Yes. titanium glasses are more expensive than others because they are strong. You can bend it without damaging. What's more,it can return to its original shape. titanium glasses are also lightweight and naturally hypoallergenic. So people will find more comfortable to wear titanium glasses. But you say your titanium glasses cost you $1000 which sounds too expansive. I think a pair of titanium glasses usually costs several hundreds dollars according to the place you get it.
