until Terre Castelnero, who I suspected to be an Irlen client, said she was never able to draw illustrating perspective. An example would be to draw a building showing perspective so that the foreground is larger than the background. I suddenly realized I had always struggled with this issue. Our son, Ryan, who has since been diagnosed with Irlen Syndrome, used to struggle to show an appropriate size of hands of figures he drew. Its all the same to me.
