Here's a comparison of the 2 most popularly done eyelash extension.

mascara volume is more obvious and gives a thicker eyeliner effect.
Both sets are done in Medium length lashes.
And here are my own current set of lashes, Mascara volume
done with a mixture of Medium and short length lashes.
A close up of my left eye.
