These glasses block blue light emitted by electronic screens such as laptops and phones, to reduce eye strain and help you sleep better.

Since the sun emits blue light, your body is naturally tuned to be awake when you see blue light. Electronic screens also emit blue light, so if you look at screens at night, studies show that your body is confused by this and tries to stay awake. Poor sleep affects every part of your body, and can impact your heart, cognitive skills, and immune system.

The keyhole design is a classic shape, named after the keyhole-shaped gap between the bridge and nosepads.

While most eyewear frames are made of plastic and have a seam all around the edges from the injection mold, our frames are made from blocks of cellulose acetate or horn that are carved into their final shape. This process gives the frames greater flexibility, durability, and depth of color.

Spring hinges allow the arms to flex and conform to your head, for greater comfort.

Mazzucchelli CR-39 lenses. Frames suitable for prescription lenses.
