Accessibility for students with dyslexia/visual processing disorders?

Hello! I’m working with a couple of coding students this term who have some form of dyslexia/visual processing disorder that makes seeing numbers difficult.

So far we’ve tried the OpenDyslexic for Chrome plugin, as well as the OSX Spoken Content feature.

I’m wondering if any others have been in this situation, and possibly found tools/techniques/support to help coders who struggle with these issue? Are there things we in the p5/Processing community could be working on to help?
