On the weekend I was at a party, and amid all the conversation I began to tell a couple people how you can actually see the blood vessels inside your eyes. And as I spoke, everyone in the room stopped talking at once and listened v-e-r-y closely.
I guess I had forgotten how WEIRD this practice is.
I was able to get a couple people to see it, but I believe this video describes it better than I can.
It’s quite an interesting video. Talks about the blind spots… how our minds fill that information in, and how the eye is configured in such a way as to have our blood vessels be visible. Of course, as I’m sure you’ve noticed, you normally do not see these blood vessels. The answer is the same as why you do not always see your nose, even though it is always in the way.
