Are you one of those savvy Cyber Monday shoppers, currently relaxing by the keyboard or touchscreen checking out today’s best deals? You’ve bypassed the stress experienced by the Black Friday shoppers who braved the crowds, but did you know Cyber Monday can come with its own drawbacks? Online shoppers spending as little as two hours in front of a screen are susceptible to digital eye strain from blue light exposure.


What is Blue Light?

Whether you shop via smartphone, tablet, or computer, your eyes are taking in blue light. And we’re not talking about banner ads for specials at Kmart. Blue light is a high-energy light source emitted by digital devices and computer screens. Exposure to blue light can result in sore, tired, irritated eyes in as little as two hours of screen time.

You’ve hit the 2-hour threshold before you know it 

You don’t have to be a shopaholic to hit the two-hour mark. Especially when you factor in shopping, reading reviews, comparing deals, and then finding a new retailer because the one you returned to is already sold out of the item you wanted. Fortunately, there are a number of ways to defend your eyes on Cyber Monday, regardless of how long it takes you to find this season’s must-have gift. And unlike prepping for the carnage at your local outlets or mega store come 12:01 a.m. Black Friday, none of them require armor or a helmet.

5 tips for reducing blue light while racking up deals

Here are five things you can do to reduce your blue light exposure and combat digital eye strain this Cyber Monday (and any other day of the week for that matter):

  1. Follow the 20/20/20 rule Every 20 minutes, take a 20 second break, and focus your eyes on something at least 20 feet away. If you’re an avid shopper, you may want to plot your breaks ahead of time to ensure you don’t miss that flash sale on this year’s ugliest Christmas ties.
  2. Turn down the brightness on your screen – The obvious choices are often the overlooked ones. Give your eyes a break before you even get started by dimming your screen.
  3. Turn up the font size on the screen – Increasing your font size means less squinting to read those lengthy, fine-print return policies. Also, smaller font generally results in holding your device closer to your eyes. And the closer your eyes are to the source, the greater the blue light intensity.
  4. Get an app -The blue light issue hasn’t gone unnoticed by app developers. Visit your preferred app store and download an application that cuts the amount of blue light coming from your screen. There are several good ones available for Apple and Android.
  5. Wear blue-light-reducing glasses – If you’ve got them, wear them. If you don’t, ask your eye doctor about TechShield Blue, an advanced coating that’s applied to your lenses. It reduces your exposure to specific blue light wavelengths that contribute to digital eye strain. So even if you drop while you shop, your eyes will feel better when you get back up. It’s also virtually clear, so when you do step away from the computer and rejoin the rest of the world, you’ll feel as great about the way you look, as you do about those amazing deals you just scored.

There you go. Five easy ways to give your eyes a break from blue light this Cyber Monday.

    A recent study indicated that LED light bulbs are bad for the eyes. What types of light bulbs foster optimal eyesight and provide the least strain?
