titanium is a silver-gray metal that's lightweight, durable, strong and corrosion-resistant. It has been used for everything from the Gemini and Apollo space capsules to medical implants such as heart valves.

Titanium eyewear can be produced in a variety of colors for a clean, modern look with a hint of color. And they're hypoallergenic.

Stainless steel frames and surgical stainless are another alternative to titanium. Qualities of stainless steel frames include light weight, low toxicity and strength; many stainless steel frames also are nickel-free and thus hypoallergenic.

The main difference is how they can react with the body. Stainless steel is an alloy and contains nickel. A lot of people will have an allergic reaction to nickel, which is why with costume and cheaper jewlery, you hear of people getting a rash or red marks from something made out of stainless steel.

Titanium is an element, there in no other metal there, just pure titanium. Is is very, very rare that titanium will cause an allergic reaction with the skin, so there is much less a chance of any rash or redness occurring from a piece of titanium jewelry.
