This prescription-ready addition to the Latch eyewear collection has a stainless steel underwire for a faux semi-rimless look, and it comes with the handy kick-up latch hinge that clips to your shirt. A comfortably lightweight O Matter frame, Latch Key has the classic notch bridge and smoothly rounded lenses that make this family so popular. The latch hinge allows you to securely stow your eyeglasses while on the go, keeping you moving through your day. We finished the frame with our new Grip Fit nose pads, and we made them clear for a seamless look. Latch Key is available in small or large size so you can enjoy an optimized fit. WARNING: This product can expose you to chemicals including nickel, which is known to the State of California to cause cancer.
