There’s a moment in every cheater’s career when they think they’ve outsmarted the system—until they haven’t. That moment came for a student surnamed Lin at South China Agricultural University in Guangzhou on July 1st, when a supervisor spotted a telltale green glow emanating from his eyeglasses about ten minutes into an exam. What Lin had been wearing wasn’t just any pair of specs. It was a pair of Leqi Smart Glasses, a device released in September of last year that packs four major AI models—Deepseek, Tongyi Qianwen, Zhipu, and Doubao—into a frame barely distinguishable from regular eyewear.
The technology itself is genuinely clever. All Lin had to do was touch the frame near his temple to snap a photo of the exam question, and the glasses would feed the image through their integrated AI systems to generate answers—no voice command needed, no obvious gestures. The problem? He forgot to account for the one thing he couldn’t hide: physics. The LED that activates when taking a photo produces a green light visible through the lenses at certain angles. One small oversight. One caught cheater. One cautionary tale that apparently nobody’s taking seriously.
Because here’s where it gets worse. After Lin’s story went viral, other students didn’t learn a lesson—they learned a workaround. Social media filled with posts about how cheap sunshade stickers could easily conceal the green light. Vendors began advertising AI glasses rentals for as little as 200 yuan, complete with tutorials on switching the devices to silent and low-brightness modes. The cheating infrastructure didn’t collapse; it evolved. Similar incidents have already popped up in universities across Hubei, Henan, Beijing, and beyond, suggesting this isn’t an isolated incident but the beginning of a genuine problem.
The real wake-up call came from Lin Che, a product manager specializing in smart glasses, who pointed out that the arms race isn’t even close to being over. In the near future, these devices will be nearly indistinguishable from conventional eyeglasses—meaning exam supervisors, already described by at least one professor as almost completely unprepared, will face an impossible task. The only known defense so far? Checking thick-rimmed glasses more thoroughly. That’s not a strategy; that’s a band-aid on a dam that’s about to break.
What we’re watching isn’t just students finding a new way to cheat. It’s the collision between technology that’s advancing faster than institutions can adapt and a human impulse as old as testing itself: the desire to get ahead without doing the work. Universities are scrambling to react to a problem that will look quaint in five years. And students keep finding ways to make the game harder for everyone else—including themselves when they inevitably get caught.
