I think this akin to roasting yourself. I am not talking about the object that she sells, but have you ever wish to replace your eyes after looking to cursed image?
You've seen unsee juice, now introducing: replacement eyeballs! So you can obtain new eyes that haven't been tarnished by whatever shit you've seen before!
Interesting thing of note. We cannot see her actual eyes after the first image, so it might be safe to assume, since this is Greenteaneko, that she did in fact, tear out her own eyes after seeing that painting.
