Check that link out. I don't know if it's just special effects but it looks pretty realistic to me. If this is "just special effects" then someone should make a video and give themselves reptilian eyes. Someone try to debunk it before saying "this is fake".
I know this is 2 days old but you should search "JustinXSnow" aka Justin Snow, the originator of the video you posted.
He makes creepy music videos so he's proficient with video editing software.

Here is a tutorial on how to make lizard eye video effect, granted it's not as well done as Justin's video but it demonstrates the general idea.
