Summary

This trial aims to create a new way of visual training for people with normal vision and those who have vision problems due to stroke. The training method is based on statistical learning theories to make the training easier

Who is the study for?
This trial is for individuals with vision loss due to stroke, including conditions like hemianopia and partial vision loss. It's open to those who have had either ischemic or hemorrhagic strokes that resulted in visual field defects. The study will first involve people without visual impairments before including stroke survivors.
What is being tested?
The trial is testing a new type of visual training based on statistical learning theories. The goal is to improve vision with less training effort. Initially, the method will be tested on people with normal vision, then on those affected by stroke-related visual issues.
What are the potential side effects?
Since this intervention involves non-invasive vision training exercises, no significant side effects are expected. However, participants may experience eye strain or fatigue from the tasks.
