As long as you know what you are doing and keep the lenses clean and stored correctly there should not be a problem. I work as a Doctor in ED and I can tell you that those who wear contacts often have some minor abrasions around their iris's. This isn't uncommon.
What you worry about is deeper abrasions causing symptoms - such as very sore eyes and 'feeling as if something is stuck in the eye'. Then you can be at risk of infection. But that can happen with any lenses tbh.
I wear circle lenses to all my events and have never had a problem. I have lenses from various different companies. Often the lenses will be a little sore when I first put them in, but this quickly subsides.
Just always remember to wash your hands, keep the lenses clean and you will be fine
