Depending on how heavy the glasses are, I consider allowing my patients wearing glasses if they have to 4 weeks after rhinoplasty. I often break the nasal bones during surgery (osteotomies) and it's important to give the bones time to heal, which takes 4-8 weeks. If something really heavy goes on them or hits them, they could in theory move. At 4 weeks, I assess my patients for any tenderness to palpation along the edges of the nose. If there is no tenderness, that suggests the bones have undergone clinical healing of the bone, though they may not yet be 100% full strength. At that time it is ok to wear light glasses. Otherwise if at all possible I ask my patients to wait 6-8 weeks to be extra safe, but not all patients are able to wear contact lenses instead so sometimes some flexibility is needed. Additionally, if glasses are heavier, a piece of tape to hold them to your forehead so that all of the weight is not on the nose helps minimize any risk. -David Mattos, Harvard-trained plastic surgeon
