The PLASTICS II NTC-1 eyeglasses deliver classic rectangle styling and practical features at a price that makes prescription eyewear accessible. Available in versatile black and tortoise acetate finishes, these full-rim frames offer a clean, professional look that works from the office to everyday wear.
The NTC-1 is built from cellulose acetate, a plant-based material known for being more durable and flexible than standard plastic frames. Acetate resists pressure better and can bend further without breaking, making these frames a smart choice for daily use. The full-rim design provides maximum stability for your lenses, while the material itself is lightweight and comfortable enough for all-day wear. Acetate frames typically last three to five years with regular care, and they’re hypoallergenic for sensitive skin.
These frames feature spring hinges that allow the temples to flex outward beyond the standard 90-degree angle. This flexibility serves two purposes: the frames adapt to different head sizes for a secure yet comfortable fit, and the give in the hinges protects against breakage when you’re putting them on or taking them off. Spring hinges reduce stress on the frame, making them less likely to break than inflexible hinges—a real advantage if you wear your glasses all day or lead an active lifestyle.
The NTC-1 is available in lens widths from 49mm to 60mm, with a 17mm bridge and temple lengths ranging from 135mm to 150mm. Rectangle frames like these are particularly flattering on oval and round face shapes because the straight lines add definition. These frames accept single vision, bifocal, and progressive prescription lenses, making them a versatile option whether you need distance correction, reading help, or both.
