Facial paralysis often makes it hard to close your eyes. If you can’t close them completely, it’s important to take special care of your eyes even before you visit a doctor. This may prevent permanent eye damage. You should:
Use a moisture chamber at night.
Use an eye patch or eye taping when sleeping after discussing this with your eye doctor.
Use eye drops such as “artificial tears” frequently during the day.
Use over-the-counter eye ointment at night. Within seven to 10 days of starting the ointment, be sure to see an eye doctor.
Wear wraparound sunglasses when outside.
