Stroke Sight – Vision Trainer

Ansteyapps Limited

About this app

Wellness support tool — not a medical device.
Stroke Sight is designed to support daily practice alongside professional care. It does not diagnose, treat, or cure any condition. Always follow guidance from your neuro-optometrist, orthoptist or rehabilitation team.
Rebuilding your visual world after stroke, one scan at a time.
Stroke Sight is a visual field training app available as a one-time purchase of £29.99, designed for people recovering from hemianopia, quadrantanopia, visual neglect or scotoma — visual field changes that often follow stroke or acquired brain injury. Guided by established principles of saccade training, smooth pursuit therapy and visual scanning practice, Stroke Sight helps you practise the scanning habits your rehabilitation team is encouraging, anywhere and at any time — no internet connection required.
WHO IS STROKE SIGHT FOR?
Stroke Sight is built for adults recovering from hemianopia, quadrantanopia, visual neglect or scotoma after stroke or acquired brain injury. It complements — not replaces — the guidance of your clinical team.
EIGHT TARGETED EXERCISES — GROUPED BY CONDITION
For hemianopia and quadrantanopia
1. Anchor & Scan — saccade training. Green targets appear across the screen, with 70% on your affected side, and you tap each as quickly as you can.
2. Reading Line Scan — left-anchor reading habit rebuilding. Starting from a red dot in the left margin, scan each line to find bold target words.
3. Peripheral Flicker — peripheral awareness training without moving your eyes. Hold your gaze on the centre

point and detect yellow flickers at the edges of your vision.
4. Visual Search Grid — row-by-row scanning. Find the target star hidden in a grid of symbols, working systematically from left to right.
For visual neglect
5. Smooth Pursuit — smooth pursuit eye-movement training, drawing the gaze across the neglected side with spatial auditory cues.
6. Line Bisection — spatial bias calibration. Mark the midpoint of horizontal lines to recalibrate awareness of the neglected hemifield.
(Visual Search Grid is also used for neglect.)
For scotoma
7. Blind Spot Tracker — awareness training around the blind spot, building a clearer mental map of your scotoma.
8. Gap Fill — perceptual completion practice that supports the brain's ability to fill in around the blind area.
10 ADAPTIVE LEVELS PER EXERCISE
Every exercise has ten difficulty levels with auto-advance. The app starts gently, watches your accuracy and reaction time, and only steps you up when you're ready — so practice grows with you instead of overwhelming you.
