The Ruth is a square frame with the slightest cat-eye that is timeless. The Ruth has plastic ultra-thin and scratch-impact resistant lenses, for superior comfort, clarity and durability. It’s the perfect blend of style and sophistication. The blue light lenses help filter out the blue light emitted by phone, computer, and tablet screens, reducing the strain on your eyes. As with all Gabriel + Simone reading glasses, they come with a case and a cleaner cloth.
