# Reading Ruler

A reading ruler is a simple yet effective tool that can help individuals with dyslexia read more efficiently. It is a long and narrow overlay that can be placed over the text, highlighting one line at a time. The ruler can be set to different colors, and the user can choose the one that works best for them.
