Eye Didn't Know!

Testing Your Color Vision

Did you know? There is an online resource which enables you to test your color vision.  The X-Rite company, which manufactures devices which insure color standardization between computer monitors, provides a color test on their website. The test is called the 100-hue test, and involves arranging tiles in order of their hue. It's rather challenging, are you up to it? (the test requires registration). Find the test here.

Did you also know? Except when suspecting optic nerve disease, ophthalmologists rarely test color vision, and rarely so extensively as with the 100 hue test.

Critical Thinking

Brian Dunning is the host of one of my favorite podcasts, called Skeptoid.

Since not everyone listens to podcasts, Brian produced a video which encapsulates what you need to know to think critically. This ability is crucial to evaluating medical and nutritional claims, as well as claims you hear everyday in the media or on the internet.

My blog frequently features possible new treatments for eye diseases. These claims must be evaluated critically. Brian's video is a good place to begin. Especially valuable is his concise description of how a proper clinical trial is designed and implemented.
