Flexon MELVILLE 600 vs. Other 600 Series Frames
Choosing between Flexon's 600 series eyeglasses often comes down to frame style and fit preferences—all models share the same revolutionary memory metal technology that bends and returns to shape, but they serve different aesthetic and comfort needs.
The Flexon MELVILLE 600 stands out in the lineup for its half-rim construction, which makes it the lightest option in the 600 series. The semi-rimless design shows more of your face and delivers a professional, understated look that works equally well in business settings and casual wear. The rectangular shape with straight temples suits round or oval faces particularly well, and the reduced frame weight makes it ideal for all-day comfort. Available in 53mm and 55mm lens widths, it's the best choice if you prioritize a minimalist aesthetic and lightweight feel.
The Flexon EINSTEIN 600 offers a full-rim rectangular design with bowed temples that accommodate wider head sizes more comfortably. While heavier than the MELVILLE 600 due to its full-rim construction, it provides maximum lens protection and works well for round or oval faces. The bowed temples are the key differentiator—if standard straight temples feel tight, the EINSTEIN 600's design distributes pressure more evenly. It's available in 52mm and 54mm lens widths and costs slightly more ($109.54–$116.31).
The Flexon NATHANIEL 600 features a full-rim geometric shape that adds a modern edge to the classic 600 series design. At $116.31, it's priced the same as the MELVILLE 600 but offers a bolder, more visible frame presence. The full-rim construction makes it heavier but also more protective of the lens edges. It's the right choice if you want a statement frame with the same memory metal durability.
The Flexon LARSEN 600 shares the MELVILLE 600's philosophy of minimal temple detailing and clean lines, but in a different frame shape. Starting at $109.54, it's a slightly more affordable option with the same memory metal in the bridge and temples. The main difference is the overall frame geometry—the LARSEN 600 offers a classic shape that may suit different face proportions.
Our recommendation: If you want the lightest, most minimalist frame in the 600 series with a professional half-rim look, the MELVILLE 600 is your best choice. Its semi-rimless construction cuts weight without sacrificing durability, and the rectangular shape is universally flattering for round and oval faces. If you need bowed temples for a wider fit, consider the EINSTEIN 600. If you prefer a bolder, full-rim presence, the NATHANIEL 600 delivers the same memory metal technology in a more visible package.
