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.

Why Cyxus uses Polycarbonate (PC) Lenses, while other similar products in the market are using the regular glass and plastic lenses (including other high-index lenses)?

The PC material used for eyeglass lens was developed in the 1970s by the aerospace industry for use in helmet visors worn by astronauts. Today, because of its lightweight and protective features, PC is used for a wide variety of products including space shuttle windshields, luggage, "bulletproof glass," helmet visors of astronauts and police, swimming goggles and diving masks, Eyeglass lenses made of polycarbonate were introduced in the early 1980s in response to a demand for lightweight, impact-resistant lenses.

Since then, PC lenses set the standard in eyewear safety, If you're looking for a durable material for kids, sports or safety eyewear, then Polycarbonate is an excellent choice. Polycarbonate can work in a variety of frame types, even drill mount frames which are frames that connect the lens directly to the temple arms on your glasses. Additionally, we provide SHMC technology, which includes oil resistance coating, waterproof coating, anti-scratch coating and dust free coating,  Anti-electromagnetic radiation on these lenses, because nobody likes dirty or scratched lenses, and they have UV420 protection, they will protect your eyes from UVA and UVB rays.
