You can find almost anything on the Internet, including all kinds of sight tests, even on the pages of optician stores.

Testing your vision on the Internet might be fun and easy, but you shouldn’t take the results too seriously.

For example, tests that measure your field of vision must be performed accurately to get reliable results.


Visual acuity tests worked for me

There are plenty of different sight tests available on the Internet. I decided to test them and in addition to visual acuity test, I conducted color vision tests and tests that measure your field of vision.

Visual acuity tests worked well for me, at least when the distance for measuring was correct. You should, however, remember that even if you see all the signs on the test board, it doesn’t necessarily mean that you don’t need glasses in any circumstances. On the contrary, they may help you in some situations.

The problem in visual acuity tests is that if you happen to have incorrect distance when measuring, it might lead you to think that your vision is perfect when the actual situation might be quite different.

Anyhow, these tests are a way to check your vision and to find out if you should have a check conducted by a professional.

Color vision tests were not reliable

I myself have a normal color vision. Despite this fact I didn’t pass all the tests on the Internet on the first try. Later, after I adjusted the clarity and colors of my screen, I managed to pass the tests. All in all, whether you have or have not calibrated your screen makes a big difference on the results.

The color vision tests left me wondering whether some people think that there are problems in their color vision after conducting these tests. On the other hand, some people may think that their color vision is perfect even though it isn’t.

In summary, the sight tests on the Internet are fun, but I wouldn’t draw any conclusions based on the results. Also, remember that if you really want to have your eyes checked, you should always visit an optician or an eye specialist for a professional opinion.

You can find different tests for example here:
