A cruel eye-rony

This is a picture of Fiona Bosher the UK team member of the Oakley Transitions Ironman TeamYou may have noticed her left eye is looking a bit ' dodgy' as they say down at the local eye unit. Poor Fiona managed to pick this up while on a triathlon training camp with seven other opticians from around Europe and South Africa. A cruel twist but I suppose if you are going to have an eye problem that's the time to do it. What do you think it is? Answers please.
