The Original Penguin THE STEWART Eyeglasses bring retro-inspired style and everyday comfort together in a versatile oval frame. Built from durable acetate with a full-rim design, these prescription-ready frames are designed for men who want eyewear that works as hard as they do—whether you're at the office, out with friends, or tackling weekend errands.
Classic Oval Shape That Flatters Most Faces
The oval lens shape is one of the most universally flattering styles in eyewear. The STEWART's gently rounded silhouette softens angular features on square and heart-shaped faces while adding subtle definition to round faces. With a 49mm lens width and 20mm bridge, these frames offer a medium fit that sits comfortably without sliding or pinching. The 140mm temples provide balanced support throughout the day.
Available in seven distinct colors—including Tortoise, Liquid Tortoise, Crystal, Black, Mirage Grey, Bosphorus Green, and Surf The Web Blue—you can choose a look that matches your personal style. The tortoise patterns deliver vintage warmth, while the crystal and colored acetates add a modern edge.
Acetate Construction Built to Last
These frames are made from high-quality acetate, a plant-based material prized for its durability, lightweight feel, and hypoallergenic properties. Acetate frames resist wear better than basic plastic, maintain their shape over time, and offer a smooth, polished finish that feels comfortable against your skin. The full-rim construction provides excellent lens support and works well with all prescription strengths, including progressive and bifocal lenses.
"These are the exact same glasses that they were selling at my eye doctor's, for so much more." — Amazon customer review
Prescription-Ready for Your Vision Needs
The STEWART is fully compatible with prescription lenses, including single-vision, progressive, and bifocal options. The oval shape provides ample vertical space for progressive lenses, making these frames an excellent choice if you need multifocal correction. You can also add anti-reflective coatings, blue light protection, or transition lenses to customize your eyewear for your lifestyle.
Original Penguin has been blending American heritage style with modern design since 1955. The STEWART continues that tradition with clean lines, quality materials, and a laid-back confidence that never goes out of style. These frames come with a protective case and cleaning cloth, and they're backed by a one-year manufacturer's warranty.

I had been looking to replace the exact frames that I had from my previous eye doctor. Since I moved to another state I could not find them locally. I was thrilled to find them at Designer Optics. Shipping was very fast, and I couldn’t be happier.

Frequently Asked Questions
Are the Original Penguin THE STEWART eyeglasses prescription-ready?
Yes, the STEWART frames are fully prescription-ready and compatible with all lens types, including single-vision, progressive, and bifocal lenses. The oval shape provides ample vertical space for progressive lenses, making them an excellent choice for multifocal prescriptions. You can customize your lenses with anti-reflective coatings, blue light protection, or transition options.
What face shapes work best with oval eyeglasses like the STEWART?
Oval frames are universally flattering and work well with most face shapes. They're particularly excellent for square and heart-shaped faces, as the rounded edges soften angular features. They also complement diamond and oblong faces by adding balance. The only face shape that might prefer more angular frames is round, though many people with round faces still wear oval glasses successfully.
What are the measurements of the Original Penguin THE STEWART frames?
The STEWART features a 49mm lens width, 20mm bridge width, and 140mm temple length. This is considered a medium fit suitable for most adult men. The oval lens shape provides good coverage without being oversized, and the proportions work well for everyday wear.
What material are the STEWART eyeglasses made from?
The STEWART frames are made from high-quality acetate, a durable plant-based material. Acetate is hypoallergenic, lightweight, and more durable than basic plastic. It maintains its shape over time, resists wear, and offers a smooth, comfortable feel against your skin. The material also allows for rich, vibrant colors and patterns.
How many color options are available for the STEWART?
The Original Penguin THE STEWART is currently available in seven colors: Tortoise, Liquid Tortoise, Crystal, Black, Mirage Grey, Bosphorus Green, and Surf The Web Blue. This range includes classic tortoise patterns, neutral tones, and bold accent colors to match different personal styles and wardrobes.

Comparing the Original Penguin THE STEWART to Similar Frames
If you're considering the Original Penguin THE STEWART, you might also be weighing a few other frames in the same collection. Here's how the STEWART stacks up against its closest competitors.
THE STEWART vs. THE MURPHY
Both frames feature the same oval shape and acetate construction, but the MURPHY has a smaller 46mm lens width compared to the STEWART's 49mm. If you have a petite to medium face, the MURPHY might offer a better proportional fit. However, if you prefer more coverage or have a medium to larger face, the STEWART's slightly larger lens provides better balance. The STEWART also offers seven color options versus the MURPHY's more limited selection, giving you more flexibility to match your personal style.
THE STEWART vs. THE SURPRISE
The SURPRISE is nearly identical to the STEWART in terms of size (48mm vs 49mm lens width) and price range. Both are oval acetate frames with the same retro-inspired aesthetic. The main difference comes down to color selection—the STEWART offers seven colors while the SURPRISE has four. If you're drawn to options like Surf The Web Blue or Bosphorus Green, the STEWART gives you more variety. Otherwise, these frames are so similar that your choice will likely come down to which specific colorway appeals to you most.
THE STEWART vs. THE CLYDE
This comparison comes down to shape preference: oval vs. square. The CLYDE features a square frame that adds more structure and definition, making it ideal if you have a round or oval face and want to add angles. The STEWART's oval shape, on the other hand, is more universally flattering and offers a softer, more classic look. The CLYDE has received excellent customer reviews with many repeat buyers, and it offers nine color options. If you're torn between the two, consider your face shape—square frames work best for round faces, while oval frames flatter square and heart-shaped faces.
Our recommendation: Choose the STEWART if you want a universally flattering oval shape with excellent color variety, especially if you have a square or heart-shaped face. Its 49mm lens width offers solid coverage for medium faces, and the seven color options ensure you'll find a match for your style. The acetate construction and prescription compatibility make it a reliable everyday frame that works for any occasion.
