I was hoping for a brighter lens (since I bought them for cosplay) but these did not show up as much as I wanted them to. My eyes are a very dark brown so I expected it. However, they are very pretty in bright light.
If you're looking for a more striking lens, know that these are definitely suited for a more natural look. Even so, they blend beautifully with my eye color! If you're looking for a subtle enhancement and an understated look, these are a very nice addition.
