Screening for screen-related harm

In this increasingly digital world, the time we spend per day directing our vision at a screen is increasing no matter how old you are – phones, TV, computers. This might shock you, but the average Australian now spends at least 10 hours a day staring at some form of digital device. There is no denying that this can be potentially damaging to your eyes.

Headaches, tired eyes or neck and shoulder pain are directly linked to screen-related overuse. This wear and tear is known as digital eye strain and the damaging light source is known as blue light.  

While blue light comes directly from the sun, it also is emitted from all manners of screens including smartphones, tablets, personal computers and televisions, as well as from artificial light sources such as LEDs and fluorescents.

Too much exposure to blue light can cause both immediate discomfort and long-term harm. When it penetrates the eye deeply, it restricts the amount of melatonin released in the brain, which is the hormone essential to sleep. If this happens on a regular basis, your circadian rhythm goes out of sync and your sleep-wake cycle is disrupted. A disrupted sleep-wake cycle can have a tremendous effect on your mental processes, mood and overall health.

Our optometrists have adopted the latest and most comprehensive lens technology to help protect your eyes from blue light and minimise all related damage. Our Smart Blue Filter lenses reduce both digital eye strain and the possibility of a disrupted sleep-wake cycle, without altering or distorting the colours you see. These lenses can be fitted to all styles of prescription glasses and can turn a pair of non-prescription glasses into “screen glasses” – a growing, sensible trend amongst adults and children alike.

Again, the key is to detect any abnormalities as soon as possible so, make sure you book an appointment with us as soon as you can because your ongoing eye health is too important to ignore.
