Why a strip of coloured plastic helps
Many readers with dyslexia keep a coloured overlay strip on the desk. They lay it across the page so that one line sits inside a soft band of colour. The band gives the eyes a place to return to after every blink, glance away, or moment of drifting attention.
On paper, the strip only knows about lines. Sentences, though, are how meaning arrives. A sentence often starts halfway across one line and ends halfway along the next, and that jump is exactly where readers lose their place. Hoverlight follows the sentence instead, wrapping around the line break so the whole thought stays lit.
It works on bold words and links that end a sentence. Lists, quotes and table cells each keep their own sentences. Typing areas are left alone, so it never gets in the way of writing.
Does the colour itself matter? Research on tinted overlays is mixed, and many people simply prefer one shade to another. So pick any colour you like, and turn the strength up or down until it feels right. If a single sentence feels too narrow, turn on Context. The sentences around it light up too, in a softer shade.
