We Live in a Device-Filled World! Are You Protecting Your Eyes?
Hand-held electronic devices are now an integral part of life and it can be hard to imagine a day without our laptop, tablet or Smartphone. The use of Smartphones, in particular, is on the rise and it's predicted that by 2020, 3 billion people across the globe will own one! Given that the average person spends about three hours a day on their Smartphone, it's reasonable to wonder what staring at a small, bright screen for so long and so often is doing to our eyes.
At Eyes Focused on You, we work to educate our patients about their health to enable them to take charge of it. With Smartphones being so pervasive, it's important to understand how they affect us. The fact is, our modern world is changing how we use our eyes. That's because we use Smartphones differently to books, magazines, and newspapers -- we tend to hold them closer to our faces. As well, the tiny screens on these devices force our eye muscles to contract continuously to focus on them properly. Both these things are unnatural for our eyes and can lead to eye strain and a sense that our eyes are aging prematurely, a phenomenon called Smartphone-induced presbyopia.
While eye strain -- or eye fatigue -- is not a disease of the eye and does not impact the eye's anatomy, it can cause considerable discomfort. Symptoms can include blurry vision as well as an unpleasant condition called dry eye in which eyes can become very dry, red and irritated. The effects of eye strain can even extend beyond the eye itself and trigger and exacerbate headaches.
Another problem with Smartphone usage is that their bright screens emit something called high-energy visible (HEV) blue light. Blue light, unlike the light from regular household light bulbs, for example, creates glare and flicker, which also contributes to eye strain. As well, blue light does a good job of mimicking daylight which tells the brain it should be awake and alert. This is not good if you're trying to get to sleep, so switch off your Smartphone well before bedtime!
So, what's the answer when the world has fallen in love with Smartphones, but it's not an entirely healthy relationship? Fortunately, some innovative new lenses designed especially for frequent users of Smartphones have been introduced by Nikon.
Nikon Smart Boost Single Vision Lenses
Nikon's Smart Boost lenses are designed to tackle the two main issues associated with Smartphones -- small print, and blue light glare and flicker. Their clever Smart Booster Technology, which works like a camera's optical zoom, helps you read small print more easily through a slight increase in power at the bottom of the lens which magnifies the text on the screen. As well, their smooth lens design lets your eyes move more naturally, providing relief for overworked eyes. Nikon's Smart Boost lenses also provide wearers with better colour contrast and protection from blue light. Their SeeCoat Blue Premium, an anti-reflective coating, actually absorbs eye-strain-causing blue light.
Clearly, it's important not to underestimate the impact of Smartphones given that well-rested eyes perform better, help keep headaches at bay and can help you live life at your best. If a Smartphone is an integral part of your life, the Nikon Smart Boost Lenses could be the answer. www.nikonlenswear.ca
