The 1.591 PC Polycarbonate Bifocal Lens series is designed for wearers who require both distance and near vision correction. Available in Round Top, Flat Top, and Invisible Bifocal designs, these lenses provide clearly defined optical zones to support daily reading, working, and walking activities.
Made from high-impact polycarbonate material, the lenses are lightweight yet durable, ensuring safe and comfortable wear. The Invisible Bifocal option offers a more natural appearance while maintaining functional performance, reducing the visible segment line associated with traditional bifocals.
