Repairing eyeglass frames can be a tricky business, whether done at the store or at home. Some of the parts involved are delicate and tiny, such as the hinge assembly and screws.
Titanium is a strong and lightweight metal with good resistance to corrosion, making it a good candidate for durable eyeglass frames. It's only about 60 per cent as dense as iron and is non-magnetic.
An optometrist's office or eyeglass sales centre usually offers frame repair service. Either they do in-store repair or ship the frames to a repair facility. Methods of repair include soldering and welding, terms which most people are familiar with. Brazing is a less-well-known method of repair that can lead to high-quality results. Brazing joins pieces with heat in excess of 449 degrees Celsius, and then uses a filler metal which has a lower melting temperature than the base metal.
You can buy frame repair kits in chemists, department stores and hardware stores. Typically, a kit includes a tiny screwdriver and generic replacement screws. Using a strong glue is the safest and least expensive method for joining frame parts at home. Soldering requires more practice and can result in skin burns if you are not careful.
