ThinOPTICS Keychain Reading Glasses
ThinOPTICS, you're so kind to the elderly. Not only do these keychain reading glasses fold flat to eliminate the bulk of carrying readers around, but they also latch onto a set of keys so the likelihood of my mama forgetting them at home is reduced by a good...10, 15 percent.
Just kidding, Mama.
I previously saw ThinOPTICS slipped into an adhesive sleeve for the back of your phone. I thought that was a nifty place to stick a spare pair of reading glasses, but the keychain version is probably better for those who don't want anything, even shatter-proof polycarbonate frames as thin as 2 credit cards and lighter than a nickel, slapped on to their already hefty phone.
ThinOPTICS glasses use Flex-Fit Technology, a feature they invented that pairs a titanium alloy bridge made from nitinol with independent-suspension nose pads. The result is bridge that can flex separately from the nose pads, which also flex and grip, so the readers fit comfortably both pushed high or set low on most noses. Lenses, available in your choice of 4 strengths, are made from the same optical-grade polycarbonate as prescription lenses.
ThinOPTICS glasses come with the keychain case. To store, fold the glasses in half and slide them in.
