The Diff BELLA Sunglasses are the brand's bestselling oversized square frames for women—and for good reason. These sunglasses combine a bold, face-framing silhouette with everyday wearability, featuring hand-cut acetate fronts paired with sleek stainless steel temples that balance substance with comfort. The BELLA's generous 54mm lens width creates that statement-making look without overwhelming your features, flattering oval, heart, and round face shapes beautifully.
What you see in the photos tells the story: the tortoise variant showcases rich amber tones with gold-toned metal temples, while the rose colorway offers a soft, translucent finish—both with gradient lenses that transition from darker at the top to lighter below, perfect for reducing glare while maintaining visibility. The square shape features softly rounded corners that keep the look approachable rather than severe, and the integrated nose pads ensure a stable, comfortable fit whether you're wearing them all day or perching them on your head between errands.
All BELLA frames include 100% UVA and UVB protection with scratch-resistant lenses, and they're prescription-ready—any of these frames can be fitted with your Rx lenses, including options for polarization, photochromic technology, or blue light filtering. The premium CR-39 lenses deliver crisp, true-color clarity, and select variants feature polarized lenses that cut glare on water, pavement, and snow.
Why Customers Love the BELLA
Across hundreds of verified reviews, the BELLA consistently earns praise as a daily driver. Customers love how the oversized fit provides excellent sun coverage without feeling heavy or sliding down, and the quality rivals designer brands at a fraction of the cost. The versatile square shape works equally well with casual weekend looks and dressier outfits, and the variety of colorways means there's a BELLA for every style.
"The Bella is my go to for everyday looks. They match with every outfit, dark enough to cover my eyes if I'm not wearing any makeup but not too dark that I find it difficult to see." — Zappos reviewer
Every pair of Diff sunglasses sold helps provide the gift of sight to someone in need—to date, the brand has helped over 4.5 million people worldwide through eye exams, glasses, and vision care. When you choose the BELLA, you're not just investing in quality eyewear; you're supporting a brand that gives back with every purchase.
Each pair includes a protective travel case and cleaning cloth. Frame measurements: 54mm lens width, 19mm bridge, 142mm temple length.

Frequently Asked Questions
Are Diff BELLA sunglasses prescription-ready?
Yes, the Diff BELLA sunglasses are fully prescription-ready. Any BELLA frame can be fitted with prescription lenses by your local optician or through Diff's online prescription service. You can add single-vision, progressive, polarized, photochromic, or blue light filtering lenses to customize them for your vision needs.
What face shapes do the Diff BELLA sunglasses flatter?
The BELLA's oversized square shape flatters a wide range of face shapes, particularly oval, heart, and round faces. The large square frame (54mm lens width, 141mm frame width) adds structure and balance, while the softly rounded corners prevent the look from feeling too angular. Customers with various face shapes report the BELLA fits comfortably and looks flattering.
Do Diff BELLA sunglasses have UV protection?
Yes, all Diff BELLA sunglasses provide 100% UVA and UVB protection (UV400) with scratch-resistant lenses. This blocks harmful ultraviolet rays that can contribute to cataracts, macular degeneration, and other eye damage. Select BELLA variants also feature polarized lenses for additional glare reduction.
Are the BELLA sunglasses polarized?
Polarization depends on the specific BELLA variant you choose. Some colorways come with polarized lenses as standard (reducing glare from water, pavement, and snow), while others feature non-polarized UV protection lenses. Check the product specifications for your chosen color, or add polarized prescription lenses when customizing your frames.
How do Diff BELLA sunglasses compare to other oversized square frames?
The BELLA stands out for its combination of quality construction (hand-cut acetate and stainless steel), accessible pricing ($85-95), and the brand's charitable mission. Customers consistently note the quality feels comparable to designer brands like Michael Kors or Kate Spade but at a lower price point, and every purchase helps provide vision care to someone in need through Diff's partnership with Vision to Learn.
What's included with Diff BELLA sunglasses?
Each pair of BELLA sunglasses includes a protective travel case and a microfiber cleaning cloth. The frames are made from hand-cut acetate with stainless steel temples, premium scratch-resistant CR-39 lenses, and integrated nose pads for a comfortable, secure fit. Frame dimensions are 54mm lens width, 19mm bridge, and 142mm temple length.

Diff BELLA vs. Michael Kors Isle Of Palms vs. Kate Spade Jerri
If you're shopping for oversized square sunglasses in the $85-95 range, you're likely comparing the Diff BELLA against designer alternatives like the Michael Kors Isle Of Palms 2098U and Kate Spade Jerri. All three offer quality acetate construction, prescription-ready frames, and that coveted oversized square silhouette—but they serve slightly different needs.
The Michael Kors Isle Of Palms brings established designer cachet with signature MK logo detailing and a polished, sophisticated aesthetic. It's an excellent choice if you want recognizable brand prestige and a frame that skews slightly more formal. However, at $68-94, it sits at a similar price point to the BELLA without the charitable giving component, and some customers find MK frames feel more "occasion-specific" than everyday versatile.
The Kate Spade Jerri ($87-92) offers playful, feminine design with Kate Spade's signature cheerful aesthetic—think bold colors and whimsical details. It's perfect for customers who love the brand's fun, optimistic vibe. The trade-off? Fewer color options than the BELLA's extensive range, and again, no buy-one-give-one mission.
Why choose the Diff BELLA? The BELLA wins on versatility and value-with-impact. You get designer-quality construction (hand-cut acetate, stainless steel temples, scratch-resistant lenses) at an accessible price, with the widest range of colorways to match your personal style—from classic tortoise to soft rose crystal. Most importantly, every BELLA purchase helps provide vision care to someone in need through Diff's partnership with Vision to Learn (4.5+ million people helped to date). Customer reviews consistently praise the BELLA as a daily-wear workhorse that looks great, feels comfortable, and makes a difference. If you want oversized square frames that do it all without the designer markup, the BELLA delivers.
