How accurate are online vision tests?

ANSWER

You can take these tests on your computer or smartphone. They can examine how well you see, if you have astigmatism, are sensitive to light, or are colorblind. There’s not enough evidence to know how accurate online tests may be compared to an exam in your eye doctor’s office.

You must do the test correctly to get accurate results. And online exams can’t check if you have any eye diseases or the overall health of your eyes. Online tests aren’t designed for people who need strong prescriptions for eyeglasses.
