Created to complement the active lifestyle, the Chesterfield collection features casual, contemporary--and comfortable--eyewear for men, women and children.This all-American brand offers a wide variety of design options, targeted to adults with a young, relaxed attitude, and children and teens who seek to emulate them. Safilo introduces FLEXOLITE MEMORY METAL to the Chesterfield Ophthalmic, Sun and Kids collections. Composed of 56% nickel and 44% titanium, this specific blend of materials ensures that the frame is extremely flexible (and able to return to its original shape), but is also stable enough to be properly adjusted and fit securely. In addition, frames made of Flexolite Memory Metal are resistant to corrosion and fatigue. The Chesterfield Ophthalmic collection features clean lines in softer, geometric shapes. Frame materials include plastic, metal and lightweight titanium. Many styles feature spring hinges. Select men's and children's styles include the innovative Flexolite bridge, which provides maximum flexibility and reduces breakage. Clip-ons are available with some styles. The Chesterfield Sun collection also features a variety of contemporary styles, including wraps and aviators. All sun styles feature polarized lenses.
