The Easytwist ET840 Eyeglasses are built for people who need frames that can keep up with real life. Made from a proprietary memory metal alloy called Trilaston, these full-rim rectangular frames flex, twist, and bend without losing their shape. Drop them, sit on them, or fall asleep wearing them—the ET840 bounces back.
Unlike standard nickel-titanium frames that gradually lose flexibility over time, Easytwist’s Trilaston alloy is a nickel-free, copper-based metal enriched with aluminum. This material delivers true shape memory: the frames return to their original form even after being bent or crushed. The ET840 features a patented TurboFlex hinge system that allows the temples to rotate 360 degrees, absorbing stress that would snap conventional frames. This isn’t marketing—it’s engineering designed to resist the kind of everyday abuse that sends most glasses to the repair shop.
The stainless steel construction is corrosion-resistant and hypoallergenic, making these frames safe for sensitive skin. The slim temples widen slightly at the tips and include coated temple ends for stability and comfort behind the ears. At 54mm lens width, 18mm bridge, and 140mm temple length, the ET840 offers a medium fit suited for most adult faces.
These frames are fully compatible with prescription lenses, including single-vision, progressive, and bifocal options. The rectangular lens shape provides ample room for multifocal prescriptions, and the full-rim design holds lenses securely. Available in three finishes—Satin Dark Brown, Shiny Very Dark Grey, and Matt Black—the ET840 pairs professional style with serious durability.
Customers report impressive longevity. Real-world reviews mention frames lasting 5, 8, even 10+ years of daily wear. One reviewer noted they’re “hard on glasses” but bought four more pairs after a decade of use. Another called them simply “the best frames that you can have.” For anyone tired of replacing bent or broken frames every year or two, the ET840 offers a different value proposition: buy once, wear for years.
