Prescription Glasses or Sunglasses that are heavy or have tight nose pads may slightly push on the newly shaped nose bones if worn before the bones have healed securely (which can take up to 8 weeks). · If pressure is significant it could cause some deformity of the nose bones that were operated on. Therefore, while you should be able to resume wearing lighter glasses earlier, you must observe precautions:- - Consider modifying your glasses by spreading the nose pads so there is no excess or firm pressure on the bridge or sides of your nose.. If your glasses are essential for vision, you may choose to have one pair of glasses modified prior to your surgery. - If needed, hold the glasses in position by taping the bridge of your glasses to your forehead with skin coloured tape (available at pharmacies). You can wear contact lenses as soon as you feel comfortable after surgery. Check with your doctor if you have any concerns or questions.
