An expert has shared a serious warning about the dangers of blue light from digital devices and the impact of over using devices.

Studies across the world are finding that overuse of digital devices is causing an increase in eye health issues, headaches and migraines.

“We’ve done a study of people who regularly use digital devices, and the results are alarming,” Anand Keswani, founder of Optically.com.au has said.

“With a growing dependence on smartphones, many people are looking at their phones from as early as 5:30 am and staying on them well into the night.

“It’s well established that natural light is essential for our sleep cycles, and many respondents knew this, but startlingly few knew about the damage digital screens can cause to our eyes.”

Eye strain

Constantly looking at screens can cause eye strain. Symptoms of eye strain include dry eyes or a burning sensation, blurred or double vision, and irritation or itching.

“While these seem like mild symptoms, over a prolonged period of time they can severely impact people,” Anand Keswani added.

“And with a lot of these seemingly mild symptoms, they’re caused by serious issues including retinal damage and worsened macular degeneration.”

Cataracts are a rising concern

Studies also indicate that there may be a link between increased exposure to the blue light emitted by digital devices and an increase in cataract development. While there is a need for more research, this is a cause for concern.

“Eye specialists are reporting that some patients in their mid thirties are developing cataracts with the same level of cloudiness normally seen in patients over the age of 70,” Anand Keswani said.

With almost every profession happening in front of a screen these days, and younger generations growing up with screens throughout their lives, the problem is growing.

So how do we save our eyes from digital screen blue light?

“It’s actually not so hard to reduce the damage caused by digital screens,” Anand Keswani said.

“The easiest solution is to shop for digital blue coat lenses whenever you buy eyewear. These will prevent eye-strain, and while we can’t move away from digital devices, we can certainly keep our eyes protected.”

Anand’s business Optically.com.au offers these lenses as an affordable, stylish option to protect your eyes from strain.

Other than taking action to ensure your glasses are equipped to protect your eyes, Anand Keswani says, “make sure you give your eyes frequent rests, and make sure your screen is the same brightness as the rest of your surroundings. Take note of your posture while you are using digital devices and take regular breaks from devices.

“We are still yet to see the full extent of the damage digital devices do to our eyes, particularly for those who have been born using technology. Early indications are not good and do suggest that the increasing number of people presenting with cataracts in their thirties means the technology is causing harm.”

  • I have Mums giving babies their mobile phones with music playing with the screens facing them. One baby was only 12 months old when she was given the device in the supermarket. They were neighbours
    Some young children spend several hours per week with their devices that have digital (blue light) screens. They also have the heads down for length of time and it can cause neck problems which may not be evident for a few months.


  • We pay for the best eyewear with glasses – eyes are so precious.


  • To do away with technology is probably not possible. Moderation and protective measures is the key. Time to wake up and educate ourselves and our children !


  • i have never heard of a digital blue coat lens and for eye wear and my option did not recommend or offer it to me. should he have done?


  • Wow scary to think that something so seemingly harmless is causing cataracts!
