Visual Field Trainer

Stroke Sight

Gentle exercises you can do at home to practise scanning and reading after a stroke.

Nine exercises for the four most common post-stroke visual and attentional conditions. Grounded in the saccadic scanning and smooth pursuit training traditions described in published research. The app itself has not been clinically evaluated.

Made for the bigger screen, too

Stroke Sight runs full-screen on iPad and on Android and Amazon Fire tablets. The larger canvas gives more room to see targets and read your progress — the same app, at no extra cost.

The exercises

Nine 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 different problems, but different practice approaches for different needs.

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
  • Scrolling TextReading practice with moving text, training a steady return to the start of each line
  • 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 — an approach widely studied in the neglect rehabilitation literature
  • 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 (not eccentric viewing or PRL training)
  • Gap FillPerceptual completion practice, exercising the brain's ability to interpret incomplete visual information
Why this approach

Condition-specific design

  • Saccadic scanning for hemianopia (also called hemianopsia) — 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 studied in the neglect rehabilitation literature

Occupational therapists and orthoptists

A structured tool for daily home practice between sessions, with progress reports you can review together

Carers and family

Something concrete to support rehabilitation without needing clinical training yourself

What to expect

Consistent practice, measured progress

Many people find a little practice most days easier to keep up than occasional long sessions, and two short sessions can be gentler than one long one. There is no prescribed amount — follow your clinical team's advice on what suits you.

Everyone's starting point and pace are different, and the app makes no promises about outcomes. It keeps a record of the exercises you complete, so you can look back over your practice and share it with your clinical team.

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

Why Stroke Sight

Not a generic brain-training app

General brain-training apps target cognition broadly. They do not address the specific eye-movement patterns that visual field loss and spatial neglect disrupt. Stroke Sight uses different practice approaches for different conditions — saccadic scanning for hemianopia, smooth pursuit for neglect, awareness training for scotoma — each grounded in its own published evidence base. That condition-specific design is what sets it apart.

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 visual rehabilitation after stroke:

The SEARCH trial (Rowe et al., 2025) found equivalent benefit from structured practice regardless of exercise specifics — supporting the value of consistent, daily engagement with any well-designed visual training programme.

These papers inform the training approach — Stroke Sight is not itself a clinically validated tool. It is a wellness support tool designed to complement, not replace, professional rehabilitation.
For families and carers

Buying it for someone you love

Stroke Sight is often bought by a husband, wife, son or daughter rather than by the person who will use it. That works well — it only takes a few minutes to set up on their behalf.

To give it as a gift, the simplest way is to buy the app directly on the person's own phone or tablet, so it stays tied to their account. App Store or Google Play gift cards work too — add credit to their account, then install the app together.

When you set it up, choose their language, then select the condition and the affected side — left or right — as their clinical team has described it. Both can be changed later in the settings.

With the neglect exercises you can take part yourself: sit on the person's affected side during a session and gently encourage them to turn their head towards you. Many families find sessions done together easier to keep up than practising alone.

FAQ

Frequently asked questions

Is Stroke Sight a medical device?

No. Stroke Sight is a wellness support tool designed to complement professional rehabilitation. It does not diagnose, treat, or cure any condition. Always use it alongside guidance from your clinical team. Stop using it if symptoms worsen and speak to your rehabilitation team.

Which conditions does it cover?

Stroke Sight covers four post-stroke visual and attentional conditions: hemianopia, quadrantanopia, visual neglect, and scotoma. When you first open the app, you choose your condition and which side is affected. Exercises then adapt accordingly.

Does it support visual neglect?

Yes. The Smooth Pursuit exercise uses slow tracking toward the neglected side with spatial audio cues — an approach widely studied in the neglect rehabilitation literature. The app itself has not been clinically evaluated.

Does it work for left and right side?

Yes. When you first open the app, you choose which side is affected. All exercises then adapt to present targets in the appropriate direction.

How long should each session be?

There is no set amount. Many people practise a little each day — short sessions are fine, and the app suggests shorter exercises on tired days. Follow your clinical team's advice on what suits you.

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. It uses your device's own mail app, so no data is stored or processed by us.

Does it need an internet connection?

Only for the initial download. After that, everything works offline — on hospital wards, in care homes, or anywhere without connectivity.

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?

No. £29.99 one-time purchase. No subscription, no in-app purchases, no ads.
