I don't think that's what dyslexia is. It's a flaw at a different level of perception, or else people with dyslexia (like myself) wouldn't have difficulty spelling or keeping left right straight. I can read fine, but spelling is hell.

I also think dyslexia is a much wider category with many different root cause than most people talk about. Kinda like how autism exists on a spectrum the same thing is true for dyslexia.
