The exercises

Eight exercises across four conditions

Each condition has a distinct clinical evidence base. The exercises are designed to match — not a single exercise template applied to everything.

Hemianopia & Quadrantanopia

Visual Field Loss

  • Anchor & ScanSaccadic eye movement training into the affected visual field
  • Reading Line ScanVisual scanning practice for reading, rebuilding line-tracking patterns
  • Peripheral FlickerLow-demand peripheral awareness stimulation based on flicker research
  • Visual Search GridSystematic scanning of symbol arrays, building compensatory search strategies
Visual Neglect

Spatial Inattention

  • Smooth PursuitSlow tracking toward the neglected side — the approach with the strongest evidence for neglect recovery
  • Line BisectionSpatial bias calibration that feeds into Smooth Pursuit difficulty
  • Visual Search GridAlso available for neglect, training systematic scanning
Scotoma

Blind Spot Awareness

  • Blind Spot TrackerAwareness training around the blind spot area
  • Gap FillPerceptual completion practice, exercising the brain's ability to interpret incomplete visual information
Why this approach

Condition-specific design

  • Saccadic scanning for hemianopia — grounded in Pambakian et al., Zihl et al.
  • Smooth pursuit for neglect — recommended by German Neurological Society
  • Awareness training for scotoma — not PRL or eccentric viewing
Who it's for

Built for stroke survivors, supported by clinicians

Stroke survivors with visual field loss

Hemianopia, quadrantanopia, or scotoma — all four conditions are supported with condition-specific exercises

Stroke survivors with visual neglect

Spatial inattention exercises using the smooth pursuit approach with the strongest evidence base

Rehabilitation therapists

A structured home practice tool to recommend between clinical sessions, with progress tracking you can review together

Carers and family

A guided, supportive way to practise that doesn't require clinical training

What to expect

Consistent practice, measured progress

Evidence-based protocols suggest 15–30 minutes daily, at least 5 days per week, for 4–6 weeks. Two shorter sessions per day may be more effective than one longer session.

You may notice improvements in how confidently you scan your surroundings, how easily you read, and how aware you are of objects on your affected side.

Stroke Sight is a wellness support tool — not a medical device. It does not diagnose, treat, or cure any medical condition. Always follow the guidance of your neuro-optometrist, stroke rehabilitation team, or other qualified clinician.

Why Stroke Sight

Not a generic brain-training app

General brain-training apps target cognition broadly. They do not address the specific visual and attentional impairments caused by stroke. Stroke Sight's exercises are designed for these conditions, grounded in published rehabilitation research.

07

Progress tracking

View your accuracy and reaction times over time

08

Email progress reports

Share results with your therapist via email — uses your own mail app, no data leaves your device.

09

Works fully offline

No internet connection needed after download. Works on hospital wards, in care homes.

10

Built for changed colour vision after stroke

About 1 in 5 stroke survivors notice their colour vision is different. Three display modes — Standard, High Contrast Yellow, and High Contrast White — let you pick the one that works for your eyes.

Research basis

Grounded in published research

Stroke Sight's exercises are grounded in techniques studied in published clinical research on post-stroke visual rehabilitation.

The SEARCH trial (Rowe et al., 2025) found equivalent benefit from structured practice at home versus face-to-face clinical training — supporting the value of well-designed self-guided tools.

These papers inform the training approach — Stroke Sight is not itself a clinically validated tool.
FAQ

Frequently asked questions

Is Stroke Sight a medical device?

No. Stroke Sight is a wellness support tool designed to complement professional care. It does not diagnose, treat, or cure any condition.

What conditions does it cover?

Stroke Sight covers four post-stroke visual and attentional conditions: hemianopia, quadrantanopia, visual neglect and scotoma.

Does it work for visual neglect?

Yes. The Smooth Pursuit exercise uses slow tracking toward the neglected side with the strongest evidence base for neglect recovery.

Does it work for left and right side?

Yes. When you first open the app, you choose which side is affected. All exercises adapt accordingly.

How long should each session be?

10–15 minutes is ideal. The app recommends exercises based on your energy level — shorter sessions on tired days.

Can my therapist see my progress?

Yes — the app has an email progress report feature that generates a summary you can send to your therapist directly from the app.

Does it need internet?

Only for the initial download. After that, everything works offline — on hospital Wi-Fi, at home, or wherever you practise.

What if I can't see the colours clearly?

Stroke can change how colours are perceived. In Settings › Visual Display you can choose between Standard (green targets, yellow anchors), High Contrast Yellow, or High Contrast White. You can try all three in the free demo before you buy.

Is there a subscription?
