Anytime you watch a movie that has some sort of librarian or academic of mature age, chances are, they’ll be shown bumbling about for their reading glasses at least once. Which is understandable because reading glasses are easy to forget. Never forget yours again with the ThinOptics, the reading glasses that attach to your phone.

The glasses themselves don’t attach, instead the carrying case can be attached to any phone or phone case in addition to being carried in your pocket. The glasses are much thinner and have a flexible bridge that allows them to fold into a small size and fit inside of a case. This case is what actually attaches to your phone. The whole set up weighs less than the change you have in your pocket and is as thin as your credit card.

Most people always know where their phone is and even if they don’t, it’s always a just a ring away. Now you can throw in your reading glasses to keep them on hand as well. ThinOptics come in a variety of colors and lens strength. They start at $24.95.
