I have a pair of soft coloured contact lenses that are Plano (non-prescriptive) and I've only worn them once for 3-4 hours. They fit well, were comfortable, and I had no trouble. I want to wear the contacts to school, but that would mean wearing them from 7 am to 4-5 pm! And that's 9-10 hrs! Is it okay to wear them for that long? I don't want to wear them daily, just once a month.
I did some research on the Internet, and the majority of people recommend 8 hrs. What scares me is the risk of bloodshot eyes, ulcers, blindness and all that scary stuff!
