What's Blue Light?
Blue light is a color in the visible light spectrum（380nm and 500nm） that can be seen by human eyes. Blue light is a short wavelength, which means it produces higher amounts of energy. We have brought blue light inside by way of digital screens (found on TVs, Smartphones, computers, laptops, tablets, and gaming systems), electronic devices, LED and fluorescent lighting. Studies show that exposure to blue light can cause eyestrain, fatigue, headaches, and sleeplessness.
How Does Blue Light Affect Eyes
The fact that blue light penetrates all the way to the retina (the inner lining of the back of the eye) is important because laboratory studies have shown that too much exposure to blue light can disrupt your sleep circadian, cause eyestrain syndrome: blurry vision, dry and irritated eyes, headaches, neck and back pains, increase the risk of cardiovascular disease and cancers.
Sources of Blue Light
Sources of blue light: sun, LED + fluorescent lighting, electronic devices + digital screens (TVs, computers, laptops, smartphones/cell phones, and tablets/iPads)
Spending just two consecutive hours on a digital device can cause eyestrain and fatigue.
Who needs HEV-Absorb?
In this digital age, we all need protection from eye strain, afternoon headaches, and sleeplessness. Our HEV-Absorb is virtually clear lenses made with a special blue-light blocking polymer that prevents blue light and UV rays from passing through the lens. It is incorporated into the lens material which means the blue-blocking protection won't chip or wear away.
HEV-Absorb is for everyone!
HEV-Absorb is for digital screen users
The evolution in digital screen technology has advanced dramatically over the years, and many of today's electronic devices use LED backlight technology to help enhance screen brightness and clarity. These LEDs emit very strong blue light waves. Cell phones, computers, tablets and flat-screen televisions are just among a few of the devices that use this technology. Because of their widespread use and increasing popularity, we are gradually being exposed to more and more sources of blue light and for longer periods of time.
How many hours do you spend in front of a digital screen?
HEV-Absorb is for kids & teens
For children today, screen media is consumed from a very young age due to the growing use and presence of digital devices in their day-to-day lives. A 2017 study from Common Sense Media reveals that among children 8 and younger:
- 42% own tablet devices — a massive increase from only 7% four years ago and less than 1% in 2011.
- 98% live in a household with some mobile device and TV.
- 49% watch TV or play video games in the hour before bedtime.
- All spent an average of 2 hours and 19 minutes a day with screen media.
Children are especially vulnerable to the effects of blue light because their eyes have not yet developed natural defenses against UV and blue light. Their eyes need extra protection.
HEV-Absorb is for outdoor enthusiasts
Blue light is actually everywhere. When outside, light from the sun travels through the atmosphere. The shorter, high energy blue wavelengths collide with the air molecules causing blue light to scatter everywhere. This is what makes the sky look blue.
Cyxus HEV-Absorb not only blocks out the blue light but also provide 100% UVA & UVB protection, You can think of HEV-Absorb as sunscreen for the eyes.
