The Burberry Knight 4358 sunglasses bring bold British style to a modern square frame. These men's sunglasses feature a full-rim acetate construction with a 57mm lens width, 18mm bridge, and 145mm temples—proportions that work well for medium to larger faces. The frame is made from durable nylon and propionate acetate, keeping weight down while maintaining structural integrity.
What sets the Knight apart is the branding. The wide temples feature the Burberry name in raised lettering—a design choice inspired by 70s eyewear but executed with a contemporary edge. You'll find this detail across all seven color options, from the black frame with yellow lenses (a high-contrast look that cuts glare in bright conditions) to the matte black with polarized dark grey lenses for maximum glare reduction on water or pavement. The orange and blue variants add a pop of color, while the classic havana with brown lenses offers a more traditional aesthetic.
The lenses provide full UVA and UVB protection, and the frames are prescription-ready. The injected temples curve gently for stability behind the ears, and the standard bridge design fits comfortably on most nose shapes. At this price point, you're getting authentic Burberry craftsmanship—made in Italy with attention to fit and finish—without the markup you'd see at full retail.
Square frames like the Knight work best on round or oval face shapes, where the angular lines add definition. If you have a square or angular face, you might prefer something with softer curves. The 57mm lens width is considered large, offering good coverage and a confident, statement-making presence.

Frequently Asked Questions
Are Burberry Knight 4358 sunglasses prescription-ready?
Yes, the Burberry Knight BE4358 sunglasses are prescription-ready. The full-rim acetate frame can accommodate single-vision, progressive, and polarized prescription lenses. The 57mm lens width and 46mm lens height provide enough vertical space for progressive lenses if needed.
What size are Burberry BE4358 Knight sunglasses?
The Burberry Knight BE4358 measures 57mm lens width, 18mm bridge width, and 145mm temple length (57-18-145). This is considered a large fit, suitable for medium to wider faces. Sunglass Hut classifies this as an XL size designed for those with wider heads and higher nose bridges.
Do Burberry Knight sunglasses have UV protection?
Yes, all Burberry Knight BE4358 sunglasses provide 100% UVA and UVB protection. The lenses block harmful ultraviolet radiation to help protect your eyes from long-term sun damage, regardless of whether you choose the standard or polarized lens options.
What face shape works best with square sunglasses like the BE4358?
Square sunglasses like the Burberry Knight BE4358 work best on round and oval face shapes, where the angular frame lines add definition and balance to softer facial features. If you have a square or angular face with a strong jawline, rounder frame styles typically provide better contrast and a more flattering look.

Polarized lenses are available on select Burberry Knight BE4358 variants, specifically the 346481 (matte black with polar dark grey lenses). The other color options—including the black/yellow, orange, blue, and havana—come with standard UV-protective lenses that are not polarized.
What material are Burberry BE4358 frames made from?
The Burberry Knight BE4358 frames are made from injected nylon and propionate acetate—a durable, lightweight plastic material.

Burberry Knight 4358 vs Similar Square Sunglasses
Knight BE4358 vs Carnaby BE4337
Both the Knight BE4358 and Carnaby BE4337 are square acetate sunglasses from Burberry's men's collection, but they take different approaches to branding and design. The Knight features bold, raised Burberry lettering on wide temples—a 70s-inspired detail that makes a statement. The Carnaby, by contrast, uses seven layers of acetate to create a subtle icon stripe effect along the rim, with signature bolt details that reference Burberry's jewelry line.
Size-wise, the Knight is slightly larger (57-18-145 vs 56-17-145), making it better suited for wider faces or those who want maximum coverage. The Carnaby's medium fit is more versatile. If you prefer understated luxury with refined details, the Carnaby delivers. If you want eyewear that announces itself, the Knight's prominent branding is the move.
Knight BE4358 vs BE4291
The BE4291 offers a more traditional square frame without the Knight's distinctive wide-temple branding. Both are full-rim acetate frames at similar price points, and both are prescription-ready with full UV protection. The Knight stands out with its larger 57mm lens and bolder aesthetic, while the BE4291 takes a more conservative approach. Choose the Knight if you want a modern, logo-forward look; consider the BE4291 if you prefer classic Burberry style without the prominent branding.
Why Choose the Knight BE4358?
The Knight BE4358 is the right choice if you want a larger square frame with bold branding and contemporary style. The 57mm lens provides excellent coverage, the color range includes both classic and statement options (including polarized), and the price point is competitive for authentic Burberry eyewear. It's a confident, modern frame that works well on round and oval face shapes.
