Digital Eye Strain? You Might Need Blue Light Glasses
With the world turning to electronic devices to carry on with everyday activities, it’s no wonder most of us feel dry eyes, watery eyes, eye strain, blurred vision, and headaches. Nearly 70% of American adults are experiencing a form of digital eye strain due to prolonged use of electronic devices, a syndrome called Computer Vision Syndrome (CVS).

If you are experiencing any of these symptoms it is important to have a complete eye exam. Believe it or not, even small inaccuracies in your prescription lenses can contribute to CVS. Updating your current eyeglass prescription is key in reducing symptoms but an exam is also important in ruling out additional vision problems.  

 

If after you have done the necessary steps to prevent CVS but are still experiencing symptoms, you should consider purchasing customized blue light computer glasses. These specially-crafted lenses that are said to block or filter out the blue light given off from digital screens. They are prescribed specifically to reduce eye strain, prevent eye disease and can even improve sleep habits! 

Blue light from LED devices like your smartphone or laptop prevents the body’s production of sleep-inducing melatonin. A study done by the University of Houston found that participants wearing the glasses showed about a 58% increase in their nighttime melatonin levels.  

If you’re not sure if blue light glasses are for you, there are other steps you can take to help reduce symptoms of CVS. The American Academy of Ophthalmology, the Vision Council, and other vision-related organizations recommend the following: 

 

  • Adopting the 20-20-20 rule which means that every 20 minutes you look at an object at least 20 feet away for 20 seconds. 
  • Adjust your seat or the position of your computer, so your eyes are about 25 inches from the screen and position the screen so you’re gazing slightly downward. 
  • Use a matte screen filter to reduce glare. 
  • Use artificial tears when your eyes feel dry. 
  • Pay attention to the lighting in the room. You might try increasing your screen contrast. 
  • If you wear contact lenses, give your eyes a break by wearing glasses now and then.
