Coloured Overlays can help:

  • Improve print clarity and stability
  • Reduce strain and fatigue
  • Eliminate headaches
  • Improve comprehension
  • Track and keep your place while reading
  • Read faster
  • Read longer and with comfort

Irlen Overlays are the original coloured overlay technology. They are used by hundreds of thousands of students and over one million people worldwide. Irlen Overlays are the only coloured overlays available backed by more than a decade of scientific research and used by more than 4,000 school districts worldwide.

Coloured overlays are most effective for individuals whose difficulties are isolated to reading. If you experience challenges with writing, maths, depth perception, night driving, or the environment, Irlen spectral filters (worn as glasses) will be your best treatment option.
