Algorithmic dot plates
Plates are generated from a seed inside the page instead of relying on local image files, which fits the current Cloudflare Workers setup.
Test Center
A crawlable hub for online color vision screening, result interpretation, and scenario guidance
This page is not just the launch point for the test. It also tells search engines and AI search what this screening flow is, who it helps, and how the result should be understood.
Self-checks for adults and families
A calm first-pass path for adults, parents, and guardians who want an initial signal before deciding on follow-up.
School screening guide
Shows how schools can use a screening step before referral decisions or classroom accommodation conversations.
Accessibility review guide
Explains where color-vision screening helps design teams audit interfaces for color-only meaning.
Results guide
Translates result labels into plain-language next steps for retesting, escalation, or follow-up.
Concise result first
You first get a plain-language read on whether the run looks clear, worth retesting, or more suggestive of red-green confusion.
Then decide on the report
The detailed report adds a plate-by-plate review, retest checklist, and reminders before any formal follow-up.
01
Pick the right entry point
Start with the hub, a scenario page, or the results guide depending on your use case.
02
Run the online screening
Complete the plate sequence under reasonably stable screen and lighting conditions.
03
Decide on the next step
Use the result, the scenario guidance, and retest advice to decide whether to escalate into formal follow-up.
Why split this into dedicated pages?
Search engines and AI crawlers understand a one-URL-per-intent structure much better than a single page that tries to explain every use case at once.
Can this replace a formal eye exam?
No. It is best used as a first-pass screen that helps you decide when to retest, how to communicate the result, and when to book a formal eye exam.
Should people read the results guide before the test?
If you are worried about how to interpret the outcome, read the results guide first. If you already know you want the screening flow, go straight to the test.
