The Easyclip EC421 eyeglasses combine prescription-ready frames with patented magnetic clip-on technology that transforms your glasses into sunglasses in seconds. Built by Aspex Eyewear, the originators of magnetic eyewear, these square acetate frames use high-powered neodymium magnets that deliver a bond ten times stronger than standard ferrous magnets—secure enough for daily wear, yet easy to attach or remove with one hand.
Instant Sun Protection Without the Hassle
The EC421 solves a problem prescription wearers know well: constantly swapping between glasses and sunglasses, or relying on transition lenses that won’t darken behind a windshield. The magnetic clip-on attaches flush to the front of the frame with no visible hardware, sitting close to your prescription lenses to maintain your exact field of vision. Remove it just as fast when you step indoors. Each frame includes a matching clip-on in your chosen color—brown and crystal marbled, blue and crystal blue marbled, or red and crystal white marbled—plus additional clip-ons are available separately.
The full-rim acetate construction is lightweight and durable, with a 52mm lens width, 15mm bridge, and 140mm temples (52-15-140). The square shape works well on oval and round faces, offering structure and definition. Decorative ribbed temple detailing adds a refined touch. These frames are prescription-ready and accept single-vision, progressive, and most lens types from your optician.
Why Magnetic Beats Transition Lenses
Transition lenses require UV light to activate, which means they stay clear inside your car—the windshield blocks the UV rays they need. Magnetic clip-ons work anywhere, anytime, regardless of UV exposure. You also get instant tint control instead of waiting for photochromic lenses to adjust, and you can choose polarized clip-ons for glare reduction while driving or on the water. The cost advantage is significant too: instead of paying for a second pair of prescription sunglasses, you’re adding sun protection to the frames you already own.
Easyclip’s magnetic system is designed for real life—no scratching your lenses with spring clips, no fumbling with two hands while you’re holding coffee or car keys. The magnets are embedded in the frame and clip-on, so there’s nothing to break or wear out. Replacement clip-ons are available if you want a different tint or if you lose one, and the frames carry a one-year manufacturer’s warranty. Whether you’re commuting, working outdoors, or just tired of juggling two pairs of glasses, the EC421 delivers the versatility you need without compromise.
