Yep, there is a prescription eye drop you can get for bad cases and a milder non-prescription product that your pharmacist might be able to recommend... sorry don't know the names of them. I've seen so many bad cases after kids have had sand thrown in their eyes in sand-pits. Children also are more prone to it when they are generally 'run-down' or their immunity is compromised from other illnesses. It's incredibly contagious too so make sure you wash your own fingers after applying the drops.... sorry if you already know this! I've caught it myself off children that's all
