Digital Lenses

Personalised eyewear, designed for your digital life.

As Australians, we love digital media.  We devote 50% of our waking hours interacting with digital media channels across multiple devices^. It has changed the way we shop, learn, work, relax and socialize.

The digital age means your eyes have never worked so hard.

Digital devices have evolved remarkably, yet our eyes have not evolved to adapt to the digital environment. 65% of users are likely to experience one or more symptoms of digital eye strain*. Innovative lenses are specifically designed for digital media use and help relax and protect your eyes while keeping them feeling fresh throughout the day.

 

What is Digital Eye Strain?

Digital eye strain is physical eye discomfort felt after two or more hours in front of a screen. The severity experienced varies depending on the individual, screen time and the type of digital devices used. Digital eye strain affects everyone, not just prescription glasses wearers.


Symptoms of digital eye strain can include one or more of the following:

  • Eye strain/fatigue
  • Headache
  • Blurred vision
  • Dry, burning, itchy or red eyes
  • Neck, shoulder or back pain

A 2016 study in the USA has shown that as many as 65% of digital device users experience digital eye strain symptoms.  Approximately 75% of people who use two or more devices simultaneously will be affected.*

Why does using digital devices cause eye strain?

There are a number of factors:

  1. Eyes are focusing more intensively and constantly to adjust to the frequent switching between devices at vary distances and size.  Increasingly smaller, pixelated characters and bright, glowing screens also contribute to the work load placed on the eyes focusing systems.
  2. Digital devices are back-lit and emit blue light that can cause strain and discomfort.  This blue light is also shown to disrupt sleeping patterns, especially with exposure within an hour of sleeping.
  3. We hold smartphones closer than any other device or reading material.  This has produced a new reading zone in ultra near vision, placing even greater demands on our eyes.
  4. Our blinking mechanism is interrupted, so we blink less while looking at digital screens.  A normal blinking rate is around 17 or more blinks a minute, but this reduces to 12 to 15 blinks which reduces tear production, making your eyes feel dry and uncomfortable.**
  5. In order to see our digital devices more easily, our posture has changed.  We tend to lean toward our screens or tilt our heads backwards which puts a strain on the neck and back.*

Innovative Digital Eyewear

Innovative lens technology has been developed for our digital world.  Addressing the symptoms of digital eye strain, these new lenses are designed to alleviate digital eye strain by eliminating glare, filtering out blue light and preventing vision fatigue.

The good news is that digital lens innovation caters to both prescription and non-prescription wearers affected by digital eye strain.

Digital lenses are designed to relax and protect your eyes by providing clear viewing at typical screen viewing distances, as well as reducing blur, brightness and glare.

If you currently wear prescription glasses, a dedicated computer or digital pair will not only combat eye strain, but likely deliver postural benefits for your back and neck as your focus will be optimised for close up and screen viewing.

Your Digital Vision

We will talk to you about the demands of digital device usage on your eyes and the type of work you do.  This is just one of the aspects we will discuss with you as part of our 360° comprehensive eye consultation. Knowing how much time you spend in front of digital devices, the type of screens and the setup of your digital environment will allow us to prescribe a tailored digital vision solution for you.

How to Reduce Digital Eye Strain

  • Remember to actively blink more to make up for a reduced blink rate.
  • Take a break from staring at your digital screen.
  • Use the 20-20-20 rule: for every 20 minutes in front of a digital device, take a 20 second break and look at objects 20 feet (6 metres) away
  • Adjust the display settings of your devices to a more yellow (less blue) colour balance or make use of your devices built in blue light filters if they have them.
  • Wear glasses designed for digital device use.
