Our Ivy readers add an elevated look to any wardrobe by mixing tortoise and solids. The rectangular tortoise front comes in a variety of colors, each with a complementary solid-colored temple. Spring hinges provide long-lasting comfort. These glasses are part of our Focus™ Eyewear collection, which helps protect your eyes from strain and damage caused by the high-energy visible (HEV) blue light emitted by modern electronic devices. The lenses will filter 40% or more of the most harmful blue light without any color tints.
