents but can also serve as an introduction to something called Irlen Syndrome. Irlen Syndrome is a perceptual processing disorder caused by the brain’s inability to process specific wavelengths of light. It affects both adults and children.
