These are the most comfortable contacts I've ever worn. They dont seem to slide around too much and I honestly cant feel them AT all. Which isnt common in my experience with non prescription contacts. My issue is that they look NOTHING like the picture. They barely change the color of my eyes at all. I honestly feel like I wasted my money. I was looking for cute light grey contacts like the picture shows the model wearing, but I got barely noticeable contacts that make my eyes look slightly hazel. So, if you're looking for grey contacts and you've got brown eyes, dont buy these ones.
