Colour Vision Screening

Before you begin

1. You get 15 seconds for each plate — 25 plates in all.
2. Tap the number you see. Once chosen, an answer can't be changed .
3. If the timer runs out, that plate is counted as missed .
4. View on a bright screen with night-mode off for a fair result.
5. This is a screening indicator, not a medical test .

Important: Screen colours vary by device, so this can't replace the calibrated Ishihara plates used at the DG Shipping medical. Use it only as an early heads-up — never as proof of fitness or a reason to worry. Final colour-vision fitness is decided only by a DG Shipping-approved doctor.

About this screening: It uses original, computer-generated Ishihara-style plates as a convenience indicator only. It is not a medical examination and its result — pass or otherwise — has no official standing. Colour-vision standards for Merchant Navy are set by DG Shipping and assessed only by an approved doctor on calibrated plates. Don't self-diagnose from this screen either way; if in doubt, get a professional eye test. HBIMS-NAF&SA is an admissions facilitation framework , not an MTI, and offers no fitness or admission assurance.
