How to take a vision test on your phone

Remember the good old days when a vision test meant awkwardly sitting in a chair, covering one eye, and trying to pick out tiny letters on a wall chart while an eye care professional clucked disapprovingly at your mistakes (no? Just us? Fine)? Well, welcome to the 21st century, where even eye exams have gone digital. Believe it or not, you can now take a vision exam online using nothing but your trusty smartphone.  

What is a vision test on a phone? 

So, what exactly is this magical phone vision test? Essentially, it’s an eye exam on your phone. Various mobile apps now offer vision tests that measure aspects such as visual acuity, color vision, and even astigmatism (that thing that makes lights look like blurry spider webs). 

Overview of phone vision tests 

Phone vision test apps typically guide you through a series of tasks, such as reading letters from different distances or identifying colors, to gauge how well you see. Think of it as playing a game where the prize is knowing whether you need new glasses (winner-winner-chicken dinner). 

Each type of testing app focuses on different aspects of vision. Some apps offer multiple tests in one neat package. This can be a real help for people in a hurry, people without vision insurance, and people who are already staring at their phones all day anyway. 

Technology behind mobile vision tests 

The magic behind these phone vision tests lies in the smart algorithms and fairly complex calibration methods they use. These apps are developed to ensure that the visual stimuli (i.e. tiny letters and colors) will be displayed accurately on your screen. They leverage the phone’s sensors and display settings to provide reliable results.

Accuracy and reliability of phone vision tests 

Hang on a minute... Are these tests the real deal, or just another gimmick like that juice machine you need a smartphone to operate? 

Comparing phone tests to traditional exams 

Phone vision tests are surprisingly accurate, but they're not a substitute for professional exams. The main benefit of phone tests is convenience. They’re great for quick checks and monitoring changes in your vision.  

Scientific validation 

There’s growing evidence supporting the efficacy of phone vision tests. Studies have shown that these tests can be reasonably accurate, with the best tests achieving up to a 95% accuracy. Limitations exist, however, and it’s probably best to see vision exams online as supplemental tools rather than replacements for professional care.
