With Business by ANCR Copenhagen, you get beautiful, classic-looking glasses that filter more than 40% of the blue HEV light from your digital screens. The blue light can change your circadian rhythm and give you a bad night's sleep. No matter what you work on, you probably spend a large part of your working time every day in front of the screen - and may also continue at home in the evening when the family is put to bed. It puts both you at risk for sleep and other health problems due to the blue light from the screen.
