Abstract

In this paper, we propose a diffraction based model to explain how coloured filters are able to improve the reading abilities of readers with abnormal eye saccades. We have explained how light of short wavelengths such as blue forms a broader diffraction image compared to light of long wavelength such as red. It is known that blue filters appear to improve reading ability of dyslexics who often present with abnormal eye saccades. Since blue coloured light gives rise to a diffracted image with is broader, it activates both the centrally located parvocellular ganglions as well as the peripherally located magnocellular ganglions. Thus, both pathways formed by these ganglions are activated even if the saccades are abnormal. In the case of red light, since the diffracted image is narrower, the retinal activation region is also narrow matching the narrow retinal region rich in parvocellular ganglions. Images formed in eyes with abnormal saccades will result multiple crossings of a narrow pencil of the diffracted red light beam across the centrally located parvocellular ganglions resulting in a dramatic rise and fall in neural signal in the parvocellular pathway. This causes image instability resulting in unsteady, unclear and distorted images as seen by some poor readers.
