Stroke Sight

Four exercises for visual field recovery

Stroke Sight provides structured visual field training designed to encourage eye movements into the affected side. Each exercise targets different aspects of visual rehabilitation:

• Saccadic Search — Find and tap targets that appear in your visual field, training rapid eye movements towards the affected side
• Visual Scanning — Systematically scan a field of items to locate specific targets, building consistent search patterns
• Reading Trainer — Practice tracking lines of text with highlighted targets, supporting return-to-reading confidence
• Free Exploration — Open-ended visual search exercises that adapt to your pace and progress

Key features

• 16 languages — English, Spanish, French, German, Italian, Portuguese, Welsh, Japanese, Korean, Hindi, Arabic, Chinese, Polish, Latin American Spanish, Brazilian Portuguese, and Canadian French
• 10 progressive difficulty levels — Start gently and increase challenge as you improve
• Left and right side support — Exercises adapt to left or right hemianopia
• Progress tracking — View your accuracy and reaction times over time
• Email progress reports — Share results with your therapist via email (no data leaves the device — uses your own mail app)
• Works fully offline — No internet connection needed after download
• No data collected — All progress stays on your device

Research basis

Stroke Sight's exercises are grounded in techniques studied in published clinical research on visual rehabilitation after stroke:

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