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

This is my second science-related video, again about the blood vessels in your eye. This time I show you how to see individual white blood cells in your eye.

Is it just me or does this guy sound exactly like Jesse Eisenberg???

[thegnome54]

@bobthebonboncat It's not just you. I've had like a dozen people say this so far! I'm not sure how to feel about it since he's such an ass in The Social Network (which I assume people are referring to). Hopefully I come across as just fast-paced and not cold or aloof!

I think this is male Vi Hart..

[thegnome54]

@mts2457 Thanks, great compliment! I once met Vi Hart at a juggling convention.  True story.

cool videos, I always wondered what these dots were...

[tumandi2705]

can they ever leave my eye

[Xzqx2]

I always thought I was just tripping when I saw this. Thank you!!!!

I always wondered what that was when I looked at the sky! Awesome Zelda poster, by the way.

@thegnome54 Yeah just the timbre of your voice sounds like that guy in the Social Network. But you do not come across as a jerk. Ive learned a lot from your videos, keep posting the cool science!

[papershreds]

@Cb138inRs Perhaps. But @Pascaleiro said he was SIX when he first and last saw them so there's no need in being dramatic and scaring him haha.

[Cb138inRs]

@papershreds @Pascalerio They ARE something to worry about if you have a lot of them quite often.

[MsGreencandy96]

Seeing those, I used to think, "Oh my god, I have supernatural powers and I'm different and unlike normal people O.O"

[papershreds]

@Cb138inRs @Pascaleiro Yep, they're floaters - just cell debris and nothing to worry about :)

[Cb138inRs]

@Pascaleiro Those are called floaters. If you have too many of them, you might have an eye disease.

[Cb138inRs]

You don't sound thaaat much like Jesse at all.
