Online color vision tests – do they really work?

Color Vision Test

Last week we learned (the hard way – blowing through our daily budget in minutes) that maybe we needed to rewrite our Google Web Ads.  After launching the campaign, we noticed that we were getting tons of clicks on our ads for our Color Vision Tests.  We quickly realized that the people who were clicking on our ads were not looking to buy a professional color vision test – they were trying to find a web-based application to test for color blindness.  Weird.

We immediately suspended the offending ad group, but the experience left us with a lingering curiosity as to whether you could really test for color blindness online.  In short, the answer is no.  The huge variation of brightness and color display across different computer and monitor types can make a web-based test only suitable for screening – not diagnosing color blindness.  For an accurate diagnosis of color blindness, it is recommended that a patient get assessed by an optometrist or ophthalmologist under controlled conditions.

Since we are in the business of selling color vision tests, it is good to know that a professional diagnostic tool is still relevant and necessary.  Now we just need to rethink our ads!
