Searching for a practical and stylish frame is never easy, at least not until you've checked out the ULTEM F9106 Black prescription glasses! Narrow rectangular shaped lenses are set in a semi-rimless glossy black metal frame with outer edges that wrapped around the sides slightly. Matte black temple pieces that follow are made of one of the most state-of-the-art materials: a durable and ultra flexible plastic that has a memory flex allowing the frames to bounce back to their original shape. The innovative Ultem material has never demonstrated a risk of allergy and is FDA and CE approved. These frames also feature adjustable nose pads and have black colored stem tips that can be molded to hold their shape allowing the temple pieces to hug the curve of your ear any which way you like.
