It looks like you're using Inkscape and not using ellipses for the eyes. I find that the extension Ellipse by 5 Points is a great way to do the eyes quickly and correctly (with some clipping). I highly recommend watching the video and trying it out (and familiarizing yourself with clipping if you haven't already). The eyelashes should not be part of the same shape, but should instead be separated into different parts like so . That'll get rid of those weird lines you have there. Hope this helps!
