Eyes Wide Shut (Unless You're Blinking More Because of Dry Eyes)

June 6 was National Eye Care Day in China, which – yes, is a real thing – and like all state-approved themed days, it came with a flurry of lectures, screenings, and enough pamphlets to wallpaper a clinic. The theme? Your eyeballs. Specifically: dry eyes, myopia, and a few shiny new tools in the optometry toolbox.

If your eyes feel like sandpaper after scrolling Douyin or clicking through PDFs for hours, congratulations – you're part of the global dry eye epidemic. It's not just you. Between office screens, phone screens, and every LED billboard on Huaihai Rd, we've engineered an environment where blinking is optional and eye moisture is endangered. Most people grab eye drops and call it a day.

But at Longhua Hospital – Shanghai's flagship Traditional Chinese Medicine (TCM) center – Dr Zhang Yuyan says drops are just the Band-Aid. "Dry eye isn't a new condition," she explains. "In TCM, we've got centuries of theory and treatment behind it." Their approach combines Western techniques with traditional Chinese remedies, aiming to treat not just the dryness, but why your eyes are drying out in the first place. (Spoiler: It's not just the screens.)

Herbs, Heat, and Eyeball Engineering

In TCM-speak, dry eye isn't just a hydration issue – it's a whole-body imbalance. Specifically, a lack of qi (think: your body's energy currency) and weakened liver and kidney function, which, in this context, aren't just about detoxing or chugging cranberry juice. They're more like internal regulators in the TCM ecosystem. The fix? Herbs. Lots of them.

Longhua Hospital's approach sounds a bit like something out of a wellness day spa crossed with a sci-fi lab: misting your eyeballs with a vaporized herbal cocktail of chrysanthemum, mint, mulberry leaf, and a lesser-known player called Spanish needles. The herbs are blasted into micro-particles using ultrasound technology – yes, that same kind of ultrasonic buzz used to clean your fancy jewelry – then delivered straight to your ocular surface.

While your eyes are getting the spa treatment, tiny needles are gently poked into acupoints around your face to stimulate blood flow and qi. The goal? Wake up the tear glands. Especially helpful, says Dr Zhang, for folks suffering from Sjögren's syndrome, a tricky autoimmune condition where your immune system attacks your tear and saliva glands. (Translation: super dry everything.)

If your issue is blocked meibomian glands – those tiny oil-producing glands along your eyelids that keep tears from evaporating too fast – there's a tool for that, too. Longhua's engineers whipped up a special clamp (picture a mini-jaw of life, but for eyelids) that helps clear the gunk. Add in a little laser therapy, some gland massage, and hot compresses soaked in herbal packs, and voilà: your eye spa is complete.

Myopia Rates in Children Declining

Here's some rare good news: the rate of myopia (that's nearsightedness, for those of us who've never squinted at a blackboard) among Shanghai kids aged 6 to 18 has actually gone down – by 1.5 percentage points since 2013. That's not earth-shattering, but in a city where screen time often outpaces sleep, we'll take the win.

Behind the drop is a slate of low-key but important public health moves. The Shanghai Eye Disease Prevention and Treatment Center has rolled out a new monitoring and intervention program targeting younger children – those who are just starting to become nearsighted or haven't tipped over that edge yet. The plan? Screen twice a year and jump in with tech-based interventions early, before little Kevin needs Coke-bottle lenses by Grade 3.

The push is timely. Thanks to screen addiction, less outdoor play, and TikTok babysitters, kids are developing myopia earlier than ever. That's not just a glasses problem – it's a fast track to high myopia, which ups the risk of serious complications like retinal detachment (when the retina peels off like cheap wallpaper) and maculopathy (damage to the part of the eye responsible for sharp vision). Both can lead to vision loss or even blindness, and it's becoming a top concern in Shanghai's aging population.

AI, Eyeballs and the DIY Clinic Revolution

Meanwhile, Shanghai's vision game is getting a tech upgrade. The city just dropped an AI-powered community eye health service network, which sounds like a buzzword salad but actually makes a lot of sense. Here's the deal: walk into one of 60 community health centers across the city, stick your face into a smart machine, and within 20 seconds, a built-in AI gives you a basic eye screening.

If it flags something funky, a general physician steps in to interpret the results and – if needed – recommends follow-ups, referrals, or treatment. It's eye care in the age of convenience. No waiting rooms. No trip to a hospital on the other side of town. Just you, a machine, and maybe a curious ayi watching.

This is all part of a bigger play by the Vision Intelligent Management Center (VIMC), a pilot program dreamed up by the Shanghai Eye Disease Prevention and Treatment Center. Think grassroots healthcare with a tech backbone. The long game? Expand this to the entire Yangtze River Delta and even countries in the Belt and Road Initiative. That's soft power, with eye drops.

They're also training neighborhood doctors, setting up long-distance consultations for tricky cases, and adding a new self-service feature to the city's official Health Cloud platform – Jiankangyun 健康云 – where you can book screenings, get eye care tips and manage your vision profile without ever leaving your sofa.

