cure for eye strain, digital headaches




What's Blue Light?

Blue light is a wavelength of between approximately 380nm and 500nm; making it one of the shortest, high energy visible (HEV) wavelengths. Because they are shorter, these "Blue" or HEV wavelengths flicker more easily than longer, weaker wavelengths. Studies suggest that, over time, exposure to the blue end of the light spectrum could cause serious long-term damage to your eyes.

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?

Your Eyes Do A Lot for You, Return The Favor with Cyxus Blue Blockers



Is HEV-Absorb a regular lens with a special coating?

No. HEV-Absorb blue blocker lenses are made with a special blue-light blocking polymer, that is directly incorporated into the lens materials. That means the blue- blocking technology won't chip or wear away. By absorbing blue light, this polymer prevents blue light from passing through the lens to your eye.

Does HEV-Absorb come with UV protection coating?

Yes. HEV-Absorb comes with a UV420 protection coating.

Is HEV-Absorb the same thing as computer glasses?

Yes and no. Cyxus's HEV-Absorb blue blockers are blue-light blocking lenses that are designed for all-day wear and protection from blue light. Whether you're a heavy computer user or not, HEV-Absorb lens blue blockers can be worn like regular glasses to protect your eyes from harmful blue light emitted from any digital device, as well as artificial fluorescent and LED light exposure. HEV-Absorb lenses are not like the yellow/orange-tinted specialty computer glasses designed specifically for computer and gaming use.

Should my child wear the HEV-Absorb lenses?

Yes! Children are especially vulnerable to the effects of blue light because their eyes have not yet developed natural defenses against UV and blue light. Now that smartphones, computers, and tablets are a regular part of kids' lives, they need blue protection more than ever.

How does blue light affect the eyes?

Prolonged exposure to high-energy visible (HEV) blue light can lead to eye strain and blurred vision. Studies have shown that it may also damage the retinal cells which can lead to an increased risk of developing age-related macular degeneration. Macular degeneration leads to vision loss over time. The HEV-Absorb blue blocker lenses block blue light and provide maximum UV coverage to protect your eyes.
