There seems to be a lot of hype these days about blue light blockers and lenses that protect your eyes from the effects of staring at screens. Let’s take a step back and discuss what this is all about.
What is blue light?
Blue light is one of the spectrums of colours that comes from the sun. Artificial blue light emanates from our digital devices and lights like LED. Many of us spend a lot of time on these digital devices and it’s increasing our risk of getting eye cancer.
Does blue light damage your eyes?
Recent evidence indicates that only extreme and sustained exposure to blue light causes damage to our eyes. Given many of us are now working from home and spending much of our time in front of a screen, it is wise to consider purchasing a pair of blue light glasses to protect your eyes.
Can you get eye strain from digital devices?
It’s probably no surprise that you work in front of a computer screen all day if your eyes are feeling dry or tired. Give them some TLC by:
- blinking often and staying hydrated,
- looking at objects at a distance every half hour to readjust your focus and give your eyes a break,
- taking regular screen breaks,
- turning down the brightness level on your screen at night, and
- getting an eye test done by a professional.
What can I do to reduce the effect of blue light?
Visit your local optometrist and ask about their blue light glasses range. They come in various colours and shapes, just like normal glasses. Prescription blue light glasses are available too.
Alternatively, you can purchase them online at a reasonable price. If you have private health cover you may also be able to get some money back, which is always welcome! Check with your health insurance company if you are eligible to claim back for blue light glasses.
It might just save your eyes!
