Her glasses go all the way to the side of her face. In bright sunlight like that, and with the photogray feature, there would be a dark lens all the way over to her ear. It goes more like half that distance.
What I see reminds me of my mom’s eyes. She has deep-set Scandinavian eyes which make a shadow, sort of like MW1’s eyes. The sun is shining down on MW1’s arm, so shining down on her right eye similarly - but the right eye is set deeply enough that the bone structure around her eye makes a shadow. It can be seen pretty clearly on the darkened image of MW1 that I’ve got on my blog.
MW2’s eye looks like a high cheekbone creating a shadow on the eye socket because the sun is coming across her face from the left side. Also, if you look at image 12 on my blog, the 70-ish guy’s right eye is in the sunlight, yet the eye socket makes a shadow because it is deeper-set than the rest of the face. The eyebrow and eye socket together make a darker patch on a person’s face in the sun, with or without the eyelids open.
