Thanks to Keith Miller, an optometrist from New Zealand, for sharing this information on Eye-Search Therapy, a free online service provided by the University College London (UCL) Institute of Neurology.
The service requires registration, and I have not personally tried it yet, though it appears to be very well done and useful. While this applies to general scanning principles, and targets maximizing one’s use of visual search in maximizing residual field function and compensatory strategies, there is a companion program from UCL that targets reading specifically.
