5 BENEFITS OF BLUE LIGHT BLOCKING GLASSES
1. Health is Wealth
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.
Blue light blocking eyeglasses promote healthy moods, prevent macular degeneration, and cognitive disorders- protecting against retinal DHA essential fats (DHA fats protects visual and neurological development).
2.New Advanced Technology
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 blue light clear cut, scratch resistant lens, blocks out approximately 90% of permanent blue light. It is scratch resistant, designed to be impact resistant, long-lasting, and durable.
3.Durable and versatile
Ideal for more than 80% of all prescriptions, Cyxus polycarbonate lenses can be mounted without scratching, cracking or breaking. They also allow various treatments, including photo chromic and polarized, making them the most functional and highest performing material in the industry.
4.A Healthy Night's Sleep
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. After a long day of using the computer, cell phone, or T.V., blue light blocking eyeglasses are used to sleep healthier at night. Stimulating a relaxed mind and relaxed eyes- restoring and preparing you for the next day.
