If a stroke has taken part of your field of vision, the right daily practice can help you read, move around and notice more of the world again — even though the loss itself may stay.
A stroke can damage the pathways that carry vision to the brain, leaving a person unable to see one side of their field of view. When it affects the same side in both eyes it is called homonymous hemianopia; losing a quarter is quadrantanopia. It is not a problem with the eyes themselves — the eyes work, but part of the picture no longer reaches the brain. Common effects are bumping into things on one side, losing your place when reading, and missing objects or people who approach from the affected side.
Some natural recovery can happen in the first weeks to months. After that, the evidence for directly restoring the lost field is limited and much debated. The approach most stroke guidelines support is different and more reliable: compensation — retraining your eye movements so you actively scan into the blind side and take in more of what is there. You are not getting the field back; you are getting much better at working around it.
People with hemianopia tend to under-explore the affected side without realising it. Compensatory scanning (or saccadic) training builds the habit of making quick, deliberate eye movements toward the blind side, so searching, reading and moving become safer and faster.
Check with your rehabilitation team first — these are general techniques, not a personalised plan.
Before you reach for something or step forward, make a conscious sweep of your eyes toward the affected side. Practise turning it into a habit: “look to the weak side first.”
Losing your place mid-line is common. Put a finger (or a bright marker) at the start of each line on the affected side, and return your eyes to it before moving on. It re-anchors your scan so you don’t skip words.
Lay several objects on a table, or use a page of mixed symbols, and find a specific target as quickly as you can — consciously checking the affected side. Gradually make it harder or busier.
Keeping your head still, move only your eyes in slow, wide arcs from one edge to the other. This trains bigger, more even exploration of the whole scene.
Stroke Sight turns these techniques into guided, levelled exercises with progress you can share with your therapist — and it’s available in 17 languages. There’s a free demo, no account and no download needed.
See Stroke Sight →See a doctor urgently if you notice any sudden new vision change — it can be a sign of stroke. For ongoing hemianopia, ask your GP for referral to a neuro-optometrist, orthoptist or occupational therapist. They can assess whether scanning training, reading strategies or optical aids such as prisms are right for you, and check your suitability to drive.
