DESCRIPTION RATINGS & REVIEWS PRESCRIPTION GUIDE

The Original Penguin The Locke Eyeglasses bring 1950s-inspired style into your everyday rotation with a gradient acetate design that's hard to miss. The frame starts with rich color at the top—whether you choose the warm brown-to-clear Grey Sunset, the ocean-inspired Deep Water blue fade, or the sophisticated grey Castle Rock—and transitions smoothly to crystal clear at the bottom. It's a two-tone effect that adds depth without feeling loud, and it pairs just as well with a button-down as it does with a weekend tee.

The rounded rectangle shape hits that sweet spot between classic and contemporary. It's wide enough to make a statement but not so bold that it overwhelms your face. The full-rim acetate construction means these frames are built to last—acetate is a plant-based material that's more durable and flexible than standard injection-molded plastic, so they hold up to daily wear without losing their shape or color. The thick temples curve gently inward for a secure, comfortable fit behind the ears, and the signature Original Penguin hardware at the hinges adds a subtle brand detail.

"I love these glasses and I get so many compliments when I am wearing them!" — Cool Frames customer review

These frames are prescription-ready and work with single-vision, progressive, bifocal, and reader lenses. The 49mm lens width and 21mm bridge fit most medium faces comfortably, and the full-rim design provides plenty of surface area for thicker prescriptions if you need them. You can add anti-reflective coatings, blue light filtering, or transition lenses to customize them for your lifestyle.

Original Penguin has been blending American heritage style with modern comfort since the 1950s, and The Locke continues that tradition. The gradient acetate gives these frames a vintage soul with a fresh twist—they're the kind of glasses that work in a Zoom meeting and at happy hour without missing a beat. The frames ship with a protective case and cleaning cloth, and they're backed by a manufacturer's warranty for peace of mind.

Defective frames

I was excited to have received my new glasses. I loved the look of them. However, The temple arm flared out too much to properly fit my head. And after wearing them only a week, the bridge snapped!! I now have a $650 pair of glasses that are not usable.

Frequently Asked Questions

Are the Original Penguin The Locke frames prescription-ready?

Yes, The Locke eyeglasses are fully prescription-ready and compatible with single-vision, progressive, bifocal, and reading lenses. The full-rim acetate construction provides a stable base for a wide range of prescription strengths, and you can add lens coatings like anti-reflective, blue light filtering, or photochromic transitions during checkout.

What is the gradient fade design on The Locke frames?

The Locke features a gradient acetate design where the frame color transitions smoothly from a darker shade at the top to clear at the bottom. This two-tone fade effect is a nod to 1950s and 1960s eyewear styles and adds visual depth without being overpowering. The gradient is built into the acetate material itself, so the color won't chip or fade over time like painted frames.

What face shapes work best with The Locke eyeglasses?

The Locke's rounded rectangle shape is especially flattering for people with round or oval faces, as the straighter lines add definition and structure. The 49mm lens width and balanced proportions also work well for medium-width faces. If you're unsure about fit, the acetate material can be adjusted by an optician for a more customized fit.

Why are acetate frames better than regular plastic?

Acetate is a plant-based material that's significantly more durable, flexible, and hypoallergenic than standard injection-molded plastic. Acetate frames are made by layering and fusing sheets of cellulose, which creates a stronger structure that resists breakage and holds its shape over time. The color is embedded in the material rather than painted on, so it won't chip or fade with daily wear.

What are the frame measurements for The Locke?

The Original Penguin The Locke has a 49mm lens width, 21mm bridge width, and 140mm temple length (49-21-140). This is considered a medium fit that works well for most adult faces. The full-rim design and rounded rectangle shape provide good coverage without feeling oversized.

Is Original Penguin a good eyewear brand?

Yes, Original Penguin is a reputable premium lifestyle brand with roots dating back to the 1950s. The brand is known for blending retro-inspired design with contemporary comfort and quality materials at accessible price points. Original Penguin eyewear is manufactured by Kenmark Eyewear and comes with a manufacturer's warranty, and customer reviews consistently praise the frames for their style, durability, and value.

How The Locke Compares to Other Original Penguin Frames

If you're considering the Original Penguin The Locke, you're probably weighing a few other frames in the same collection. Here's how The Locke stacks up against its closest competitors.

The Locke vs. The Murphy

Both frames share Original Penguin's retro-inspired aesthetic and premium acetate construction, but The Murphy has a smaller 46mm lens width compared to The Locke's 49mm. If you have a narrower face or prefer more compact frames, The Murphy might be the better fit. However, The Locke's gradient fade design is more distinctive and eye-catching, and the larger lens size provides better coverage for most medium-width faces. The Murphy runs slightly higher in price without offering the unique two-tone acetate that makes The Locke stand out.

The Locke vs. The Clyde

The Clyde is one of Original Penguin's best-sellers, and for good reason—it has excellent customer reviews and comes in 9 color options. The key difference is shape: The Clyde has a square frame that creates a bolder, more angular look, while The Locke's rounded rectangle is softer and more versatile. If you have a round face, The Locke's shape will add more definition, whereas The Clyde's square design works better for oval or heart-shaped faces. The Locke's gradient acetate also gives it a more unique, vintage-inspired character that the solid-color Clyde doesn't match.

The Locke vs. The Stewart

The Stewart and The Locke share the same 49mm lens width and similar price points, but the shape and style differ significantly. The Stewart has a more traditional oval shape that's understated and conservative, while The Locke's rounded rectangle is more structured and modern. The biggest differentiator is The Locke's gradient fade design—if you want frames that generate compliments and stand out in a subtle way, The Locke is the clear winner. The Stewart is a solid choice if you prefer a quieter, more classic look, but it doesn't have the same visual interest.

Our take: The Locke offers the best of both worlds—a versatile rounded rectangle shape that flatters most faces, combined with a distinctive gradient acetate design that sets it apart from more generic frames. At the same price point as The Stewart and slightly less than The Murphy, it delivers more visual interest and compliment-generating style. If you want frames that work across professional and casual settings while still having a unique retro character, The Locke is the standout choice in the Original Penguin collection.
