How long are LASIK goggles worn? LASIK goggles will be worn for roughly four days, though there are different instructions to consider during the healing process. For the first 24 hours after LASIK, the LASIK goggles should be worn at all times in order to avoid harm to the eyes. Medicated eye drops should be the only thing that comes into contact with the eyes in that first day of surgery. In the three to four days following surgery, patients will usually only be instructed to wear their LASIK goggles at night to avoid accidental rubbing and contact. When outdoors, patients should wear sunglasses in order to protect the eyes from the harshness of the light.
