Blue light is, as the name implies, light with blue wavelengths. Sunlight is composed of visible and invisible ultraviolet light rays. Visible light rays come in red, orange, yellow, green, and blue colors, each of which has a different energy and wavelength.

Blue light is good. But like everything else that's good, too much of it can be harmful. Blue light boosts energy and alertness, helps with memory and cognitive function, and elevates mood. It's essential in chronobiology to regulate our body's natural wake and sleep cycle (circadian rhythm). 

As such, we naturally crave light during the day, and just as naturally, we need darkness to sleep. So, too much light at the wrong time can be harmful as it upsets our natural rhythm and can cause daytime fatigue.

Furthermore, blue light is the closest to invisible, ultraviolet light on the color spectrum, and, as we already know, ultraviolet light is dangerous. It can cause sunburn, which can lead to cancer. Ultraviolet rays can also burn our eyes, particularly the cornea, and lead to eye diseases, including age-related macular degeneration (AMD).

Blue Light is All Around Us

The sun is the primary source of blue light. As such, we're practically basking in it. It's also present in fluorescent lights, CFL (compact fluorescent light) bulbs, LED lights, flat-screen LED televisions, computer monitors, smartphones, and tablet screens.

In this digital age, it's practically everywhere as almost everything runs or is made by computers. And with the pandemic radically changing our lives as outside exposure is ill-advised. Virtual everything is encouraged, including working from home and virtual learning; we're clocking in even more screen time.

Blue light from screen exposure may be small compared to the amount of exposure from the sun, but with the amount of time we spend on digital devices, it still causes concern. There is also concern over its long-term effects because of the screens' proximity and the length of time spent looking at them.

According to a recent NEI-funded study, small children are significantly affected as their eyes absorb more blue light than adults from digital device screens, making them more susceptible to its ill effects.

Protect Your Eyes, Block Blue Light

Looking Through Blue Light Blocking Glasses: Reasons Why You Need One

With the growing concern with excessive blue light exposure, blocking it is a surefire way to protect our vision. Using blue light blocking glasses is then a must in eye care today. 

Livhò Blue Light Blocking Glasses can help protect your eyes in this digital age. They filter harmful blue-ray/UV 400 from frequent computer/tablet/phone use, thereby minimizing eye strain, headache, radiation, and migraine.

They are made of premium acetate and TR90 materials, making them synonymous with "high quality," capable of enduring particular physical impact, twisting, and extrusion without deforming, while remaining affordable.

They are stylish to boot, perfect for both men and women. Their square design is fashionable and unique, and their high-end and lightweight frames enhance the wearing experience.

The polycarbonate (anti-glare) blue lenses exhibit high optical clarity, excellent creep, and high-temperature resistance, making them perfect as TV/gamer/screen glasses.

Here are three essential benefits of blue light blocking glasses:

  • Relieve eye discomfort. The blue light filtering technology can enhance focus and reduce eye strain. (Another way to reduce eye strain is to take regular breaks from the screen.)

  • Help with better sleep. Excessive blue light exposure can negatively affect sleep patterns. With blue light blocking glasses, reducing the impact of blue light, we'll be able to use our devices before bed, and still get a good night's sleep. (The best option is to avoid the screen when it's time for bed.)

  • Help reduce the likelihood of AMD. AMD is a leading cause of blindness. Blue light blocking lenses can help avoid or delay this condition by preventing blue light from affecting your eyes.

Takeaway

Blue light is everywhere, and our eyes are not good at blocking it. With Livhò Blue Light Blocking Glasses, an incredible visual experience is guaranteed as we're enabled to protect our eyes while making the most out of our digital devices.
