Irlen Overlays are the original colored overlay technology. They are used by hundreds of thousands of students and over one-million people worldwide. Irlen Overlays are the only colored overlays available backed by more than a decade of scientific research and used by more than 4,000 school districts worldwide.
 
Colored overlays are most effective for individuals whose difficulties are isolated to reading. If you experience challenges with writing, math, depth perception, night driving, or the environment, colored filters (worn as glasses) will be your best treatment option.
 
However, colored overlays are an important first step in determining whether the Irlen Method can work for you and provide your first experience with relief.
