The McAllister MC4516 eyeglasses bring together American heritage and modern sustainability in an oversized rectangle frame that works for any face shape. These unisex prescription-ready frames feature a modified rectangle shape with geometric detailing—notice the linear cutdown on the outer corners that creates a bold, architectural look.
The MC4516 is constructed from plant-based resin derived from castor bean oil, a renewable alternative to petroleum-based plastics. This bio-based material makes up 45% of the frame, reducing environmental impact while delivering the same lightweight durability you’d expect from traditional acetate. The castor plant thrives in arid conditions where other crops can’t grow, making it a genuinely sustainable choice. The result is a frame that’s noticeably lighter on your face—perfect for all-day wear—without sacrificing strength or flexibility.
The MC4516 features a keyhole bridge that distributes weight evenly across the sides of your nose rather than pressing down on the bridge. This design reduces pressure points and prevents the red marks and discomfort that come with standard bridges. If you’ve struggled with glasses that pinch or slide, the keyhole design offers a secure, comfortable fit that stays put during active days. The bridge also adds a vintage-inspired detail that pairs well with both classic and contemporary wardrobes.
Available in three crystal finishes—Taupe, Olive, and Black—the MC4516 measures 57mm lens width, 17mm bridge, and 145mm temple length. These frames are prescription-ready and can be fitted with single-vision, progressive, or blue-light-blocking lenses. The full-rim design provides maximum lens stability and durability, making them a reliable everyday option whether you’re at work, running errands, or out with friends.
