What does Spot the Difference train?

It exercises visual attention, scanning patterns and detail recognition — the same skills used to detect changes on the road, in faces, and in printed text.

Is finding differences harder a sign of an eye problem?

Not on its own — many adults find these puzzles tricky. But blurry vision, missing peripheral spots, or trouble seeing one side of the image consistently can suggest a visual issue worth checking with an optometrist.

Can children play this game?

Yes — the puzzles are friendly for older children and great for encouraging visual focus. It is not a substitute for a paediatric eye exam.

When should I book an eye exam?

If you notice persistent eye strain, blurred vision, headaches with screen use, or that one eye consistently misses details, book an exam with Dr. Roxanna Gangi.

Reviewed by Dr. Roxanna Gangi, Optometrist

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.

Frequently asked questions

Want a real, in-person assessment?

Online tools are a great starting point, but a comprehensive eye exam with Dr. Roxanna Gangi can detect conditions that screen-based tests cannot — including glaucoma, diabetic retinopathy, and early macular changes.
