Pukka Pads coloured notepads have been designed with guidance from the Irlen Institute who specialise in products for those with visual perception difficulties. With the use of formulated coloured paper and tinted ruling with margin, the coloured pads can help those with Irlen syndrome and / or Dyslexia. Located within the inside front cover of the pad is a visual stress self-testing form. This will help anyone with Irlen syndrome to assess which colour pad they are most suited to.
