One time I was exploring our jungle lot and a piece of the forest fought back and whipped a tiny twig at me that just barely grazed my eyeball with the exact amount of caressing needed to knock out my hard contact lens but left me otherwise unaware anything happened.
My vision at the time (I've since had corrective surgery) was so bad that missing one corrective lens was enough to make navigating the lot almost impossible. Mostly because the dense vegetation already limits one view to several feet at best and having that reduced substantially made finding my way out during daytime hours incredibly difficult. If it was nighttime I would have been stumbling even more blindly through it.
I had training at a young age how to navigate through forests with only access to a compass and the sky, and most of the time didn't need a compass. I'm guessing the subject in the story didn't have that. But I can empathize with her having my vision greatly affected.
