It can also reduce contrast and decrease sharpness and clarity of vision. NVN Glasses are blocking 65% of high energy blue light and that helps minimizing strain/red/dry/watery/blurry/fatigue/irritated eyes and headaches when looking at digital screens for hours. ✅【INCREASE THE NATURAL SLEEPING PATTER】 Blue light in 450nm to 500nm wavelength range, which is known as low energy blue light, is generally considered beneficial. It provides for the right functioning of the circadian rhythm (sleep/wake cycle), memory and cognitive performance. But overexposure to low energy blue light will interrupt your sleep schedule. NVN Glasses are blocking 20% of low energy blue light and that helps production of melatonin that should increase the natural sleep patterns. ✅【100% UV400 PROTECTION】 Ultraviolet or UV light is electromagnetic radiation from the sun. We can’t see it, but it penetrates the earth’s atmosphere and reaches your skin and eyes in the form of UVA and UVB waves. These harmful rays can do nasty damage in any season. These light sensitivity glasses also come with UV400 protection. They protect your eyes against harmful UVA/UVB rays. ✅【PACKAGE】 Package includes a fashionable pair of blue light blocking glasses, a black pouch and a glass cleaning cloth.
