8-in-1 Coating Technology
Computer Glasses lens are made with advanced 8 in 1 (Hardened/SiO2/ZrO2/SiO2/ZrO2/ITO/SiO2/User) coating technology to effectively block UV400 and electromagnetic radiation, filter out high energy blue light and other harmful light, imitate natural condenser, reduce glare and improve contrast, and restore true colors
Information for blue light:
Blue light wave is one of the shortest, highest-energy wavelength that's between approximately 380nm and 500nm in visible light spectrum. Blue light is actually everywhere including the sun, digital screens (TVs, computers, laptops, smart phones and tablets), electronic devices, and fluorescent and LED lighting
Natural blue light vs. artificial blue light:
Natural blue light comes from the sun. Our body uses blue light from the sun to regulate our natural circadian rhythm (sleep and wake cycles), boost alertness, heighten reaction times, elevate moods, and increase the feeling of well being
Artificial sources of blue light include digital screens such as TVs, computers, smart phones, and fluorescent and LED lights.
To avoid damage, never contact with acid, and avoid using paper, towels, clothing, alcohol, household detergents or soaps to clean your reading glasses. While a few mild soaps don't harm lenses, today's extra strength soaps are powerful enough to slowly disintegrate lens coatings
Please double check the color or magnification strength you choose when check out. If you forget to choose, the defalut option will be added to the cart which is not what you want.
