Over time, the screw which holds the arm to your frame may become loose. As we use a special LockTight Screw System, this is a rare occurrence. However, if you do need your screws to be tightened, we recommend visiting your local optician to have them professionally adjusted. Some materials are difficult to adjust and can be fragile, so it is best to leave the adjustment process to an optician.
Do not try to fix your glasses using internet instructions - you will likely damage them and may void your warranty. If you need your sunglasses or glasses adjusted, please contact our Customer Service Team. We use specialist equipment to adjust eyewear frames, as they can be difficult to adjust without it.
