Spot the Difference — Visual Attention Game
10 eye-themed puzzles. Trains visual attention and detail recognition.
What this test measures
Visual attention, scanning patterns, and the ability to detect small differences between two similar images — skills used every day for reading, driving and recognising faces.
Why it matters
Strong visual attention helps you spot hazards quickly, read efficiently, and notice subtle changes in your environment. Trouble doing so on one side may suggest a peripheral vision issue worth checking.
Who may benefit
Anyone who wants a quick visual focus break, plus older children and adults who enjoy lightweight visual training. Dr. Roxanna Gangi can rule out eye-health causes if puzzles feel unusually hard.
Spot the Difference exercises visual attention, scanning patterns, and the detail recognition you use for reading, driving, and recognising faces. Reviewed by Dr. Roxanna Gangi, Optometrist, this free game is a fun screen — not a diagnosis. If puzzles feel unusually hard on one side, book a comprehensive eye exam or explore our other free online eye tests.
