Glasses against blue light?
As awareness about the importance of light and it’s effect on our biorhythm is increasing, more and more products are coming to the market adressing this issue. Bluelight blocking glasses are all over the place, so what to look out for?
What do/should they do?
If you are wearing glasses, you might have been offered “bluelight filtering glasses”, which are mainly targeted at people working in an office, staring at a screen all day long. These glasses do not look any different from normal glasses, except maybe for a slight yellowish tint. They are intended to filter out the potentially harmful bluelight spectrum coming from an LED display, in order to avoid eye fatigue when working long hours on the computer. They do not, however, really block blue light altogether and are only marginally improving your evening light situation. A real “blue light blocker” should consist of clearly noticeable orange tinted glasses and filter out all blue light over a broader spectrum. Having said that, the effect on your biorhythm is still far more dependend on the amount of light, whether it’s warm or cold white. So if you cannot avoid bright light in the evening, consider wearing orange sunglasses.
