It is actually my first time to try a different color like this, so the feeling is very new to me, but I like how this lens naturally blends well on to my eyes, I tried taking different pictures/angles under different lights with the lenses on my eyes and sometimes it looks very light most especially when under the sun, but then sometimes I feel like it looks natural on my eyes. But I think it is more suitable for people who do cosplaying. Anyway if you would like to try different things then why not? This lens seems nice and it looks very pretty. It is comfortable to wear and I can say that it doesn't dry my eyes too fast.
