EE's were driving from main office to the plant to begin their shift. EE felt something in his eye thought it was a bug. Arrived at the plant another EE helped IEE at the eye wash station. It started to swell shut, could not see what it was. EE's wife took him to the ER Dr. did not find anything. They washed it out and he left ER He has a follow-up visit at the eye doctor.
