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 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 wave length that's between approximately 380nm and 500nm in visible light spectrum. "br""br""b"Natural blue light vs. artificial blue light:"br""br"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"br"Artificial sources of blue light include digital screens such as TVs, computers, smart phones, and fluorescent and LED lights. "br""br""b"CARE"br""br"To avoid damage, never contact with acid, and avoid using paper, towels, clothing, alcohol, household detergents or soaps to clean your glasses. While a few mild soaps don't harm lenses, today's extra strength soaps are strong enough to slowly disintegrate lens coatings.

Arctic sea ice has likely reached its minimum extent for the year, at 4.72 million square kilometers (1.82 million square miles) on September 16, 2021, according to scientists at the National Snow and Ice Data Center (NSIDC) at the University of Colorado Boulder. The 2021 minimum is the twelfth lowest in the nearly 43-year satellite record. The last 15 years are the lowest 15 sea ice extents in the satellite record.

Each September, the National Snow and Ice Data Center (NSIDC) at the University of Colorado Boulder informs the public of the annual Arctic sea ice minimum extent, an indicator of how climate change is affecting the Arctic, the fastest-warming region of the globe.

Scientists at Northern Arizona University, Arizona State University, the Arizona Geological Survey at the University of Arizona, and the National Snow and Ice Data Center at the University of Colorado Boulder have been awarded almost $2 million from the National Science Foundation (NSF) to develop a virtual reality teaching tool called Polar Explorer.

The National Snow and Ice Data Center (NSIDC) announced this week their participation in the 50x30 Coalition, a group of governments and cryosphere and emissions research institutions endorsing the need to reduce greenhouse gas emissions 50 percent by 2030. The Coalition’s founding members endorse the scientific consensus that failure to reach this milestone will result in temperature “overshoot,” in which emissions remain too high to hold Earth within 1.5 degrees Celsius of pre-industrial levels, leading to major and irreversible damages to the environment. Damage may be especially harmful for highly temperature-sensitive frozen components of the Earth system, with impacts ranging from sea level rise to infrastructure damage to food insecurity.

Arctic sea ice has likely reached its maximum extent for the year, at 14.77 million square kilometers (5.70 million square miles) on March 21, 2021, according to scientists at the National Snow and Ice Data Center (NSIDC) at the University of Colorado Boulder. The 2021 maximum is tied with 2007 for seventh lowest in the 43-year satellite record.
