These CH30 XL eyeglasses from Chesterfield are specially constructed for the wearer with a large head. The full-rim rectangular rims are crafted from acetate, a plant-based plastic that’s lightweight and hypoallergenic. The slim temples are made from a combination of plastic and corrosion-resistant Monel, a metal alloy that retains its shape. Flexible spring hinges hold their initial adjustment for a secure fit and a comfortable feel. Timeless in design, yet contemporary in style, these Chesterfield glasses add a touch of class to your everyday look.
