The wellness industry is worth billions — and a big chunk of that money comes from products that sound a lot more miraculous in a 30-second video than they turn out to be in real life.
Smart Senior Daily is working our way through some of the biggest ones, separating the science from the sales pitch. First, we tackled cold plunges and ice baths. Now, here's our second...
❌ Blue light blocking glasses
These things are everywhere – probably more prevalent than Berberine, mouth tape (for sleeping), and magnesium supplements (in every form imaginable).
Influencers swear by them. Opticians upsell them. Amazon is drowning in them, ranging from $15 to $300 a pair and selling nearly 17,000 a month. The blue light glasses market is projected to grow from $2.9 billion in 2024 to $5.8 billion by 2034.
There's just one problem. The science doesn't back it up.
🧑🔬 What the research actually shows
The most comprehensive look at blue light glasses to date came from a 2023 Cochrane review — and if you're not familiar with Cochrane, think of it as the Supreme Court of medical research.
Their researchers analyzed 17 randomized controlled trials involving 619 participants and landed on a conclusion that should give anyone who buys these specs some pause: the lenses showed no meaningful benefit for reducing eye strain compared to regular lenses. None. Zilch. Zero.
The country's leading organization of eye doctors, the American Academy of Ophthalmology, doesn't hold its tongue either. Their official position? Again, there is no scientific evidence that blue light from digital devices damages your eyes, and they explicitly tell patients to skip the glasses.
👁️ So what IS causing your eye strain?
Here's the twist your eyes will thank you for knowing. According to Brown University Health, the discomfort people feel after long hours of screen time isn't caused by blue light at all. Rather, it's caused by how we use our screens.
Specifically, we blink far less when staring at a screen, which dries out our eyes and fatigues the muscles that control focus. Blue light is essentially a red herring.
💡 The free fix that actually works
The American Academy of Ophthalmology recommends the 20-20-20 rule: every 20 minutes, shift your eyes to look at something at least 20 feet away for at least 20 seconds. That's long enough for your eye muscles to fully relax. Free. No Amazon order required.
Here's a fun kicker: a 2025 study found that 85% of long-term blue light glasses wearers reported improvement in their eye strain symptoms. Sounds like a win for the glasses — until you dig into what actually predicted that improvement. It wasn't the lenses. The strongest predictor was whether people followed the 20-20-20 rule. The glasses may have just been a reminder to take breaks.
💡 Bottom line for SSD readers
Eye strain from screens is real. Blue light causing it is not. Save your money, set a phone timer for every 20 minutes, and look out the window. Your eyes — and your wallet — will feel better.
