Had a weird one at the weekend. Rolling up to a roundabout at maybe 30 I opened my visor half an inch - half a second later a fly went into my left eye and I made an effeminate noise - I had to stop anyway so opened my lid and rubbed my eye with a gloves hand. The pain went and I could see so off I went. Two days later I was in the shower and noticed my eye was stinging , rubbed it and a very gunked up fly came out eughhhh
