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.
Acetate Construction Built to Last
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.
Spring Hinges for Comfort and Durability
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.
Prescription-Ready in Multiple Sizes
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.

Frequently Asked Questions
Are the PLASTICS II NTC-1 frames prescription-ready?
Yes, the NTC-1 frames are fully prescription-ready and compatible with single vision, bifocal, and progressive lenses. Simply add your prescription details during checkout, and our licensed opticians will ensure your lenses are fitted correctly to these acetate frames.
What are the benefits of spring hinges on these eyeglasses?
Spring hinges allow the temples to flex outward beyond the normal range, providing two key benefits: enhanced comfort through a more adaptable fit that accommodates different head sizes, and improved durability by reducing stress on the frame when putting glasses on or taking them off. This makes spring hinge frames less likely to break than standard hinges.
How long do acetate eyeglass frames typically last?
Acetate frames typically last three to five years with regular care, though durability depends on storage, handling, and environmental exposure. Acetate is more durable and flexible than standard plastic frames, making it resistant to pressure and less prone to breakage. Proper maintenance like storing them in a case and avoiding extreme heat can extend their lifespan considerably.
What face shapes work best with rectangle eyeglasses?
Rectangle frames are especially flattering for oval and round face shapes because the straight lines add definition and balance softer facial features. The NTC-1's classic rectangle shape is versatile enough to suit most face shapes, making it a safe choice if you're unsure which style suits you best.
What sizes are available for the NTC-1 frames?
The NTC-1 is available in lens widths of 49mm, 51mm, 54mm, 57mm, and 60mm, all with a 17mm bridge. Temple lengths range from 135mm to 150mm depending on the lens width. This range of sizes ensures a proper fit for most adults, from smaller to larger head sizes.
Are acetate frames better than regular plastic frames?
Yes, acetate frames are generally considered higher quality than standard plastic. Acetate is more durable and flexible, more resistant to pressure, hypoallergenic for sensitive skin, and available in richer colors and patterns. Acetate is also a plant-based material that's more environmentally friendly than petroleum-based plastics.

Comparing the PLASTICS II NTC-1 to Similar Frames
If you're considering the NTC-1, you might also be looking at other frames in the Modern Plastics II collection or wondering whether to spend a bit more. Here's how the NTC-1 stacks up against comparable options in our catalog.
NTC-1 vs. Other PLASTICS II Models (REMOTE, MINDY)
The entire Modern Plastics II line shares the same core benefits: acetate construction, spring hinges, prescription compatibility, and the same $30.29 price point. The main difference comes down to frame shape and style. The NTC-1 offers a classic rectangle shape that's particularly flattering on round and oval faces, while models like the REMOTE or MINDY may feature different shapes—oval, square, or modified rectangle designs. If you like the quality and price but want to explore different looks, browsing other Modern Plastics II frames makes sense. They all deliver the same durability and comfort features, so your choice comes down to which style suits your face shape and personal taste best.
NTC-1 vs. McAllister MC4519 ($65-70)
The McAllister MC4519 represents a step up in price, costing more than double the NTC-1. For that extra investment, you typically get higher-grade materials, more refined construction, and potentially longer lifespan. However, for many buyers, the NTC-1 offers the best value. You're getting genuine acetate construction with spring hinges—features that provide real durability and comfort—at a price that makes it easy to own a backup pair or replace your frames when your prescription changes. Unless you're particularly hard on your glasses or want premium styling, the NTC-1 delivers everything most people need in everyday eyewear.
Why Choose the NTC-1?
The NTC-1 hits the sweet spot for budget-conscious buyers who don't want to sacrifice quality. At around $30, you're getting acetate frames that will last three to five years with proper care, spring hinges that improve both comfort and durability, and a classic rectangle shape that works for most face types. It's prescription-ready for any lens type, available in multiple sizes, and comes in versatile black or tortoise finishes. For everyday eyewear that won't break the bank, the NTC-1 is hard to beat.
