Days back i was changing light bulb when it suddenly fell and broke.From then i am having doubt that i may have shards of glass in eye, no redness is there! just wanna ask whether it is possible that glass is in eye and one behaves normal following his usual routine, every now and then my mind comes back to the eye about the doubt! also i feel that when i focus closing one eye at a time i can see for less time than the other eye! it somewhat blinks before tha. other ! is this my doubt or something wrong  like really glass is there!
