Dyslexia is the effect of a patient’s visual instability, where letters and words appear to move around and wobble as they are read. This is in part caused by Retinal Ganglion Cells – millions of neurons located within the retina of the eye that receive and collectively transmit visual data to the brain. Patients diagnosed with Dyslexia experience an inhibition of blue light transmitted through these cells, resulting in a vivid overexposure of about 45% red light. Coloured filters have been used to remedy this effect.
The Dyslexic Child defines developmental dyslexia beyond the confines of scientific academia. While the work of Dr. Critchley is pertinent to the understanding of the Dyslexic phenomena, it is the work of an unknown Graphic Designer who conveys the visual dyslexic experience. The fragmentation of the colour red, the blurring of visual data, & the reversal of phonetics, act as a graphical representation of Dyslexia and break the modality of the scientific text. Design has the inherent ability to abstract knowledge and use it to shape our discussion with humanity.
