DaveS,

When I was an amateur astronomer we used a similar technique called “averted vision”. The explanation given was that the rods and cones off centre in the eye were more sensitive than those that typically receive more light.

I’m pretty amazed at all the wonder and skepticism on this thing. I learned about the blind spot in elementary school. I mean, you can do the same thing with two fingers, making one fingernail disappear, almost anywhere. Like the demonstration in the video, if you vanish a fingernail, then move that finger upward until the nail emerges from the top of the dead zone, your whole finger appears, not a finger with a hole. It’s fun to play with, and has been since grammar school.

There’s another thing I’ve always noticed. If I’m looking at a star or planet, I can actually see it much better if I look JUST off to the side of it. I wonder if it has something to do with my blind spot. (No, I don’t have cataracts.)

Why doesn’t it work for me?
Could it that I am
I am Left handed and Right eye dominant?

Worked for me and I’m right hand / left eye dominant. If people don’t have a way to reverse this video and don’t have vision in their left eye why not just do exactly the same thing with their right eye but to a point off the left side of their monitor? There isn’t anything magical about looking at the ‘x’ in the video it is just that the guy’s head has to be in your blind spot.

Andy C. — if you download the video, maybe there’s a way to reverse the image.
