Generally, the frame with the feature light weight has nothing to do with the brand. It has something to do with the frame materials. As I know that plastic performance frames are lightweight and durable, which is why they are favored by athletes and people who participate in outdoor and recreational activities. Another light weighted frame are titanium frames. This premium metal is very strong, durable, corrosion-resistant, and is 40% lighter than other metals. It's also hypoallergenic, making it a nearly perfect material for eyeglass frames. Titanium frames are available in several colors.
