5 eye issues prevented by wearing bluelight lenses

Bluelight is one of the spectra of colours. It’s naturally occurring from the sun and is also emitted artificially from our digital devices and some lights, such as LED.

Today we reach for digital devices more than ever. Long hours of blue light exposure is thought to be harmful to your eyes, causing a condition called digital eye strain (also called computer eye strain or computer vision syndrome) and retinal damage.

Screen time seems to be all the time for some of us. It’s probably no surprise if you’re feeling the effects of eye strain, especially if you work in front of a computer screen all day.

65% of digital device users experience digital eye strain symptoms (Vision Council), and although eye strain can be uncomfortable and irritating, the good news is that it isn’t permanent or severe. Eye strain will disappear once you allow your eyes to rest or take precautions to protect our eyes, like wearing blue light lenses. The five eye issues that can be prevented by wearing blue light lenses include:

1. Tired eyes

Have you ever felt ready for bed around the end of the day, only to be wide awake by the time you get home? That’s because you are not tired, your eyes are. Tired eyes are a common symptom of digital eye strain when using a digital screen over a long period of time, like a working day.

2. Eye irritation

One of the most common symptoms of eye strain is eye irritation, which can decrease the sharpness of your vision and may be a result of reduced blinking. People who work on screens blink as third as often as usual and may not close their eyes fully while blinking, reports All About Vision. Blinking keeps your eyes moist, washes away debris and spreads nutrients across your eye. Without it, our eyes can quickly get irritated.

3. Blurred vision

You might not realise, but it’s actually harder to read from a screen due to the letters not being as crisp or sharp, the glare caused by the screen and the reflections on the glass all make viewing more difficult. Poor posture, bad lighting, viewing distance, and screen resolution also worsen these symptoms. All of this can put extra pressure on your eyes, causing blurred vision. Blue light lenses can help to reduce the glare and relieve some of this pressure.

4. Headaches

It’s 3 p.m., and you start to feel a dull ache behind your eyes. You’ve noticed this happens most weekdays when you’re at work. Once you get home and rest on the couch, the headache vanishes. Sound familiar? If it is, your headaches could be caused by digital eye strain, and you’re not alone, headaches are one of the most common symptoms of digital eye strain.

5. Blindness

Studies suggest that continued exposure to blue light over time could lead to damaged retinal cells. The high-energy visible (HEV) artificial blue light has been observed to contribute to retinal cell damage in high doses, with smartphones causing the most damage as they are held closer to your face. Lenses that reduce glare, increase contrast and block blue light from the sun and digital devices, like blue light lenses, can all protect you from this cell damage.

Australians are spending more time in front of a screen than they are sleeping. According to a survey by Lonergan Research, almost a third of the day - 9.4 hours – is being spent exposed to blue light emitted from your computer, mobile phone and television screen. This screen time equates to an astonishing 143 days every year.
