Test Your Eyesight at Home with the EuroEyes Digital Eye Chart

Checking your vision has never been easier. Our online eye test is a simple, interactive version of the classic Snellen chart used in real eye clinics across Europe. We created it to help you quickly understand how your eyesight feels today whether you’re curious about laser eye surgery, monitoring changes in clarity or just wanting a quick check before booking an appointment.

How to use

Stand around arm’s length (about 2 feet) from your screen and read each line from top to bottom. Hover over any letter to see helpful tips! They’ll tell you whether what you’re seeing is normal or whether slight blurring may suggest short-sightedness, long-sightedness or general strain.

Start here – can you see this clearly?
F
Clear? Great.
P
Still sharp?
T
This line is where early blurring can start.
O
Can you still read these clearly?
Z
Slight fuzziness here may suggest nearsightedness.
L
Getting harder? Step closer if needed.
P
Blurry? Might be time for a full test.
E
Still sharp? Great vision!
D
Fading? Book a check-up.

Lower lines test clarity at distance.
E
Can you read this clearly?

Quick guide: what your result may suggest
A simple guide to help you decide whether a professional assessment is worthwhile.
If you noticed… What it could mean Next step
✔️ Top line clear
✔️ Most lines readable
Likely good distance clarity at this moment (in normal conditions) Keep monitoring if you have symptoms (strain, headaches, night glare)
✔️ Top line clear
✖️ Middle lines noticeably blurry
Early refractive changes can start to show here (distance clarity and contrast) Consider a professional eye assessment, especially if driving at night feels harder
✔️ Upper lines clear
✖️ Lower lines difficult even at a comfortable distance
Your distance vision may be under strain or not optimised, even if you “get by” Book an assessment for accurate measurements and tailored advice
✖️ Glare / halos at night
✖️ Squinting, headaches, fatigue
Could relate to dryness, astigmatism, or focus strain rather than “sharpness” alone A full assessment can check tear film, corneal shape and night-vision factors
Note: This guide is not a diagnosis. Lighting, screen brightness, and viewing distance can all affect results.

How to interpret your result

If the larger letters at the top felt clear but clarity reduced as the lines became smaller, this may suggest that your vision is not performing optimally at distance. If you noticed strain, fuzziness or hesitation on the middle lines, this is often where early refractive changes begin to appear.

Struggling on the lower lines does not necessarily mean there is a problem, but it can be a useful signal that a professional eye assessment may be worthwhile, particularly if you experience headaches, eye strain, or difficulty driving at night.

FAQ's

No. This test is a simple screening tool designed to give you an idea of how clearly you can read letters at different sizes. It does not replace a full clinical assessment, which includes diagnostic scans, refraction, eye pressure checks and a full health review by a EuroEyes specialist.

We recommend standing about arm’s length (around 2 feet) from your device. For a more precise feel, view the chart on a laptop or desktop at eye level in good lighting.

Mild blurring can suggest common issues like nearsightedness, farsightedness or astigmatism. It may also happen if your eyes are tired or dry. If blur persists, a comprehensive EuroEyes examination is recommended.

No. Conditions such as cataracts, keratoconus, glaucoma or retinal changes require advanced imaging, the type used in our EuroEyes clinics. This online tool cannot identify medical eye disease.

Try it both with and without your current correction.
• If you see well with your glasses, that’s a good sign.
• If you see poorly even with correction, it may be time to update your prescription or explore alternatives like laser eye surgery, ICL or lens treatment.
