These Portable Keychain Reading Glasses feature optical-grade, polycarbonate lenses (for use in high-end prescription glasses) that are shatter-proof, lighter than a nickel and as thin as 2 credit cards.
The ultra-flexible, titanium alloy (nitinol) bridge is 10x more elastic than steel springs and is guaranteed never to break.
This flex-fit technology combines the flexibility of titanium alloy with the independent-suspension of the nose pads, delivering a universally comfortable yet stable grip on any nose, whether they're worn up high or down low.
Product includes the reading glasses & a handy keychain case to keep your flexible glasses safe and attached to you wherever you go.
