Coslens was kind enough to send me a pair of their rainbow lenses to review! Since I have dark eyes, I wasn't really expecting much but the colour actually shows up quite vibrantly (except the blue section). I wore these contacts for around an hour and they were quite comfortable, however I have yet to try wearing them for longer.
Here are some photos with flash and under natural light! Their prices are super reasonable @ coslens.com 😃
I will post a video on my Instagram so you can see the way light reflects off them~
