For me, wearing contacts was just generally irritating. Like for example, I noticed that when I wear glasses I'm going to be less light sensitive, have less eye pressure, and less eye strain on a given day than if I'm wearing contacts.

At this point in time, I found it sometimes difficult to stay within my limits because I was still figuring out what they were and in school, so wearing contacts definitely worsened any setbacks I was going to have, I'm not sure if they caused any on their own though. But if my activity levels were at my threshold for when I was wearing glasses, wearing contacts would decrease that threshold, so if I continued with the same level of activity with contacts, I would get worse.
