What this Trial Is About
Researchers are evaluating if vision training can improve functional vision in people who have lost part of their visual field due to stroke. The study also aims to understand how vision training affects participants' perception of their visual abilities and their ability to compensate for visual field loss in daily activities, especially related to driving. This trial compares home-based vision training to standard care without training. Participants are assigned to either immediate or delayed vision training groups. The training involves daily 20-minute home exercises using online and manual oculomotor activities, scanning, and visual search tasks over 8 weeks. Weekly phone calls help maintain motivation and provide support. The delayed group starts training 8 weeks after baseline, allowing comparison between immediate and postponed intervention effects. Throughout the study, participants will be assessed at baseline, and at multiple points after training, including 8 weeks and up to 28 weeks depending on the group. Researchers will measure visual field reaction times, reading speed, quality of life, occupational performance, and vision function using specialized tools. Participants are asked to keep a training diary and will be monitored for changes in functional vision and the ability to compensate for visual field loss. Total participation lasts from 20 to 28 weeks.

Weekly telephone follow-up conversations
Duration - 1 day
Participants undergo post-intervention evaluations to assess changes in visual field, reading speed, quality of life, and other vision-related functions.
1 visit (in-person) at 8 weeks after baseline for immediate intervention group; for delayed group, this visit occurs before starting their treatment
