General Research

Precise Colour Correction
Spectrally modified coloured filter lenses can correct a timing imbalance in the brain associated with the processing of visual information. The correct colour restores the proper time frame to the processing of visual perception. This reduces distortions and headaches during reading.

Magnetoencephalographic evaluation of Scotopic Sensitivity Syndrome
Synopsis: Subjects with Irlen Syndrome but without Irlen Filters demonstrated a complex field-pattern indicative of multiple generators and fragmented activation of visual areas. With filters, the pattern crystalises into a single dipole that localizes to the parietal-occipital sulcus. In normal subjects, filters disrupt the dipolar pattern.
