1. Regular checks are essential. Even if your VA is 6/6, certain eye diseases can develop silently.
2. If your vision isn't perfect, consult an eye care professional for guidance and potential correction.
3. Prevention is better than cure. Don't wait until symptoms worsen—early detection can save your sight.
Are you a 6/6 or 6/12? What do visual acuity test results mean? SNEC optometrists explain.
Understanding visual acuity, test results, and when to seek help
Your eyes are your windows to the world, and keeping them in check is crucial for overall well-being.
But what is visual acuity, how do you interpret the results, and when should you be concerned? Let's break it down in simple terms.
What is visual acuity (VA)?
Visual acuity measures how well you see details at a distance. It's like a scorecard for your eyesight, often compared to the Snellen chart test (shown below) used in clinics.
VA results are recorded in a fraction-like format, such as 6/6 (in meters) or 20/20 (in feet). In Singapore, we use the metric system, so you'll typically see it noted as 6/6.
- 6/6 vision: You can see clearly at 6 meters what a "perfect" eye can see at the same distance.
- 6/12 vision: You see at 6 meters what a perfect eye sees at 12 metres.
- 6/45 vision: You see at 6 meters what a perfect eye sees at 45 metres.
A 6/6 +1 or 6/6 -1 result means you're just above or below the perfect mark, like missing or identifying an extra letter on the chart.

VA and driving requirements in Singapore
Good eyesight is essential for safe driving. In Singapore, here's the VA score you need to drive the following vehicles:
- For personal vehicles (Class 1–3): VA of 6/12 or better in at least one eye.
- For commercial vehicles (taxis, buses etc.): VA of 6/12 or better in both eyes. Additional checks, like color vision and night vision, may also be required.
What if my VA isn't 6/6? Should I be concerned?
Don't worry — it's more common than you think! A lower VA could be due to:
- Uncorrected refractive errors: Maybe your glasses or contact lenses need an update.
- Incorrect use of corrective eyewear: Like wearing the wrong prescription glasses.
- Other eye conditions: Some might not be serious but still need attention.
What to do if your VA is poorer than 6/6
- Visit an optician or optometrist: They can confirm the test results and determine if corrective lenses might help
- .Check for underlying conditions: If glasses don't improve your vision, you might need further testing at a healthcare facility.
- Monitor existing eye conditions: If you already have an eye condition, reduced VA could simply reflect your baseline vision.
Your eyes deserve care and attention, so take charge of your vision health today! For any concerns, book a visit with your optician or optometrist for a comprehensive eye exam.
