How To Protect Your Eyes From Too Much Screen Time

When asked at a recent eye exam how many hours a day I spend in front of a screen I was almost tempted to lie. Most of us spend far too long staring at screens (which includes computers, phones and tablets) but as a blogger my whole life is in front of a screen. But I’m glad I didn’t fudge my answer because there’s an amazing new lens on the market designed to protect our eyes from the harmful blue light emitted from screens.
Eyezen lenses reduce the impact of blue light on our eyes and prevent us suffering eyestrain and everything that comes with that – tiredness, headaches and in the long term, damaged eyes.  Optometrist and owner of Parker & Co Eyewear in Auckland’s Newmarket Geoff Parker says: “The single best thing about Eyezen is we finally have a lens that is responding to our changing lifestyles. Substantial increases in screen hours and exposure to blue light have simply never been seen before and Eyezen protects our eyes from the potentially harmful effects of long term blue light exposure. He says Eyezen lenses are for everyone too. Not only those of us who currently wear glasses. He says: “I recommend this lens to high volume screen users between the ages of mid-late teens through to 40 sometings who are showing signs of eye tiredness and reduced concentration. The Eyezen lenses allow the eyes to relax more when looking at screens which allows more comfortable and productive vision.” Winning!

  • According to Geoff Parker the single best thing we can do to look after our eyes is have them examined on a regular (two yearly basis) to assess our vision and eye health. “Sadly unless you had glasses from an early age my general experience is that people never give their eyes a thought and simply take them for granted.”
  • Geoff says the eye has a number of small muscles that allow it to focus and these muscles were never designed to focus for extended periods of time without rest. As a result long screen usage causes eye fatigue (sore, tired eyes often with reduction in concentration) which in turn causes blurry vision and often dry eyes. The best rule of thumb is to rest your eyes for between 5-10 mins per hour of computer use. When using your phone or tablet intermittently look up at something in the distance, make sure it is clear and then refocus on your screen (in order to keep your muscles flexible).
  • The peeps at Eyezen suggest making it easier on your eyes by dimming the surrounding lights in the room so they don’t compete with screen lights .
  • Be sure to keep all of your screens free of dirt to minimise eye strain from excessive smudges.
  • Enlarge the size of text to help your eyes focus and see more comfortably. 
  • Another way to protect your eyes against too much screen time is to start blinking more. Okay it does sound a little silly but blinking helps to keep your eyes lubricated and while it won’t prevent blue light damage it will help to reduce eye strain.
  • Even though blue light is nothing new, the real issue is the amount of blue light exposure we are getting each day through our digital devices. With this exposure increasing over time, we are actually causing permanent damage to our eyes. But unlike digital eye strain, the effects of blue light are cumulative and can lead to eye diseases like macular degeneration. So this is why Geoff suggests getting a regular eye test even if you don’t currently wear glasses.
