The title is a bit of a cheat really. I have no idea what to do about dyslexia, and I don't think anybody has a universally acceptable solution to the problem. I have included links to two short, but interesting articles that got me thinking about this question.

I sometimes wonder about campaigns like this. Does lighting up some buildings or starting a hashtag campaign really help the people who are suffering? I think in this situation the real difficulty is to find the extra commitment in terms of finance and professionals (teachers, support workers, psychologists) to ensure that resources, training and support are available in our schools.
And this is where campaigns like this really can help. If you are walking down the street, or reading something online, and an image of a building lit up in red makes you think a bit more about how you personally can commit or contribute to supporting those in need, then we are one step closer to finding a real solution.

When I went to school nobody had even heard of dyslexia. But now we have been aware of the problem for almost half a century. How can we accept that so many of our children are going to hate every day they spend in school, without gaining the benefits an education system has to offer? Surely the people who spend all their time working on the national curriculum are clever enough to include alternative and creative pathways through the education system?