High-Tech Lenses and AI at the Eyeball Frontlines

Shanghai's eye health overlords aren't just tinkering with community clinics – they're also diving headfirst into clinical innovation. The city's eye disease center is teaming up with local pharmaceutical companies on research into orthokeratology (a mouthful, yes – but think of it as special contact lenses you wear overnight to gently reshape your cornea while you sleep) and cutting-edge optical lenses that do more than just correct vision.

The idea is to close the gap between fancy medical tech and what people actually need at street level – less "one day this could help" and more "here's a better way to fix blurry vision right now."

Dr Zou Haidong, who heads the center, says AI is also stepping in to fill a more basic need: the shortage of medical staff in rural and neighborhood clinics. Their plan? Use technology to scale expertise – rolling out dry eye treatments and vision training (structured eye exercises to strengthen focus and coordination) across grassroots medical facilities throughout the Yangtze River Delta.

The end goal is to flatten the quality gap between big city hospitals and the countryside. "Same-quality service" is the phrase Dr Zou uses. Because in a place as massive – and myopia-prone – as China, the real innovation isn't always the tool. It's making sure it gets into everyone's hands.

Shanghai Medical Breakthrough - Big News in Tiny Molecules: A Cancer Drug First for China

While everyone else was busy watching their screens and forgetting to blink, Dr Lu Shun over at Shanghai Chest Hospital was helping make medical history. Together with Hengrui Pharmaceuticals, he co-developed trastuzumab rezetecan – a name that rolls off the tongue like a minor Transformer – but more importantly, it's China's first homegrown antibody-drug conjugate, or ADC.

(For non-oncologists: an ADC is basically a guided missile for cancer cells – an antibody targets specific markers on a tumor, then delivers a microscopic payload of chemotherapy straight to it. Precision killing, minimal collateral damage.)

This specific ADC targets a nasty subtype of non-small cell lung cancer (NSCLC) that's tied to a gene mutation called HER2. For people whose cancer didn't respond to regular treatment, this drug offered a lifeline – 74.5% of patients in trials responded positively after a 14-month follow-up. That's a top-tier number, even on the global stage.

It's a game-changer for the nearly 800,000 people in China diagnosed with lung cancer every year. The majority – around 70 percent – don't catch it until it's too late for surgery. For them, treatment usually means chemo, and hope gets smaller with every scan. This new drug? It's a rare beam of light in an otherwise pretty bleak tunnel.

Even more? It's a marker that China's not just following global biotech trends anymore. It's starting to lead them.

Health Byte Tips

Vapes Are (Sort Of) Vanishing, But the Smoke Hasn't Cleared

Fudan's researchers are calling for tougher enforcement and better public education around vaping – because right now, the rules are there, but the smoke (and loopholes) haven't really cleared.

It gets worse: only 83% of shops have the legally required "no sales to minors" warning. And fewer than 1 in 5 include any kind of health risk label about vaping – which, for the record, is linked to lung damage, nicotine addiction, and not being able to climb stairs without wheezing by age 35.

China rolled out its national e-cigarette management rules three years ago, banning flavored vapes and shutting down online sales. Great in theory. In reality? More than 90% of vape shops still quietly help customers order online, and one-third of them are still selling flavored products, just under the counter or with a wink.

But zoom in, and it's not quite the clean break it looks like.

According to a new survey from Fudan University's Health Communication Institute, the number of shops in Shanghai and Chengdu selling e-cigarettes–especially the fruity, candy-colored ones–has dropped noticeably. On paper, that's a win for public health.

Wait, Vaping is Bad For You?

Yes... Yes it is. To the surprise of many, who thought vaping was a safer alternative to smoking... there are indeed health detriments.

1. Lung Damage

Vaping has been linked to a condition called EVALI (e-cigarette or vaping use-associated lung injury). This can cause shortness of breath, coughing, chest pain, and in severe cases, hospitalization or death. Some people develop popcorn lung (bronchiolitis obliterans), a rare and serious lung disease tied to chemicals like diacetyl, used in some flavorings.

2. Nicotine Addiction

Most vapes contain nicotine, which is highly addictive, especially for teens and young adults. It affects brain development, attention, memory, and impulse control. A single vape pod (like a JUUL) can contain as much nicotine as a whole pack of cigarettes.

3. Heart and Blood Vessel Risks

Nicotine increases heart rate and blood pressure. Over time, it can contribute to cardiovascular disease, just like smoking. Vaping also causes inflammation in blood vessels, which is a known risk factor for heart attacks. If you're not familiar with how serious this is, check out the story of an expat living in Shanghai who had a heart attack in his 30's.

4. Unregulated Chemicals

E-cigarettes often contain unknown or unregulated chemicals – flavorings, solvents, and preservatives – some of which turn toxic when heated. These can damage lung tissue or irritate the respiratory system. Many of these compounds haven't been studied long-term, so the full effects are still unfolding.
