The skills that you already have are enough to learn photoreading.
Products like EyeQ can probably be a fun way to widen your focus. It would probably help your photoreading skills and at the same time just using photoreading at every opportunity will also improve your photoreading skills so EyeQ could be a detour on the path to improving your Photoreading skills.
If you consider EyeQ as another toy then it could be a fun way to add to your photoreading skills.
If you really want to improve your photoreading skills... Photoread more just for the fun of it
