The McAllister MC4512 Eyeglasses deliver a modern take on the classic rectangle frame, combining contemporary style with eco-conscious materials. This modified rectangular frame is constructed from plant-based resin derived from castor bean oil—a renewable, highly resilient alternative to standard petroleum-based plastics. The result is a lightweight, durable frame that’s easier on the planet without compromising on quality or comfort.
Available in three gradient colorations—Tortoise Gradient, Pink Gradient, and Grey Gradient—the MC4512 features a two-tone design that adds visual depth and sophistication. The full-rim construction provides excellent durability and works well with a wide range of prescription strengths, including single vision, progressive, and bifocal lenses. With a 54mm lens width, 17mm bridge, and 140mm temple length, these frames offer a large fit suitable for most adults.
McAllister’s plant-based resin frames contain at least 45% bio-based material sourced from castor beans. Castor plants thrive in harsh, arid conditions where few other crops can grow, making them a sustainable choice that doesn’t compete with food production. The oil is pressed from the beans, formed into pellets, then melted and injected into frames—creating eyewear that’s strong, lightweight, and comfortable for all-day wear. This material reduces reliance on fossil fuels while delivering the same performance you’d expect from traditional plastics.
Rectangle frames like the MC4512 are particularly flattering on round and oval face shapes. The straight lines and horizontal emphasis add structure and contrast to softer facial features, creating a balanced, refined look. The unisex design works equally well for men and women, and the gradient finish adds a touch of personality without being overly bold. Whether you need them for work, daily wear, or as a versatile backup pair, these frames transition easily between settings.
The MC4512 is prescription-ready and ships with demo lenses that can be replaced by your optician or through our lens customization options. McAllister is part of Altair Eyewear, a division of VSP Global, and honors the legacy of John McAllister, one of the founders of American optometry. Each pair comes with an authentic designer case.
