An article in the most recent (March-April) issue of American Scientist includes an article on "why different people see different things." I haven't digested the article as yet, but one of the illustrations shows an experimental setup in which the test subject sees one view with one eye through a blue filter and a different view with the other eye through a red filter. A caption suggests that a red filter reduces the "eye dominance" effect if it's the subdominant eye that's looking through the red, but has little effect if it's the dominant eye looking at the red view.

This might suggest that a red lens on both eyes would reduce the "dominance" of the stronger eye, but whether that would aid or aggravate the situation for dyslexics (or for anyone else) is sort of an open quetion that the article probably doesn't explore.

It appears that the article as a whole does support the notion that "red spectacles" could make you think differently since you do quite literally "see different things" to think about.
