Corner of eye

Dora

This is the corner of my 3 month olds eye. It looks like a cut that follows the natural crease of her eye. Any idea of a cause? Anyone else have similar experience? My mind goes immediately to worst case scenario of ocular herpes. PLEASE HELP!

Better pic. It looks like a cut but I'm pretty sure there's no way she could've done that by herself. When she woke up from a nap she had it.
