Insomnia Genetics

Does eye and eyeball size / shape changes resulting from insomnia? My eyes are much less when I have not slept?

I 'm not sure about this change in my eyes due to recurring insomnia or just due to genetics (when I sleep well my eyes have a tendency to be more like my mother, and when I do not they have a tendency to be less like my father). Sometimes these changes occur independently of sleep. Some tracks?

It's not the shape of the eyeball youe that changes due to lack of sleep, but sometimes the distance between the top and bottom eyelid seems to be narrower when you are exhausted. This is called the palpebral aperture, and it always looks smaller when people are tired that you do not have so much energy to lift the upper eyelid.
