Jim, the eye just doesn't 'explode'. There are some things around the eye that might make a 'pop' sound including the
tearTears again
Tears again gel drops
Tears again night & day
Tears naturale
Tears naturale forte
Tears naturale free
Tears naturale ii
Tears naturale pm
Tears plus
Tears renew
Tears renewed sac and sinuses. A 'stye' can 'pop'. In any case, as I read your post the pain and irritation have stopped. If that is the case and your vision is good and everything is back to normal, you should be able to wait till tomorrow and call your ophthalmologist's office.
For your information, all ophthalmologists maintain 24 hr/day, 7/day per week answering service and provision for emergency care. If you have a true emergency you should feel free to call the ophthalmologist on call for your Eye MD.
