Quiz: Whose eyes are these? **UPDATED

So, it seems like Tusya is totally copying some of Makar's old Instagram posts--not only did she post one of herself in an oxygen mask, but now she has also posted a closeup of her eye!  But then again, this is a common practice among the RG girls--especially the blue-eyed ones! See if you can guess who these four eyes belong to! 
I will post the answer in a few days...

**UPDATE**
Here are the answers, from top to bottom:
1) Daria Dmitrieva (wearing contact lenses!)
2) Natalia Bulycheva
3) Alina Makarenko
4) Natalia Pichuzhkina
