Accessible eye screening, built on vision science
EyeCheck.app was created by Andy Teo, Developmental Optometrist (FCOVD) at Vision and Perception Practice in Singapore, to bring reliable eye screening to everyone online. Every test is based on the principles of optics and vision science, and draws on over 20 years of clinical practice.
Screening only, not a diagnosis. If a result is outside the normal range, or you’re worried about your vision, book a full eye exam with an eye care professional.
Our story
Can someone live with a cataract and not even know it?
Our founder Andy was born with a cataract in his right eye. Nobody knew until a school vision screening at age 8. EyeCheck.app exists so problems like his are caught early, at home or at school.

About the 17 goals ↗What people say
I wasn’t sure if I needed glasses or not, so I tried this screening tool. It was surprisingly accurate and helped me decide to book a proper eye test after seeing the results. Super convenient and well-designed!
As a primary school teacher, I used EyeCheck to check one of my students who was having trouble seeing the whiteboard. It was quick, easy, and gave me enough confidence to recommend an eye checkup to the parents.
I used this app to check my 4-year-old daughter's eyesight at home, and it was so easy to follow! The visuals kept her engaged, and I felt reassured knowing I could do a quick screening before deciding to visit a clinic.

FAQ
Online eye test FAQ
Can I check my eyes online for free?
Yes. Every test in EyeCheck.app is free and runs in your browser.
Is there a free eye test app I can use on my phone?
EyeCheck works like an eye test app, but it runs in your browser, so there is nothing to download. For accurate results it needs a screen of at least 33 cm (13″), so use a laptop or desktop computer rather than a phone.
How accurate is an online eye test?
An online eye test is a screening tool. It can show signs that your vision may need attention, but the result depends on your screen, lighting and distance, and it cannot examine the health of your eyes. It does not replace a full eye exam.
Can I do an eye checkup online for my child?
Yes. Children from age 3 can take the test using shapes instead of letters, with an adult helping. If the result is outside the normal range, or you have any concerns, see an eye care professional.
How often should I get a full eye exam?
It depends on your age, health and risk factors, so follow your eye care professional’s advice. Many adults are advised to have an exam every one to two years. Book sooner if you notice a change in your vision.
