Problems companies tell us about

Wherever people work with color-coded wiring, signal lights, safety signage or quality control, undetected color vision deficiency turns into rework, incidents and liability. Free online tests are fine for awareness - procurement teams themselves call them unacceptable for audits and hiring decisions. Enterprise screening triage is expected to cut occupational-health clinic load by 50-70 %.

We only find out after a mistake happens.

Screen at hiring and periodically, not after an incident. A 3-minute screening before day one costs less than one mislabeled batch.

Our paper plate book is faded and every room has different lighting.

Digital plates are generated fresh for every session and scored on the server. Every candidate gets the same standardized screening.

The auditor asked who was screened and when. We had nothing.

Every screening leaves an immutable audit trail and a PDF report. Who, what, when - ready for internal and external audits.

Inviting candidates on site just for a vision check is expensive.

Send a secure link instead. Candidates screen remotely before the interview, on their own phone, in their own language.

Results live in spreadsheets on a shared drive.

Sensitive results belong in an isolated, access-controlled system with automatic retention and deletion. GDPR by design, not by promise.

Our workforce speaks five different languages.

The candidate interface is multilingual - including Thai, Mandarin, Malay and Hindi. Language stops being a screening barrier.

Understanding color vision

What is color vision screening?

Color vision screening is a quick, standardized way to check whether a person distinguishes colors reliably. The best-known method uses pseudoisochromatic plates - circles of dots where a number is visible only to people with typical color perception. The principle was published by Dr. Shinobu Ishihara in 1917 and remains the worldwide standard for red-green screening.

IshiharaPro brings this principle online. Plates are generated fresh for every session, answers are scored on the server, and the outcome is a clear pass, fail or inconclusive - with a recommendation to see an eye care professional whenever the result is not clear. It is a screening, not a diagnosis: it tells you who should be examined, not what condition they have.

Around 8 % of men and 0.5 % of women live with some form of color vision deficiency. Most compensate so well that neither they nor their employer know - until a task depends on distinguishing a red wire from a green one. That is why structured screening at hiring is becoming standard practice in safety-critical industries.

Who needs color vision screening?

Professional drivers

Traffic lights, brake lights, signage. Driver fitness assessments include color vision in most countries.

Electricians & technicians

Wire color codes are a safety system. Misreading them risks equipment and lives.

Rail & aviation staff

Signals, runway lights and control panels rely on color. Regulators require verified color vision.

Quality control operators

Color grading, display inspection, paint matching - deviations invisible to a deficient eye cost money.

Healthcare & lab staff

Test strips, stained samples and alarm colors carry clinical meaning.

Control room operators

SCADA screens and alarm states are color-coded by convention. Red must never look grey.

Honesty and compliance

IshiharaPro is a screening tool. It is not a diagnosis and we will never claim it is. Diagnosis belongs exclusively to a physician.

That's exactly why you can trust us. Every report carries a clear notice that this is an indicative screening, with a referral recommendation whenever the result is inconclusive.

FAQ

Frequently asked questions

Does this replace a medical examination?

No. IshiharaPro is an indicative screening tool. It shows whether a professional examination is advisable, but diagnosis belongs exclusively to a physician. This notice is on every report.

Is a result from a phone reliable?

For the purpose of indicative screening, yes. Displays vary, which is why we show environment recommendations before the test and score everything server-side. We recommend verifying borderline results with a specialist.

What about GDPR? Results are sensitive data.

Yes, and we treat them that way. Data is isolated per client, every operation is audited and retention is automatic: you set the storage period, the system deletes data once it expires. Candidates give consent before testing.

How fast can I start?

Today. Signup takes a minute and the free tier lets you try a screening with no credit card. You can send your first screening within 5 minutes.

Which languages do candidates test in?

The candidate interface is multilingual including English, Thai, Mandarin, Malay and Hindi, with more languages being added. Administration is available in 14 languages.

What does it cost?

The free tier lets you try one screening a month. Basic is €29/month for driving schools and small sites, Pro is €99/month for clinics and growing companies, and enterprise pricing is individual. No setup fees, cancel anytime.

Can we screen existing employees, not just candidates?

Yes. Many companies screen periodically - for example annually for safety-critical roles, or when an employee moves to a role where color decides. The process is identical: send a link, get a report.
