No, blue light glasses are not a dyslexia treatment. Dyslexia is a reading difficulty, and filtering blue light does not address it. That is different from the colored or tinted overlays some people try for visual comfort, which are their own separate thing and not what these glasses do.
What they can do is make screen reading more comfortable by cutting glare and strain, which anyone might appreciate during long sessions. But comfort is not the same as support for dyslexia. For that, consult a specialist who can recommend the right tools and strategies for reading.
