Reducing the Stress of Digital Life

Computer Vision Syndrome is nothing new. It’s been around since the 1970s, but today’s situation is a whole new virtual ballgame.

Fortunately, we have an ever-expanding selection of digital spectacle and contact lenses that can be used to bolster the oculomotor system.

As Bob Dylan said, ‘The times they are a-changin’. Indeed, they are and indeed they have. A few years after Bob penned these words, Alvin Toffler, author of the best seller Future Shock (1970) stated that “Future shock is the shattering stress and disorientation that we induce in individuals by subjecting them to too much change in too short a time”.

Fast forward 50 years and we see the effects of change pervading our lives.

If for example, you follow the various social platforms, you’ll note increasing discussions, questions, observations, anecdotes and evidence surrounding changes invoked by COVID-19 and the toll of repeated lockdowns – visually and otherwise.

COVID-19 sped up our reliance on digital devices for work and leisure. Anecdotal reports of an increase in myopia progression during the pandemic have now been scientifically validated1 and a new term ‘quarantine myopia’ has become part of the lexicon.

By asking the right questions you will soon find out that many people experience symptoms of asthenopia, but don’t mention it up front


The accommodative-convergence system can only take so much abuse before it runs into trouble. Potential early warning signs can manifest as symptoms of blurred vision, diplopia, headaches, dry or watery eyes, neck pain and at times, migraines and nausea. If not dealt with effectively, these issues can develop into debilitating problems and structural change, as well as under performance at school, work and more.

Whether the patient sitting in front of you is a primary school child, a teen student or adult, all can benefit from the advances in, and advantages of, so called digital/ computer lenses.

The old adage ‘prevention is better than cure’ applies here more than ever, and is no more clearly seen than in the rapidly evolving arena of myopia control/ prevention. Today we can include lenses developed, tested and marketed specifically for myopia control in the gamut of digital lenses. We will however, focus on specific digital designs in this edition.

Digital lenses can be seen as bolstering the oculomotor system, which ideally prevents symptoms and/or allows people to enjoy visual activities for longer periods of time. That doesn’t mean we should extend our cycles of concentrated near vision. Whether a person is reading from a book, Kindle or tablet; gaming, using a smartphone, engaging in tasks with fine detail, or working at a computer, regular breaks – including gazing at distant objects – are part of our visual and general hygiene. Walking around, getting some water or a meal are better than slugging back the energy drinks and eating take-out fast food at your workstation 24/7.


When prescribing digital lenses, it’s essential that we take individual working distance, posture and the type of near visual tasks into consideration.

These vary considerably between users and the type of device used; for example, a younger person may hold their smartphone at 20cm, whereas a presbyopic adult may hold their phone or tablet at 30 to 60cm. These different user behaviours have created challenges for lens designers and dispensers alike, as Nicola Peaper, National Sales and Professional Services Manager at Rodenstock Australia, explains. “When computer lenses were first introduced, they tended to be intermediate/near lenses with two larger working areas of specific powers and a short corridor tying them together. This was fine for last century working conditions where one screen and near paperwork were the main office tasks. Now we have multiple screens at different distances in different gaze directions, including smart phones at distances closer than 40cm that need to be considered. The challenge is developing a lens that gives enough width of vision at many different distances, while maintaining the ‘correct’ ergonomic head position.”

In practise we see that someone working on a large screen or multiple displays may have their screen positioned as far as 80cm, while still needing to see other things in the 20cm to 80cm range and beyond. Such things are also influenced by body type; those with shorter arms usually hold things closer than people with longer arms.

When prescribing and dispensing Ms Peaper advises, “When calculating the power needed to see a screen, it is vital to remember how much the patient’s residual accommodation is used to focus at that distance. It is not a simple one formula calculation. For multiple screens side-byside and stacked vertically, a ‘corridor’ lens design will not always work and a ‘boost’ lens may be indicated. Consider calculating the power for the middle of the furthest screen and use the boost for closer visual tasks.”


Engage your patients, discuss the issues and address specific needs. By asking the right questions you will soon find out that many people experience symptoms of asthenopia, but don’t mention it up front. Some people assume that headaches and sore, dry eyes are normal. For those who have not worn spectacles before, alleviating them of these symptoms by prescribing digital lenses will surely result in a patient for life and plenty of positive referrals. For existing spectacle wearers, doing so can pave the way for prescribing multiple pairs of spectacles, targeted for specific uses.

In addition to spectacle lenses, there are now a variety of multifocal contact lenses in traditional designs as well as Extended Depth of Focus (EDOF) varieties; some of which are marketed specifically for digital eye strain. Essentially, any lens that reduces accommodative-convergence demand can be a winner, be it a spectacle or contact lens. William Tse, General Manager of SEED Contact Lens ANZ, offered this advice when it comes to contact lenses. “Consider using a low add EDOF design, which can be useful for those who suffer from accommodative stress due to excessive use of digital devices, mostly involving close-up reading. Relaxing the vergence system can improve reading speed and reduce issues of refocusing from near to far, among other things.”

Toffler also said that “Change is not merely necessary to life – it is life”. Embrace change, prescribe digital lenses and do what you can to make people’s lives easier. Check out the following fantastic options available from our partners and suppliers.
