This pandemic has been a disaster for so many businesses — but some are actually thriving.
In that second group, count the manufacturers of blue light-blocking glasses.
Before the pandemic, many of us were already spending way too much time in front of screens — but now that time has multiplied, as our other options for entertainment have disappeared, and everything from work meetings to schooling has gone online.
Sales of blue light blockers have boomed, according to bizjournals.com.
The glasses, which are different from prescription computer glasses, are supposed to block or filter the blue light emitted from screens. They range in price from $10 at Target to $95 from upmarket suppliers.
Boosters say they benefit our sleep cycle and reduce eye strain and headaches. Some even say the glasses will ward off macular degeneration and eye cancer.
Hmm. I’m not sure about that.
Do we really need them? The Washington Post reports that ophthalmologists are skeptical. The American Academy of Ophthalmology doesn’t recommend special glasses for computer use, and they say there isn’t really any evidence showing blue light-blocking glasses help.
So what do they recommend?
Blink to keep your eyes moist, follow the 20-20-20 rule – when you’re using screens, look at an object at least 20 feet away for at least 20 seconds every 20 minutes – and limit your screen use before bedtime.
You know the drill.
