What is the common name used for cellulose acetate in eyewear?

  1. A. Plexiglass

  2. B. Polycarbonate

  3. C. Lucite

  4. D. Zyl

The correct answer is: D. Zyl

Cellulose acetate is commonly known as Zyl in the eyewear industry. It is a popular material used for making eyeglass frames because of its durability, flexibility, and wide range of color options. Plexiglass is a brand name for acrylic plastic, not cellulose acetate. Polycarbonate is another type of plastic often used for lenses, not frames. Lucite is a brand name for acrylic resin and not associated with cellulose acetate frames.
