Left Eye Feels Like Something's in it? Is it GPC?

First of all, if you do have GPC it doesn't mean that you can't wear contacts forever! It is usually caused by an allergic reaction ,sometimes, a dirty lens,,,it depends. Stop wearing your contacts until you see your doctor to prevent further or more severe problems. wear your back up glasses and give your eyes a rest.keep the contacts to show the doctor but DO NOT re-use..dispose of them AFTER you see him. You still don't know if thats what it is so don't freak, just take the proper precautions. The doctor may give you an antibiotic or antibiotic/steroid drop to clear up the problem then give you a NEW pair. Good Luck!
