Nations Optics Lenses offer a smart blend of comfort, durability, and visual clarity. Crafted from CR‑39 plastic, these lenses are lightweight, highly transparent, and boast excellent optical quality, making them ideal for everyday wear. The hard coat provides a tough, scratch-resistant surface for long-lasting performance. Featuring a bifocal design, these lenses offer dual-use functionality—distance vision in the upper segment and near vision in the lower. The fixed grey tint ensures softer glare and enhanced comfort in bright conditions, while still preserving clear vision indoors.
