Anti-Blue Light Glasses: Why Everyone Needs One

2020 recorded the highest number of digital device viewing during the worldwide lockdown. People were forced to use virtual meeting platforms like Zoom, Google Meets, and Skype to engage in day-to-day office or schooling proceedings. More so, TV viewing, phone, and tablet usage were also at an all-time high to avoid the mind-numbing boredom that the lockdown caused.

As digital viewing grew, so did the eye problems that came with it. And so, the need for anti-blue light glasses aka blue light blocking lenses became more essential than ever before.

What is Blue Light?

Natural blue light comes from rays from the sun, and this is a natural source. It only provides benefits such as boosting alertness, improved memory, and it can also get you in a good mood.

Ever wonder why no one is ever sad on a sunny day.

Then there’s artificial blue light known as blue LED. It was created by Nobel Prize winners Asuchi Nakamura, Isamu Akasaki, and Hiroshi Amuno in 2014. They manufactured Blue LED and infused it with our everyday viewing devices like flat-screen TVs, computer monitors, smartphones, and tablets. It’s no denying that Blue LED is useful to the lives of millions and although the invention has done a great deal of good for humanity, it does have its negative side.

Computer Vision Syndrome (CVS)

Computer vision syndrome (CVS) is the side effect of prolonged viewing of a computer or digital device. Anyone who uses a computer continually has probably experienced one or more problems with their vision. Understand that viewing a computer screen differs from viewing printed pages because characters on screens aren’t very visible. So you have to strain your eyes or sit in a bad posture, just to get a better view of your screen. This causes you to make your eyes work way harder than they’re supposed to.

Causes of Computer Vision Syndrome

Glares and reflections on your digital screen make viewing difficult because you might have to sit in an improper position or view screens from an inappropriate distance (too far from a screen or too close).

Poor lighting in a room can cause you to strain your eyes. Also, existing uncorrected vision problems paired with blue LED are a dangerous combination that could lead to serious eye complications.

Symptoms of Computer Vision Syndrome

• Eye Strain: Constant and daily viewing of digital devices causes a strain on the eyes, and this could evolve into other problems that affect productivity and relaxation.
• Blurred Vision: Everyone needs clear eyesight at all times to avoid major and minor accidents like getting hit by a car while crossing the road or stubbing your toe.
• Dry eyes: Dry eyes are another CVS symptom because the eyes need to be lubricated to avoid itchiness and burning sensation in the eye, stringy mucus around the eyes, and redness.
• Headaches: This is a symptom you may not have known. Overexposure to blue LED puts a lot of pressure on the naked eye as well as the brain. Headaches from blue LEDs are a gateway to insomnia. Not having actual restful periods of sleep is a slippery slope to insomnia, and that’s not good for anyone.
• Neck and shoulder pain: This stems from bad sitting positions caused by having to position your seating in a way that allows you to view your screen better because your chair isn’t comfortable, the room has bad lighting, or the position of your device is badly set up.

Anti-Blue Light Glasses to the Rescue

Anti-blue light glasses protect the eyes from computer vision syndrome caused by overexposure to light emitted from the blue LED.

By combating these symptoms with an anti-blue light lens, you protect your eyes, and body from serious damage. The use of prescription, non-prescription, or reading glasses with anti-blue light lenses, will help you reduce the possibility of eye strains, headaches, and most also insomnia. People struggling with CVS will finally be able to fall asleep, stay asleep, and do it more restfully. It’s safe to say that if you’re reading this right now from whatever digital device, you might need to get yourself a pair of anti-blue light glasses.
