This was my first pair of circle lenses ever because of my astigmatism and strong prescription. I was worried these wouldn't be comfortable in the end. I ended up being thoroughly impressed. I wore these all day (and unexpectedly all night) at a convention and didnt have any issues. They feel like my regular prescription contacts and give me zero discomfort save for sometimes my eyes getting a little dry. I highly recommend soaking them in contact solution for 3 days before wearing, it makes a difference in comfort level. Overall I'd buy again and I highly recommend.
