What is a color vision test?
A color vision test evaluates how well you can distinguish certain colors and color patterns. One commonly used approach uses colored-dot plates containing numbers or shapes.
PeekVision provides a convenient online screening experience intended to help identify possible difficulty distinguishing certain colors.
How the PeekVision color vision screening works
PeekVision displays a series of color plates in your browser. Each plate contains a visual pattern that may be easier or harder to recognize depending on your color perception.
The test is designed as a preliminary screening tool and does not replace a professionally administered color vision examination.
How to take the test
- Use a well-lit room without strong glare on your screen.
- Set your display brightness to approximately 80–100%.
- Wear your normal glasses or contact lenses if you normally use them.
- Look at each plate for only a few seconds.
- Select the number or pattern you see.
- Complete all displayed plates for the most useful screening result.
What is color blindness?
Color vision deficiency, commonly called color blindness, describes difficulty distinguishing certain colors.
Red-green color vision differences are among the most common forms, although other types of color vision deficiency can also occur.
What is an Ishihara color test?
Ishihara-style testing uses circular plates made of colored dots. Numbers, paths or shapes are embedded within the pattern.
Differences in color perception can make some of these patterns difficult to recognize.
Can an online test diagnose color blindness?
No. An online test can provide useful screening information, but it cannot provide a medical diagnosis.
Results can be influenced by your monitor, phone display, brightness settings, color calibration and room lighting.
If your result suggests difficulty with color recognition, consider discussing it with an optometrist or ophthalmologist.
Frequently asked questions
Can I test my color vision online?
Yes. Browser-based screening can help identify possible color recognition difficulties, although professional testing is more controlled.
Can children take the test?
Children who can understand the instructions and identify the displayed numbers or patterns may be able to complete the screening with adult help.
Can glasses correct color blindness?
Ordinary prescription glasses correct refractive vision problems, not the underlying type of color vision deficiency.
Should I use night mode?
No. Disable night mode, blue-light filters and display color filters while taking a color vision test because they can alter displayed colors.
