I recommend watching them in order.



Why we have blind spots - and how to see the blood vessels inside your own eye





How to see white blood cells in your eye - the Blue Field Entoptic Phenomenon

First one didn't work for me, second one did. Pretty cool.

[Ratt]

Cool. They both worked for me.

[Geor!]

That's awesome, dude!

Pretty good videos. And he made a good but subtle point. A lot of people generalize blue field entoptic phenomenon as being visual snow. Not the same in origin. You get to experience a bit of that tunnel vision he spoke of during a visual field test. Because of staring at the center of a bright white background while trying to hit a button everytime you see a tiny little spec pop up somewhere in the pattern. This over a period of 10-15 minutes causes quite a headache.

I half assed it and it was cool as fuck. Now for the index card version.

Thanks for posting those. I kind of knew the first one but the second one I've experienced many times and never knew why. Flying and staring out the windows is a great way to experience the second one.
