Example of an incomplete blink
This is an incomplete blink. This is annotated as a regular blink, as it substantially occludes the eyeball. This specific example is chosen as it is borderline. If there were less occlusion, I would tend not to record it. If in doubt, a good rule of thumb is to ask yourself whether you would have regarded what you saw as a blink if you did not have the luxery of going back and watching it in slow motion. If the answer is "yes", or even "probably", then it is probably best to record it as a blink.
