Repairing an expensive pair of Dior sunglasses does not have to be complicated. A return to the retailer they were purchased from will simplify the process. Dior sunglasses are sold with a one year warranty on manufacturing defects, which means they can be sent back to the manufacturer for repair. Simple Dior sunglass repairs may occur through local repair centers.

There are two ways in which to work with Dior sunglass repairs when the glasses are under warranty—through the retailer and through the manufacturer. Repairs are not generally made by the retailer if the item is within warranty, although simple repairs, like missing screws or loose parts, may be made by some retailers on site. The retailer can send the glasses to the manufacturer for the customer or will give the customer the address to do so. The customer can also go directly to the manufacturer by calling Safilo (Dior's licensed manufacturer) at 877-228-5818 and requesting assistance. Safilo will then provide directions on where to send the sunglasses. Safilo will repair items that are out of warranty but this may require paying for the repair.

Simple repairs can be made at home using a sunglass repair kit. These kits contain a variety of screws, nuts and nose pieces. They also contain a tool to assemble and tighten the repair with. Repair kits are not usually made for a specific manufacturer like Dior. Kits will only supply the pieces for simple repairs and not proprietary parts like nameplates or decorative attachments. Sunglass repair kits can be found through most eyeglass and sunglass stores. They can sometimes be found in variety or drug stores, too. The kits can contain a mixture of gold tone and silver tone parts or may contain only one or the other.

Local eyeglass repair can be found in many eyeglass centers and through frame sellers. Personnel in these stores are often trained to make simple repairs. LensCrafters and Pearle Vision are two of the many choices for walk-in sunglass repair. Having sunglasses repaired through these retailers may be ideal when the warranty has expired. Sometimes retailers will not charge for simple repairs. If the customer has purchased a specialty part directly from the manufacturer but does not know how to attach it, a local repair center may be able to assist in the repair.
