What are blue light rays?

Let’s go through that one page in science, don’t worry it’s pretty simple. The sunlight is made up of different colours that form a spectrum. Each colour constituting the spectrum has its own wavelength and therefore, different degrees of energy. Blue light is also one of them, the shortest wavelength with the highest amount of energy.

The blue light is a visible ray in the colour blue that releases the highest amount of energy.

Sources of blue light rays

Blue light rays aren’t just emitted from the sunlight. It’s found everywhere around us, especially due to technology advancement. Blue light rays are constantly emitted from everyday objects, such as LED lights, Flat-screen televisions, computer screen, tablet screen, smartphones and other digital devices.

Why is blue light emission harmful?

No matter whether you wear varifocal glasses or readers, everyone seems to get a blue light coating on it. Why is blue light rays emission so concerning? Well, blue light rays are extremely detrimental to our eyes and overall health. If you spend prolonged hours staring at your smartphone or use a computer screen, even for your work, you are bound to experience numerous visual discomfort.

Multiple strides have suggested the negative and long-term impacts of the screen. The impact of blue light from digital devices is more severe than the sunlight due to the close proximity of the screen with our eyes.

Blue light rays can penetrate all the way to the retina and can damage the light-sensitive cells in them. Which leads to permanent eye damage. If blue light rays absorption in the eyes isn’t ceased at an early stage, it causes an onset of age-related macular degeneration and cataract, ultimately causing permanent vision loss.

The blue light wasn’t always harmful, but with our growing digital dependency and computer vision syndrome, it’s a growing concern.

What is computer vision syndrome?

Computer vision syndrome is an umbrella term for vision problems and discomfort caused by digital devices, such as smartphone, PC or tablets. Blue light rays emitted from the screen constantly penetrate the eye, causing numerous eye problems. The symptoms of computer vision syndrome are blurry vision, headache, eye-fatigue, dry-eyes, itchiness, redness or burning sensation. Often, blue light rays penetration turns so severe that it disrupts your sleeping cycle. Blue light rays suppress the release of the sleep-inducing hormone, melatonin if you are using screens at night. With no hormone release, your brain is manipulated into thinking it’s daylight so you stay alert, active and awake.

What are blue light glasses?

Blue light glasses are specially created to reflect incoming high-energy blue light rays from all sources, mostly from digital devices. Glasses with blue light coating help to tone down eye problems and improve your sleeping habit. Since digital devices are deeply integrated into our lives, blue light glasses help to properly adapt to it.
