The Vassen TA204 VIOLET contacts are really great!
On my dark brown eyes, their violet color shows really well, even in natural light. I also love the patern the contacts have, as it makes them look more natural, and gives more depth to the contacts themselves! Moreover, they have a nice diameter. This makes them perfect for cosplay, or even for the doll-eye look. Also, they are super comfortable and do not bother the eyes at all!
In short, they are GREAT contacts! They have an amazing color in both natural light and flash and I am really pleased with them! Highly recommended for people looking for violet lenses :D
