Self-checks for adults and families
When you want a first signal before deciding whether to follow up
An online color-vision screen works best when you need a low-pressure first pass. It does not replace formal diagnosis, but it is a practical first step before deciding what to do next with family or care providers.

Brightness, glare, color temperature, and device differences can all affect what you see, which is why retesting matters.
A useful self-check should not create panic. It should help you decide whether to retry on another device, talk with family, or book a formal eye exam.

Avoid extreme brightness, strong glare, and warm display filters when possible.
2. Read the explanation before reacting
