It is recommended to reduce the amount of hours spent in front of screens, especially during the evening and nighttime. It is also helpful to adjust the settings on your devices to change their colour display during late hours, so that they emit less blue light in this period. However, reducing screen time isn’t the easiest thing to do, and that is why a lot of people opt for blue light glasses instead. It is an easy and inexpensive way to help your eyes and body experience less negative effects from blue light exposure, and is even recommended by Harvard Researchers. They state that blue light glasses have health effects such as improved sleep cycles and quality of sleep, better focus and reduced headaches.
