The aim of this study is to evaluate the efficacy and safety of a new medical device on the improvement of reading skills of dyslexic patients.

Dyslexia is defined as a specific learning disability that is characterized by reading difficulties, in the absence of intellectual disability, neurological or psychiatric disorder, uncorrected sensory disturbance (sight, hearing) or an educational deficiency.

Dyslexia appears in the child from the earliest stages of learning in the form of a difficulty in mastering the learning of reading. This disorder is manifested by a generally hesitant reading, slowed down, full of errors, requiring a lot of effort for the child and may impact his reading comprehension. The dyslexia-related deficiency is of variable intensity depending on the individual; it may be accompanied by calculus disorders (dyscalculia), oral language (dysphasia), motor coordination (dyspraxia) or attention disorders with or without hyperactivity. In nearly 40% of cases, a child affected by Dys disorders presents several learning disorders.

To date, the causes of dyslexia are not yet clearly established. The wide variety of symptoms and disorders associated with dyslexia does not facilitate the identification of precise neurobiological / psycho cognitive mechanisms. There are therefore several theories: phonological, visual, temporal, cerebellar or proprioceptive auditory processing.

Recently, following work published in 2017, an anatomical cause based on Maxwell's spots could also be a cause of dyslexia.

The aim of this study is to evaluate a new medical device to compensate this probable anatomical cause.

Inclusion Criteria:

• Schooled in CE2, CM1 or CM2,
• French mother tongue,
• For whom developmental dyslexia has been diagnosed by a health professional who specializes in this learning disorder,
• Presenting an IQ ≥ 80 and ≤130 according to the WISC-V test performed by a psychologist,
• For which a written consent was obtained regarding his study participation.

Exclusion Criteria:

• With medical history or presenting a neurological pathology,
• Presenting a developmental disorder (autism, ADHD, ...),
• Presenting hearing disorders,
• Presenting visual disorders,
• Any other condition that, in the opinion of health professionals, could impair its ability to complete the study or could pose a significant risk.
