The choice of eyeglasses is one of the most personal style decisions we make. They are a functional necessity, a fashion statement, and an extension of our personality. While design, color, and lens technology are crucial, the fundamental character and performance of a pair of glasses are dictated by their core material. Today's optical market is dominated by five key players, each with unique properties: the classic Acetate Frames, the sporty TR90 Frames, the versatile Metal Frames, the premium Titanium Frames, and the resilient Stainless Steel Frames. Understanding the distinct advantages of each is the first step to finding your perfect pair.
