Magnesium alloy frames are spectacle frames made from a metal composite where magnesium is the main component. Magnesium is the lightest structural metal available making it a desirable material for eyewear. The magnesium is alloyed with other metals to increase its strength and durability.

Frames made from this material are exceptionally light which greatly reduces pressure points and enhances comfort. Magnesium also resists corrosion and is durable when properly finished. It allows manufacturers to create thin strong frames without adding significant weight.
Magnesium alloy is lighter than titanium providing a slightly less noticeable feel on the face. However titanium is usually more flexible and more resistant to impact damage. Both are premium materials but magnesium saves on pure weight.
Magnesium alloy frames require specialized manufacturing. If the metal is not properly coated, it can be prone to corrosion from moisture. If a frame breaks, it can be difficult or sometimes impossible for an optician to repair due to the unique properties of the alloy.
Magnesium alloy is a metal used only for rigid frames, it cannot be used in soft contact lenses. Frames are still relevant to contact lens wearers. Choosing comfortable, feather-light magnesium glasses as a backup allows your eyes to rest from contact lens wear and provides necessary vision correction on days when contacts cannot be worn.
Yes, most high-quality magnesium alloys are hypoallergenic, especially when coated with an appropriate protective finish.
They are highly resistant to corrosion and lightweight. While strong, they can be difficult to repair if severely bent or broken.
No, magnesium is lighter than aluminum, making it one of the lightest metals used in modern eyewear.
If your magnesium frames feel unusually hot or cold against your skin, check the integrity of the finish. Magnesium has high thermal conductivity; if the protective coating is scratched, the metal can react with skin oils, causing minor irritation.
