I’m Asian so I have naturally dark brown eyes. The gray contacts definitely show up and make my eyes look... sort of silvery blue. I love them! They’re definitely not subtle, but they don’t look outrageously fake either. I will have to say though, the right one doesn’t fit my eye as well as the left so sometimes I see a little blur spot due to the color crossing my pupil. But it’s not impairing my vision in any way and I can drive in them. It’s really like you have something stuck on your eyelash kind of blur.
