Oy vey! She looks like an alien Any time I see someone who has naturally dark brown eyes; wear light colored contacts, they look like they have goat's eyes. IMO they look stunning with their own natural color
If someone with hazel eyes leaning toward a light brown wore them, they would look awesome. Or someone wearing silver ones on their grey eyes. But they sound completely useless. And they look uncomfortable, especially on the woman.
I'm betting they're hard lenses that are a little bit thicker than typical to completely encase the diamonds.
